9. RESCUE PROCEDURE

INTRODUCTION

The bit Wave software application is Elettromedia tool for calibration, configuration, and tuning bit DSP processors in the marine environment. It is compatible with select bit devices:

8 DSP (product for custom use)
V8 DSPx²
V8 DSPx² 24V

Future bit devices will add as they are introduced, thanks to the “future-proof” architecture of the bit Wave software.

Using bit Wave software successfully involves the following steps:

1. Software and firmware

Installing the latest software version available on hertz-audio web site
Updating the bit device firmware to the latest version available on hertz-audio web site

2. Configuring the bit device for first use.

3. Input and Output Setup using the Configuration Wizard

The Configuration Wizard includes automated testing for Polarity, EQ, and delay on the input signals. The user can elect to use the Wizard’s automated correction for EQ and Delay, or perform those manually in the next step.

4. Using the Input tools, including the Electrical RTA

to confirm the automated signal correction and add phase correction if needed. Also, if the automated process was skipped over in Step 3, the de-EQ, de-Time, and de-Phase processes can all be performed in Step 4.

5. Using the Output tools

including the Acoustic RTA, to achieve the desired acoustic result (“tuning”).

6. Configuring optional functions of the bit device.

1. SOFTWARE AND FIRMWARE INSTALLATION AND MAINTENANCE

The latest bit Wave software and V8 DSPx² firmware releases are always available for download from the HERTZ Support page.

1.1 FIRST-TIME PC SOFTWARE INSTALLATION

The bit Wave software can be installed in every PC equipped with Windows 10 or 11 operating system. For the installation it is important to have an active Internet connection, in order to ensure the download of the Microsoft .NET Framework files (these are needed for a proper functioning of the software) if they are not already installed in the PC.

Once the update is complete, the following warning window will be displayed, press OK to restart your device.

Press Close to close the update software.

Open the bit Wave software and verify that the firmware has been correctly installed.

2. PRELIMINARY CONFIGURATION OF THE DEVICE

2.1 INITIAL SCREEN

The bit Wave software has been designed to be compatible with bit marine amplifier with integrated DSP and future products in the Elettromedia catalogue. Thanks to a handshaking mechanism, the software detects the device connected to the PC and configures automatically its interface according the tools available for that device.

Bit Wave can also be used in Offline mode, if there is no available device to connect to the PC. Offline mode allows the software to exercise most of the bit Wave functions with virtual devices. The user can access almost all of the same tools which are available when an actual bit device is connected, including opening, modifying, and saving setup files for later use.

The Initial screen displays important information:

◼︎ Bit Wave software release number

The panel to select the device shows the different connection modes:

◼︎ USB: detects the device connected to the PC via USB port;
◼︎ SERIAL: detects the device connected to the PC via Serial port;
◼︎ NETWORK: detects the device connected to the PC via Wi-Fi (future function, not yet supported);
◼︎ OFFLINE: use mode with "virtual" bit device.
The Refresh button above the panel updates the list of connected devices. Use the Refresh button in case you connect a bit device after opening the bit Wave software.

After clicking the desired bit device, the software will start loading all the tools required for that device. The progress bar at the bottom of the window shows the percentage of progress of the loading process.

At the end of the loading procedure the main window will show up with all the tools, as shown below.

Note: For reasons of safety, when bit devices are first powered on, no sound will be audible from the speakers. This only applies if the device has not been previously configured. This is because the Mixer that manages the input-output routing is not yet configured.

2.2 INITIAL SETTINGS

At the top right of the screen the user can find the icons of the initial settings.

Opens the Audio settings panel for the Acoustic RTA tool.

◼︎ Input device: allows the user to select the audio input device to be used by the internal acoustic RTA. Only devices currently connected to the PC are displayed.

Note:

◼︎ Use a good-quality USB measurement microphone, or a good-quality XLR measurement microphone connected to a good-quality USB microphone preamp. Do not try to use the microphone internal to your PC. Microphones designed for musical recording rather than measurement will yield unpredictable results.

◼︎ When first opening the bit Wave software, you probably have not yet connected your measurement microphone - which would prevent you from making this selection at this time. However, this selection must be made before the Acoustic RTA function can be used.

Bands: to choose the number of audio spectrum frequency bands between octave (10 frequency bands), 3rd octave (30 frequency bands), 6th octave (60 frequency bands), 12th octave (120 frequency bands).

Average: to choose the time window length in which the average is calculated (short; normal; long). This setting modifies the responsiveness of the bar graph.

Microphone calibration file: load the microphone calibration file (in .txt format) if available.

Opens the general settings panel.

◼︎ Sampling frequency: shows the sampling frequency of the DSP used. This is not currently able to be changed.
◼︎ Languages: allows to set the software interface language.
◼︎ Enable shortcuts: enable/disable the keyboard shortcut options.
◼︎ Keyboard layout: set the keyboard layout to be applied for the shortcuts.
◼︎ Units of measure: allows to set the units of measurement to insert the speaker distances; options available are centimeters (cm) or inches (in).

Note: It is recommended to select the desired Unit of measurement before proceeding.

◼︎ Driver’s side: this helps keeping the graphical reference of driver position in the vessel image of the main window.
◼︎ Automatic snapshot: enables/disables the auto save function of the setup in the software memory, with refresh rate fixed at a 2 minutes.
◼︎ Check for updates on startup: enables/disables the automatic check of new software/firmware releases available for download on the web portal.
◼︎ Device reset: function that resets the product, restoring the factory settings. In this case all the data saved into the device memory will be erased.

It opens the shortcut map, including the choice for keyboard layout.

Opens the software quick guide.

2.3 SAVE AND LOAD A CONFIGURATION

bitWave allows the user to save the setup configuration to the PC, load a saved configuration file, and write the currently-loaded configuration file to the non-volatile memory of the bit device. These functions are available in the command bar at the top left, as shown below.

load the configuration from a file saved on the PC.

save a copy of the current setup as file on the PC.

writes the currently-loaded configuration file to the bit device’s non-volatile memory. This setup file will be retained even after powering off the device and powering it on again. When this operation is executed, the bit Wave software will warn the user that the current data written to the device memory will be overwritten.

◼︎ Click on YES to save the data.
◼︎ Click on NO to cancel the operation.

creates a printable report about the setup configuration.

2.4 VOLATILE DATA SETTINGS

When the amplifier’s supply power is disconnected, some settings of the device return to predefined values.

These conditions can be set in the software by clicking on

Features ->Default volatile data

The settings to be defined are:

◼︎Device volume (default is 0dB)
◼︎Source (default is Analog source)
◼︎Memory (default is Memory 1)
◼︎Subwoofer Zones volume (default is 0dB)
◼︎Zone Volume (default is 0dB)
◼︎Final Tuning Zone EQ enabled/disabled (default is enabled)

Click Turn On Enable to apply these parameters every time that the device turns on.

IMPORTANT: Be sure to configure these settings appropriately before finalizing the device to ensure proper operation every time disconnect/reconnect the power. In addition, the vehicle/vessel may not have sufficient volume, or sufficient level for the subwoofer, or may have poor sound level due to incorrect memory selection, or Final Tuning Zone disabled.

3. CONFIGURATION WIZARD - INPUT AND OUTPUT SETUP

The Wizard Configuration guides the user through the steps to define the main setup settings in few minutes and with automatic tools (such as de-EQ, etc.).

IMPORTANT: Please, remind that any modification to the I/O setup can be done at any time, even without running the Configuration Wizard.

Note:

◼︎Once the Configuration Wizard process begins, all Input EQ settings are restored to their defaults. Even if the Wizard process is not completed, these settings are reset to their initial values.
◼︎After the Configuration Wizard process is completed, all manual functions are available for use. These changes can be made without repeating the Wizard process.

The Wizard Configuration guides the user through the steps to define the main setup settings in few minutes, with the help of automatic tools. Optionally, automated de-EQ and de-Time can be performed during the wizard process.

PRELIMINARY CHECK BEFORE STARTING THE PROCEDURE

IMPORTANT:

◼︎before proceeding, the proper test tracks are required if you wish to perform de-EQ and de-Time. You can download them on Hertz Support page. Use only the test tracks specified for your product! Other test tracks may yield poor or wrong results.

◼︎during this procedure, we suggest to disconnect the SPEAKER OUT harness from the amplifier to avoid any risk of damage.

It is important to know in details the system to be tuned, since these informations will be asked during the wizard setup. In details:

◼︎What kind of Hertz source unit you want use
◼︎What kind of input source you want use (Pre In Analog/Digital Coaxial/A2B);
◼︎What kind of input signals (ex: Front Left or Rear Left or Subwoofer etc.);
◼︎How many zones
◼︎What kind of speakers (ex. Front 3-way or Sub stereo or Rear 2-way etc.);
◼︎Presence of passive crossover filters;
◼︎If there are companion amplifiers to increase the number of output channels
◼︎If the amplifier outputs will be used in Bridge mode to increase the power rate;
◼︎The distance of the speakers from the listening point, to set automatically the time delays.

START THE GUIDED PROCEDURE

Note:

1.To avoid any issues due to low battery voltage, connecting an 12V(24V) power supply (capable of 20A(10A) of current) to the battery is recommended.

2.VENEZIA V8 DSPx² feature PC POWER ON, which maintains the “on” state for the device as long as the PC is connected to the amplifier via USB.

◼︎ Connect the source outputs to the device inputs;
◼︎ Turn on the device and connect it to the PC. Launch the bit Drive application;
◼︎ Select the device connected on the splash screen;
◼︎ Click on the icon to start the Wizard Configuration;

Note: if the device already had a setup saved in its memory, it is suggested to do a reset procedure (check 2.2 INITIAL SETTINGS to know how to reset the device), restart the device and then run the Wizard Configuration.

1. Start

Press Start to start the wizard procedure.

2. Sources

In this section, the user can enable the inputs to use:

◼︎ Analog (Pre In)

4. Input sensitivity

Procedure for automatic calibration of the input sensitivity.

◼︎ Press Skip if the user wants to do this procedure manually.
◼︎ Press Start to run the automatic procedure.

◼︎ Play the track “1-SineSweep” from the source.
◼︎ Set all tone controls to zero (flat).
◼︎ Set Balance and Fader controls to the centre.
◼︎ Set the source volume to the maximum undistorted level.

◼︎ Manual setting: Set the sensitivity of each input by clicking on the drop-down menu to change the voltage scale. To choose the scale correctly, observe the color of the virtual LED:

Rosso -> voltage scale too low compared to the input signal (KO)
Colore assente -> signal absent or with too low level (KO)
Verde -> voltage scale greater than the input signal (OK)

Once the green color is obtained, it is recommended to reduce the voltage scale to the minimum value necessary to keep the LED green. In this way it is possible to take advantage of the maximum possible gain in the Input section.

◼︎ Automatic setting:
IMPORTANT: Do not perform this procedure with a low source volume level setting! Signal-to-noise will suffer resulting in high levels of noise. If a “loudness” function is active, the frequency response results at higher volumes will be poor

Once this volume level is selected, keep the volume at this level until the process is completed!

◼︎ All Virtual LEDs for all used input channels should illuminate green.
◼︎ At the end of the procedure, stop the track playing from the source

Note: If “no signal” is detected on a channel during this process, but the Virtual LEDs indicate that signal is present, ensure you are using the correct test track and try again. If the issue continues, skip to the next step and set the input sensitivity manually after the process is complete:

At the end of the procedure, the software shows at the bottom the loading bar of all the data set in the Wizard configuration.

4. ELECTRICAL RTA, INPUT EQ AND DELAYS

The bit Wave software includes a powerful tool for analyzing input signals, a multi-channel input analyzer called electrical RTA. The electrical RTA is displayed within the Input EQ window, and displays the effects of the Input EQ and Input Delay settings in real time.

It is recommended to use a full-range mono (correlated) pink noise signal (like Track 4 - Pink noise) with the electrical RTA.

The Input RTA does not measure phase, rather it allows various channels to be temporarily summed together and displays the result. To determine if two channels are in phase with each other, the user can sum them together: if the content of the two channels are the same amplitude, and are in phase with each other, the resulting measurement will increase +6dB. Any change less than +6dB in the sum indicates some degree of phase misalignment at that frequency. For more information on using this technique, see Hertz’s Technical Documents and educational information.

The user can select the INPUTS window and then press the Input equalizer button to open the tool.

The following window will appear:

a. Input selection

This menu allows selection of the input to be equalized.

b. Input phase polarity inversion

This allows to flip the Input phase by 180°, without need of changing the physical cable connections.

c. 12-band parametric Input Equalizer for each channel

This equalizer is Parametric in operation. Each band can be configured as a Peak EQ filter, a Low- or High-Frequency shelf filter, a notch filter, a 1st-order phase-inverting all-pass filter, or a 2nd order phase inverting all-pass filter.

Gain, Center Frequency, and Bandwidth values can be adjusted either with the virtual slider or by clicking in the text field and inserting the exact value by keyboard. When a band is selected, the corresponding point on the graph will be highlighted.

The filter types available are:

Peak EQ Filter.png Peak EQ filter: the user can select Gain, Center Frequency (any frequency between 20 - 20kHz), and Bandwidth (Q). +/- 12dB of gain is available. The Q value can be set between 0.5 and 16.

Shelf filter 1.png Shelf filter 2.png Shelf filter (Low or High): the user can select Gain, Center Frequency (limited to the lower or higher end of the frequency range, respectively), and Bandwidth (Q) from 0.5 to 1.41.

Tavola disegno 1 copia 5.png Notch filter: the user can select Center Frequency and Bandwidth. The Q value is variable from 1.44 to 16. Gain is not available.

Tavola disegno 1 copia 6.png 1st-order All-Pass filter: the user can select Center Frequency. A 1st- order all-pass filter gradually changes the phase 180° above a given frequency. Above that frequency, the phase will transition from normal to 180° inverted. Gain and Bandwidth are not available.

Tavola disegno 1 copia 7.png 2nd-order All-Pass filter: the user can select Center Frequency and Bandwidth. Gain is not available.
A 2nd-order all-pass filter gradually changes the phase 360°. At the Center Frequency of a 2nd-order all-pass filter, the phase value has been changed 180° (the change is halfway to completion). As the phase approached 360°, the signal is essentially back in phase with the signal below the 2nd-order all-pass filter. The Bandwidth (Q) controls the width of the filter, or, how gradually the phase changes from 0° to 360°.

Note: It can be useful to think of a 2nd-order All-Pass filter as changing the phase from 0° to 180° at the Center Frequency, and then back to 0°. While this is not a strictly accurate description from a technical perspective, it is a good functional description.

Special options premium OEM systems.

Some premium OEM system use asymmetrical crossovers and multiple all-pass filters in the transition bands, leading to out-of-phase conditions at specific frequencies.

A single EQ band in this case can correct an entire crossover slope, freeing up EQ resources and improving phase accuracy.

The available options are:

Tavola disegno 1 copia 2.png Hi-pass: High pass filter.

Note: this is applicable only to the first EQ band.

Shelf filter 1.png Shelf filter 2.png Lo-Pass: Low pass filter.

Note: this is applicable only to the last EQ band.

d. Equalizer settings

Equalizer bypass: temporarily disables the equalization applied to the selected input channel.

Equalizer reset: permanently resets the equalization applied to the selected channel..

Copy: allows you to copy the equalization applied to the selected input channel and replicate it to a selected list of channels.

Import from REW: imports EQ filters for the selected channel from the REW software.

REW is advanced software for acoustic measurements and automatic calculation of equalization filters. For more information, refer to the Help Center (REW - Room EQ Wizard Room Acoustics Software).

Help: opens the quick guide.

Allows each Input Channel to be delayed individually. The user can change by:

◼︎ Click in the text field, and Insert the value using the keyboard;
◼︎ Clicking the + and – buttons (fine set), to increment/decrement the delay by steps of ±0.01 ms:

To check for time delays in the source:

◼︎ play track 4 – Pink Noise and select the Input channel concerned
◼︎ add it with the channel of the same Front if present (for example if you want to check channel 1 – Front Left Tw, add it with channel 3 – Front Left Wf)..

a. If the electrical sum increases by +6dB at all frequencies, the two channels are aligned in time and phase and no further control is necessary.

b. if the resulting response has deep holes present at periodic intervals, a "comb filter", this indicates that a time delay is in use in the Source for one of these channels.

◼︎ To correct a comb filter trend, open the Delays tab in the lower-left corner of the RTA window. Add delay to the far channel (in LHD vehicles, this is usually the even channel). The comb filter should move to the right of the RTA graph, affecting higher and higher frequencies. Increase the delay until the response is flat.

◼︎ If the comb filter starts decreasing as you add delay to one channel, reset that channel's delay to "0 ms" and start adding the delay to the other channel you are adding instead

◼︎ The goal is to get a flat response to all frequencies.

Example of "comb filter" due to time delays inserted in the source.

Select the input and/or output channels to show in the monitor. The input channels are always black text, while the output channel labels follow the same colors applied in the main window.

Note: If multiple Input channels are selected, the analyzer screen will display the electrical sum of the selected channels. If an Input Channel and an Output channel are selected at the same time, they are displayed independently.

Shows the signals selected in the previous point. The input sum graph is shown with white color, while the sum of the outputs is light blue.

By pressing the right arrow the user can open the monitor settings. Once these settings are changed, the change is retained and will be unchanged the next time the bit Drive software is opened.

It is possible to adjust:

◼︎Bands: The resolution (that is, the number of Bands displayed) 1/3 = 30 bands, 1/6 = 60 bands, 1/12 = 120 bands.
◼︎ Average: Sampling average (very short, short, normal, long); (Normal or Long is recommended)
◼︎ Graph scale limits: Maximum and Minimum Graph scale limits These change the vertical resolution of the display. If too wide a range is displayed, changes in amplitude can be difficult to discern.
◼︎ Target Curve: Target curve for input correction.

EXAMPLE 1: one input channel

EXAMPLE 2: electrical sum of input channels

EXAMPLE 3: one output channel.

EXAMPLE 4: electrical sum of output channels.

EXAMPLE 5: electrical sum of input channels (blue) and electrical sum of output channels (red).

5.3 INPUT CHANNELS CONFIGURATION

On this panel it is possible to select, rename and assign the input channels of each source.

5.3.1 Analog Input Channels

The input channel can be renamed (max 16 fonts) and enabled/disabled.
It is suggested to disable the unused input channels.

this is only for reading, and it can be edited from the previous point.

The input sensitivity setting determines the input voltage required for the amplifier to reach rated power. If the input sensitivity setting is set too low for an input channel, that input will clip easily and the Input Virtual LED in the software will illuminate red.The signal level can vary from 0.6V to 6V RMS.

MANUAL CALIBRATION OF THE SENSITIVITY

◼︎ Play the track “1-Sine_sweep” from the source.
◼︎ Set all tone controls to zero (flat).
◼︎ Set Balance and Fader controls to the centre.
◼︎ Set the source volume to the maximum undistorted level.
◼︎ If the source has an internal EQ, make sure that the controls are set to zero (flat)..

Note: The Virtual LEDs in the bit Wave software do not indicate the maximum undistorted level of your source. The Virtual LEDs illuminate red when the input voltage exceeds the selected voltage threshold. To test for the maximum undistorted level of the source unit, use the electric RTA test tool on bit Wave, or an oscilloscope.

Note: For most head units, the rated output of the head unit is a reasonable starting point.

◼︎ Select the sensitivity value that does not cause any clipping of the input. Step by step, select higher sensitivities (decreasing values on the scale) until the clipping LED of the channel (4) starts red blinking. At this point go back with the sensitivity scale, step by step, until the LED stops blinking red.
◼︎ Repeat the operation for each of the used analog inputs.

The LED lights up with green color when signal is present at the input; it becomes red when the input is in saturation.

The LED illuminates green when signal is present for at least one of the inputs; it illuminates red when at least one input is saturating, or clipping.

5.3.2 Coaxial Input Channels

On this panel it is possible to enable/disable and rename the coaxial input channels. It is not possible to set the sensitivity since the digital signal is already set to 0 dB by default.

5.3.3 A2B Input Channels

On this panel it is possible to enable/disable and rename the A2B input channels. It is not possible to set the sensitivity since the digital signal is already set to 0 dB by default.

5.4 OUTPUT CHANNELS CONFIGURATION

The following picture shows the panel to configure the output channels.

A. Name: for each active channel the user can assign a name(ex. “FL TW” max 16 fonts).

B. Channel name: Channel name: defines the speaker type. The software will automatically set a proper crossover filter to avoid damages of the speaker.

C. Loudspeaker model: choice of the speaker model from the Hertz or Audison catalogue. The software will automatically assign a preloaded crossover filter optimized for that model performances.

D. Enable/Disable: enable or disable the channel

E. Bridge: This setting does not bridge the output channels of the amplifier - that is done by wiring the amplifier properly (see the manual for the amplifier being installed for more information on proper bridging wiring). This setting drives both channels with the identical output signal, and controls both channels of level with a single output control in the bitWave software.

Note: If powering a dual-voice-coil subwoofer with two stereo output channels, the Bridged setting can be used in software to link the two outputs together for tuning purposes.

F. Info: Displays if the active channel is an amplified output channel (SpeakerOut) ,preamplified output channel (PreOut) or A2B output channel (A2B).

G. Zone: assigns the channel to a speaker zone (group of speakers). The user will then be able to control the zone volume with a dedicated command.

5.6 MIXER

After defining the system Inputs and Outputs, the user must set the mixer to define the audio signal routing. The mixer allows to set each output signal as weighted sum of the input signals.

Click on the icon below to access the Mixer.

The Mixer has the following interface:

The tool is built as a matrix:

◼︎ Rows are the input signals of the selected source;
◼︎ Columns are the output signals.
◼︎ The yellow highlighted blocks are related to the Upmixer function.
◼︎ The blue highlighted blocks are related to the Bassmixer function

Note: If the user didn’t use the Configuration Wizard, the Mixer is set to 0% on all channels by default, and the system will not play any sound.

Each Output Channel can receive a contribution from any combination of Input Channels. This contribution is defined in a percentage value. The percentage value can be defined by using the arrow keys, using the + and - keys on the keyboard, or by clicking in the text field and entering the desired value.

The phase of each output channel can be reversed 180°, without affecting any other output channels.

Note:

1. If an input channel is disabled, the corresponding row will be empty; if an output channel is disabled, the corresponding column will be empty.
2. Each source has its own Mixer. If a source is enabled, but its Mixer has not been set yet, the Status bar will show a warning message notification in the lower right corner.
3. If an output channel is assigned to a different zone, it is important to select the zone that contains that channel to open the proper Mixer settings.
4. If the Mixer shows unused input signals or output signals that do not receive any contribution from the inputs, the Status bar will show a warning notification in the lower right corner.

MIXING ANALOG AND DIGITAL INPUTS.

In the Mixer of each Source available in the product it is possible to add also Input channels of other Sources. This function allows to create "customized" Mixers for each Source.

To add Input channels of other Sources you can press the button 5.6_3.jpg and select which Input channels you want to add, as per following example.

Each added Input channel can be removed anytime by pressing the button

Example 1: Mixer of the Analog Source with added channels from digital Coaxial Source.

Example 2: Mixer of the digital Coaxial Source with added channels from Analog Source.

IMPORTANT:

each output channel should receive a total contribution of no more than 100%. The only time that this 100% total may be safely exceeded is if the two summed channels do not overlap in their passband (i.e., non-attenuated) content. If the same frequencies are added together in the mixer in an amount exceeding 100%, digital clipping may occur. If questions arise, use the electrical RTA in the Input EQ window to verify the passband for each channel.

5.7 DELAYS AND DISTANCES

The following image shows the output delays panel:

◼︎select Distance if you want to insert the speaker distances from the listening point.

Note: please, remind that the distance value entering will erase and recalculate the time delay values for each output channel.

5.9 ACOUSTIC RTA

The feature shows the acoustic measure on the graph background, thus allowing the user to analyze how the setup behaves while using the software tools to tune. The use of this function requires an external USB microphone connected to the laptop. Bit Wave is compatible with all USB microphones up to 24bit resolution.

Note: Before using the Acoustic RTA, it is essential to select the acoustic measure settings (which requires the USB microphone be connected) (see sect. 2.2).

The Acoustic RTA is enabled by pressing the microphone button highlighted below in the command bar.

The analyzer displays the live measurement on the Graph background, thus allowing the user to observe how the system response changes while using the tuning tools. The amplitude of the analyzer measurement is displayed on the vertical scale, along the right edge of the graph.

Note: when the RTA function is active, certain functions, such as the audio settings icon and the INPUTS tab, are not accessible. Turn off the RTA measurement to gain access to those settings.

Note: Use a good-quality USB measurement microphone, or a good-quality XLR measurement microphone connected to a good-quality USB microphone preamp. Do NOT try to use the microphone internal to your PC. Microphones designed for musical recording rather than measurement will yield unpredictable results.

5.11 MEMORIES

◼︎The bit Wave software features 6 memories where the user can save different setups, selectable by software or by activating one of the Input Triggers

The control panel show the following options.

To select the desired memory

it is possible to rename and enable/disable each memory, with the exception of Memory 1 which has to be always active and enables for all sources.

Each Memory preset can be re-labeled.

Note: the user can create preferential memories for each kind of source. Consequently, when a source change is done the software will automatically select the first available memory that was enabled for that source type. Instead, if the user selects a different memory which is enabled only for a source different from the one currently playing, the software will automatically select the first available memory that is enabled for the currently playing source.

IMPORTANT: if Memory presets are left active but unconfigured, and the user accidentally selects a Memory preset without defined crossover filters, damage to the speakers may result!

The two best practices are:

◼︎Disable any unconfigured Memory presets to avoid accidental activation.
OR
◼︎Copy Memory preset #1 to any active presets without unique configuration settings.

Note: Press Turn On Enable if you want to apply these parameters every time that the device is turned on

6.6.3 Auto Chimes

The Auto Chimes function allows the correct reproduction of the service signals even when listening to music via Coaxial input.

When activated, Auto Chimes constantly monitors the audio signal at all analog input channels or A2B input enabled.

If you are playing music via Coaxial input, and Auto Chimes detects audio signal at least one of the enabled analog input channels or A2B input, Auto Chimes automatically forces the switch to Analog Source or A2B and keeps it active as long as the audio signal is present (i.e. until the service signal is terminated).

When the audio signal is no longer present (service signal ended), Auto Chimes automatically forces the switch to the previous Coaxial Source in use.

The Auto Chimes configuration panel is accessible from the Features window and includes the following parameters:

Enable
Enable/disable the function.

Source selected
Allows to set the source which the Auto Chimes detects audio signal.

Memory selected
Allows to set a memory to which the Auto Chimes switches the function is activated.

Threshold
Minimum level threshold on Analog or A2B Input channels beyond which Auto Chimes activates to switch to selected source.

Enable volume change
If you enable this setting, when Auto Chimes activates the Master Volume will be set to the chosen value. When the service signal ends and the product switches back to the previous Source, the Master Volume will return to the previous music listening level.

IMPORTANT:

COMPATIBILITY WITH AUTO INPUT SWITCH

Auto Chimes can also be used when the Auto Input Switch feature is enabled. In that case, Auto Chimes always takes priority.

6.6.4 Auto Input switch

The Auto Input switch function manages the automatic switch from Analog input to Coaxial A2B input.

When activated, the Auto Input switch constantly monitors the signal at the chosen Input (if enabled in bit Wave).

If you are playing music via Analog Source and Auto Input switch detects audio signal at the one of digital Input selected (Coaxial or A2B), Auto Input switch automatically forces the switch to the digital source and keeps it active as long as the audio signal is present.

When the audio signal is no longer present on the chosen digital Input, Auto Input Switch automatically forces the switch back to the Analog input.

The Auto Input switch configuration panel is accessible from the Features window and includes the following parameters:

Enable
Enable/disable the function

Memory selected
Allows to set a memory to which the Auto Input Switch switches when the function is activated.

Threshold
Minimum level threshold on the Source selected beyond which the Auto Input switch activates to switch to Source.

Enable Volume Change
If this setting is enabled, when Auto Input Switch activates the Master Volume will be set to the chosen value. When the function deactivates, the Master Volume will return to the previous Master Volume.

IMPORTANT:

COMPATIBILITY WITH AUTO CHIMES

Auto Input Switch can also be used when the Auto Input Chimes feature is enabled. In that case, Auto Chimes always takes priority.

6.6.5 Bass Boost

The Bass Boost features allow to set a programmable Gain for a specific range of frequency, in order to increase the Subwoofer(s) level

The subwoofer channel affect by Bass Boost can be programmable in the Mixer UI, by setting the contribution in the row at bottom.

The Bass Boost can be programmable as Fixed or Dynamic for each memory.

6.6.5.1 Bass Boost fixed

Boost is applied in a fixed mode with frequency, gain, and Q set for the desired memory.

Bass Boost fixed presents 3 parameters:

◼︎Gain: gain applied in the chosen frequency. Adjustable from 0 dB to +6 dB.
◼︎Frequency: center frequency at which the Boost is applied. Adjustable from 20 Hz to 300 Hz.
◼︎Q: Q-factor from 0.05 to 16.

6.6.5.2 Bass Boost dynamic

Dynamic Bass Boost provides a gain that varies according to the signal level determined by Subwoofer Input signal level, Subwoofer Input sensitivity and Mixer settings: a lower input signal level receives a greater bass boost than a higher input signal level, to compensate for the perceived different spectral balance.

The dynamic gain applied by the algorithm depends on the values of Lower Threshold (any input signal below this threshold will not affect the boost calculation) and Upper Threshold (any input signal above this threshold will not affect the boost calculation).

Bass Boost Dynamic presents 4 parameters to be set:

◼︎Gain[dB]: maximum gain applied in the chosen frequency. Adjustable from 0 dB to +6 dB.

◼︎Frequency [Hz]: frequency at which the Boost is applied. Adjustable from 20 Hz to 300 Hz.

◼︎Low thresh [dB]: Is the minimum level of the Input signal from which the algorithm start to apply the gain variation. Adjustable from -100 dB to -20 dB (A fixed gain is applied to input signal below the low threshold level).

◼︎High thresh [dB]: Is the maximum level of the Input signal below which the algorithm apply the gain variation. Adjustable from -5 dB to 10 dB.

6.6.6 Superbass

The Superbass allows to enhance the low frequency response with small subwoofer(s) connected to the amplified channel.

The subwoofer channel affect by Superbass can be programmable in the Mixer UI, by setting the contribution in the row at bottom.

The Superbass can enabled/disabled for each of the six memory presets, and does not require any further programming to be used.

6.6.7 Upmixer

6.6.7.1 What is the Upmixer

The Upmixer delivers multichannel sound from two channels of stereo input.

The Upmixer is very flexible and can be configured for a big variety of systems. The front left, right, and center channel outputs of the Upmixer deliver the stereo presentation. The rear surround channels increase the apparent size of listening area by enhancing ambiance.

The Upmixer includes three center-channel processing modes, with different levels of “gain” applied, to create the desired sound stage:

◼︎Wide: wide soundstage.
◼︎Default: standard soundstage.
◼︎Narrow: narrow soundstage.

The Upmixer block is totally configured within the Mixer in the bit Wave.

A -> Upmixer input (INL - INR): the Upmixer input block can receive a percentage contribution from each of the Input signals.

B -> Upmixer outputs (OUT L “front left” – OUT R “Front right” – OUT C “Front Center” – OUT LS “left surround” – OUT RS “Rigth Surround”: the Upmixer output block processes the signals received from the Upmixer inputs and generates 5 signals, each of these can be routed (as Inputs) to the Output channels with the desired percentage contribution.

Possible Upmixed System Configurations:

◼︎Front Stereo, Center-channel, and Sub (3.1)
◼︎Front Stereo, Center-channel, Rear Stereo, and Sub (3.2.1)
◼︎Front Stereo, Rear Surround, and Sub (4.1)
◼︎Stereo, Center, Rear Surround, and Sub (5.1)
◼︎Stereo Front, Stereo Rear, Rear Surround, and Sub (6.1)
◼︎Stereo Front, Stereo Rear, Center, Rear Surround, and Sub (7.1).

The configurations below all include a subwoofer, but the Upmixer does not provide a dedicated “.1” subwoofer channel - that is still defined in the Mixer. The Upmixer can also be used without a subwoofer if desired.

The Upmixer-processed channels can be routed to any desired output channels.

The bitWave Upmixer can be used with any source, or all of them together.

Note:

1. There is a Mixer configuration for each Input (Analog, Coaxial, A2B), which is active whenever the desired input is selected (in every case, this is regardless of the Memory Preset selected).

2. If the user desired one Memory Preset with upmixing and another Memory Preset with a traditional tune, lower the Center output channels to -40dB for the non-upmixed preset.

3. Rear ambiance channels can be effective regardless of whether or not a center speaker is used. 4.1 and 6.1 systems using rear surround channels for ambiance can provide great performance without a center speaker.

6.6.7.2 Configure the Upmixer

The Upmixer provides best results with 2 channels of flat, full-range, time- and phase-aligned signal.

The front and center outputs of the Upmixer are full range.

1. Ensure your Input channels are corrected to flat, full-range, and aligned in time and phase.

2. Using the Mixer, route these Input channels into the Upmixer.

3. Use the Upmixer output channels to supply signal to the desired output channels.

◼︎Front Left e Right
◼︎Center
◼︎Rear Surround

The subwoofer channels can be derived directly from any Input channel, or from the outputs of the Upmixer, as desired.

► 3.1 Front Left / Front Center / Front Right / Sub

Go to the Mixer
◼︎Route LEFT and RIGHT inputs into the Upmix IN L - IN R, as shown.
◼︎Use the Upmix OUT L and Upmix OUT R to supply signal for the Front Left, Front Right, and Subwoofer output channels.
◼︎Use the Upmix OUT C (center) to supply signal for the Center output channel.

► 3.2.1 Front Left / Front Center / Front Right / Left + Right Stereo Rear / Sub

Go to the Mixer:
◼︎Route the FRONT LEFT and FRONT RIGHT inputs into the Upmix IN L - IN R, as shown.
◼︎Use the Upmix OUT L (Front Left) and Upmix OUT R (Front Right) to supply signal for the Front Left, Front Right, and Subwoofer output channels.
◼︎Use the REAR LEFT and REAR RIGHT inputs to supply signal directly to the Rear Left and Rear Right output channels. Do not go through the Upmixer.

6.6.7.3 How to set the Upmixer for only one Input Source

It is possible to use the Upmixer with one Source and not the other.

To do so it is recommended to open the Mixer and operate only on the Upmixer input routing (columns UPMIX IN L and UPMIX IN R) since they remain independent for each Input Sourcee available.

IMPORTANT: please remind that the setting for Upmixer output signals (UPMIX OUT L, OUT C, OUT R, OUT LS, OUT RS) is shared between all Input Sources. Any change for these Upmixer outputs on one Mixer will be applied to all other Mixers too.

Example: Upmixer enabled for CENTER on Analog Input, but not on Coaxial input.

6.6.8 Power Dynamic Management

This function enables the dynamic modulation of the amplifier power, to reduce current consumption and avoid temperature increases due to installation in tight spaces without enough air flow.

6.6.9 EVOCA

6.6.9.1 What is EVOCA

EVOCA is a parallel equalization and dynamic processing architecture that pre-compensates the loudspeaker signal to precisely match predefined acoustic performance targets in terms of damping, extension, transient response and power handling.

6.6.9.2 How to configure EVOCA

1. Speaker models assignment

In order to use EVOCA you need to assign before a speaker model for each output channel:

◼︎Select the Channel and press the Edit symbol .
◼︎Select the Channel name from the dropdown list
◼︎Select the Loudspeaker model from the dropdown list.

2. EVOCA Menu

Output channels.

Assigned loudspeaker model.

For each output channel, select the wiring connection (single, series or parallel). This choice indicates whether the speaker is used single, series or parallel (or both) with another speaker(s) of the same model (e.g. dual woofers on the same channels). The number of speakers affects EVOCA internal parameters.

This choice, specifies how the speaker is physically installed. The Box type options are specific for each speaker and they correspond to the ones listed in the speaker model manual.

Note: some speakers only have one option available (e.g. Hertz HTX only the Fixed option is available).

For each memory you can enable or disable EVOCA. When EVOCA is enabled, select the EVOCA preset from the dropdown list. Each EVOCA presets correspond to a specific set of EVOCA internal parameters.

◼︎BALANCED: highlight the system’s well-damped response, minimal coloration, and suitability for high fidelity listening practice.

7. BITWAVE MULTIPLE INSTANCES - HOW TO TUNE TWO PRODUCTS WITH ONE PC

Bit Wave features the multiple instance mode of the software. This feature allows you to simultaneously open two instances of bit Wave on a single PC to:

◼︎simultaneously configure two amplifiers connected via USB to the same PC;
◼︎configure an amplifier connected via USB to the PC and open a setup file in Offline mode for reference.

7.1 CONFIGURATION OF TWO AMPLIFIERS CONNECTED WITH USB TO THE SAME PC

IMPORTANT:

This mode inhibits some functions of the software in the second bit Wave instance (identified by the abbreviation multi), and could cause incorrect operation even in the first instance.

◼︎Input Delay/Polarity check in the Configuration Wizard
◼︎Input de-eq in the Configuration Wizard
◼︎Electrical RTA in the Input Equalizer window
◼︎Audio monitor

Therefore, if you want to make full use of these functions for both products, it is advisable to do so with the amplifiers connected to bit Wave one at a time (so not at the same time) and without using this mode.

Follow these steps:

1. open bit Wave and connect to the first amplifier.

2. Open the path C:\Program Files (x86)\bit Wave, and run the bit Wave (multi) Shortcut file.

3. A second Splash screen of the software will show up.

4. Connect to the second amplifier in the list. A second window of bit Drive will open, named as bit Wave (multi) to be differentiated by the first.

5. At this point it is possible to configure and finalize the two amplifiers independently through the two instances of bit Wave.

7.2 CONFIGURATION OF AN AMPLIFIER CONNECTED WITH USB TO THE PC AND OPENING OF A SETUP FILE IN OFFLINE MODE

Follow these steps:

1. open bit Wave and connect to the amplifier.

2. Open the path C:\Program Files (x86)\bit Wave, and run the bit Wave (multi) Shortcut file.

3. A second Splash screen of the software will show up.

4. Select the Offline mode and choose the virtual model to open the reference setup file.

5. A second instance of bit Wave will show up, named as bit Drive (multi) to differentiate it from the first.

6. Open the reference setup file in this second instance.

7. At this point it is possible to configure and finalize the amplifier connected and to view at the same time the reference setup file in Offline mode.

8. REW - IMPORT EQ FILTERS IN BITWAVE

IMPORTANT:

REW compatibility is available with REW version V5.31.2 or higher (download available on REW website).

The REW Import Function allows to Import EQ filter settings from REW, a free software very popular for acoustic measurement and automatic EQ calculations. For more informations read the REW Help Center.

8.2 REW IMPORT ON FINAL TUNING EQ

Please read section 5.11 FINAL TUNING EQUALIZER

9. RESCUE PROCEDURE

This procedure must be used in case of FW upgrade that was not successfully completed, which cause missing turn on of the amplifier or other malfunctioning.

◼︎Disconnect the power supply from the amplifier and wait at least for 5 minutes.

◼︎Connect the amplifier to PC using the provided USB cable, a red LED will light up inside the amplifier’s USB-C port to indicate that it entered in rescue mode.

◼︎Download the firmware from the HERTZ Support page. A folder named 8DSP_FWupd_x.x.x.x will be available in the Downloads folder.
◼︎Open the folder 8DSP_FWupd_x.x.x.x, and click the file 8DSP_FWupd_x.x.x.x.exe.

The following window will appear:

◼︎make sure to read all the warnings, then click Update to start the procedure.

Note: During this process the amplifier led bar light is OFF.

◼︎at the end of the update the following warning window will be displayed:

◼︎DISCONNECT the USB cable in order to exit from rescue mode, click OK then Close to exit from the upgrade software.
◼︎connect the power supply and turn ON the amplifier.
