6.1 MASTER VOLUME
The Master Volume control is visible in the lower left corner of the bit Drive main window.
This Master Volume control can be used in the following ways:
◼︎ It can be controlled by an optional DRC AC
◼︎It can be controlled by an optional Maestro AR interface (see below for more information)
◼︎It can be controlled by an optional Audison B-CON in Absolute Volume mode (see the documentation with the B-CON for more information.
◼︎If none of these devices are connected to the amplifier, this setting defaults to 0dB.
Note: If an experienced user requires more gain, this setting can be boosted above 0dB, up to +6dB. To do this, the Volume slider must be highlighted, and the CTRL key must be pressed while moving the slider upwards to the desired level.
Note: If a value above 0dB is selected, make the corresponding change in the Volatile Data window (section 6.6.2).
The listening zones allow to split the output channels in groups, each one with its own level control. This is useful when the speaker distances are long and they be considered part of different listening environments. Each zone can hold one or more channels, to be associated as shown section 5.3.
In the main window there are two different panels for the zone control.

6.4 STATUS BAR
The status bar is in the right bottom side of the main window and provides some useful informations to the user.
bit Drive software notifications:
◼︎ Warning: notifies that there could be configuration problems leading to poor sound, or no sound. This happens for example if in the mixer one or more inputs are not used, or an output channel does not receive any contribution from the input signals.
◼︎ Info: useful infomations. This messages could show up for example when in the mixer an output channel receives a contribution higher than 100%, or when the delays set for the outputs do not match the speaker distances.
◼︎ OK: there are no potential errors in the setup.
The number close to each symbol shows the number of messages. Click on the bar to open the list with all messages.
Note: the messages in the status bar acts as reminders and can show possible errors or forgetfulnesses. However, It is not strictly mandatory to correct all the warnings to save the setup or finalize the device.
Note: the Notifications in the Status Bar act as reminders to the user, to prevent possible errors. However, Notifications do not prevent operation of the bit device, and it is not required to correct all warnings before saving the Configuration file, or Finalizing the device.

4. Release time: time delay from the trigger reception to the activation of the programmed action.
Press the icon in the command bar to open the programmable functions.
6.6.1 Turn On/Off delay: allows changing the turn on/off time settings of the device.
Note: This allows the installing technician to prevent any possible sonic artifacts due to the different turn-on timing of various devices in the audio system.
6.6.2 Default Volatile Data: set the initial settings for levels and other DSP functions when the device is turned on after that the supply cables were disconnected.
WARNING: If Volatile Data Settings are configured incorrectly, the audio system could stop working after a temporary loss of 12V power. This may cause certain safety systems in the vehicle to lose functionality. See Section 2.4 for more information on PROPERLY configuring Volatile Data Settings.
6.6.3 DRC AC: program the DRC functions. For more informations please read the following chapter.
Note: This function is not available offline.
6.6.4 Auto Chimes
The Auto Chimes function allows the correct reproduction of the car's service signals (reverse, parking sensors, door sounds, etc.) even when listening to music via Optical Source.
When activated, Auto Chimes constantly monitors the signal at all analog input channels (if they are enabled in bit Drive).
If you are playing music via Optical Source, and Auto Chimes detects audio signal at at least one of the enabled analog input channels, Auto Chimes automatically forces the switch to Master Source 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 (i.e. service signal ended), Auto Chimes automatically forces the switch to the previous Optical Source in use.
The Auto Chimes configuration panel is accessible from the Features window and includes the following parameters:
Enable/disable the function
Allows to set a memory to which the Auto Chimes switches the function is activated.
Time delay after which Auto Chimes switches back to Optical Source following the end of the service signal.
Minimum level threshold on Analog Input channels beyond which Auto Chimes activates to switch to Master Source
When Auto Chimes activates, the product's Master Volume momentarily switches to this value. When the service signal ends, the Master Volume will return to the previous music listening level.
COMPATIBILITY WITH B-CON
Auto Chimes can also be used when using a B-CON (regardless of whether it is connected via ADC port or not). In that case, Auto Chimes always takes priority.
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.
6.6.5 Auto Input switch
The Auto Input switch function manages the automatic switch from Master Source to Optical Source and vice versa when playing music through an external player connected to one of the Digital Inputs.
When activated, the Auto Input switch constantly monitors the signal at the chosen Digital Input (if enabled in bit Drive).
If you are playing music via Master Source and Auto Input switch detects audio signal at the Digital Input selected, Auto Input switch automatically forces the switch to Optical 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 Master Source.
The Auto Input switch configuration panel is accessible from the Features window and includes the following parameters:
Enable/disable the funcion
Allows to set a memory to which the Auto Input Switch switches when the function is activated.
Select the Optical source where the function must be enabled
Time delay after which the Auto Input switch activates and switches to the selected Optical Source following the detection of a signal on it (start of playback from the digital player).
Time delay after which Auto Input switch switches back to Master Source due to the end of signal detection on the Source selected (stop playback from the digital player).
Minimum level threshold on the Source selected beyond which the Auto Input switch activates to switch to Optical Source.
When Auto Input Switch activates, the product's optical volume momentarily switches to this value. When the function deactivates, the Master Volume will return to the previous listening level.
IMPORTANT: when using a B-CON connected with ADC port, the Device volume applies only at the first switch after turning on the B-CON. The following switches will keep the Optical volume set by the user either with DRC AC or mobile device (if Absolute Volume is ON).
COMPATIBILITY WITH B-CON
- B-CON connected via ADC port: Auto Input Switch can be used for Selected Memory and Device Volume. All other parameters are ignored and managed directly by the B-CON, so there is no need to program them.
- B-CON connected via MASTER EN and AUX SEL cables: Auto Input Switch can be used and always takes priority over any triggers set for the source switch via MASTER EN and AUX SEL cables.
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.
6.7 DRC AC
The remote controller DRC AC can be used to turn on/off the amplifier or to do a set of functions programmable on the bitDrive software.
The DRC AC remote controller can perform several functions, all of which are configurable in the bit Drive software.
6.7.1 TURN ON/OFF THE AMPLIFIER FROM DRC AC
Press once the knob to turn on the amplifier.
For the amplifier to turn on by DRC AC:
- the amplifier must be connected to power and properly configured;
- the PC Power On must not be active.
A long press on the knob of the DRC AC turns off the amplifier.
The DRC AC cannot turn of the amplifier if the amplifier has been turned on by 12V+ on the REM IN input, or by ART detecting DC offset on SPK IN input 1 and 2.
In order to turn off the amplifier by DRC AC:
- there must be no +DC signal on the REM IN pin of the CTRL port
- if the ART switch is Enabled, there cannot be speaker signal present on Input Channel 1 or 2 of the SPK IN input harness.
A long press on the knob of the DRC AC turns off the amplifier.
Note: The DRC AC cannot turn of the amplifier if the amplifier has been turned on by 12V+ on the REM IN input, or by ART detecting DC offset on SPK IN input 1.
In order to turn off the amplifier via the DRC AC:
- There must be no +DC signal on the REM IN lead of the CTRL harness
- If the ART switch is Enabled, there cannot be speaker signal present on Input Channel 1 of the SPK IN input harness.
6.7.2 DRC AC PROGRAMMABLE FUNCTIONS
When the DRC AC is connected to the AF bit, the bitDrive software detects its presence and makes the panel available to configure its functions. In the Features window (see sect. 6.6) there will be a third option to set the DRC AC as per picture below.
◼︎ Sleep mode: after 5 seconds without using the controller, all LEDs turn off except for one. The sleep mode is disabled as soon as the user comes back using the controller.
◼︎ Set LED brightness
◼︎ Programmable functions: the user can set up to 5 functions among
- Master Volume
- Source change
- Memory change
- Volume ZONE 1
- Volume ZONE 2
- Enable/Disable Final Tuning
- Sub group Volume
Important: at every change of the programmable functions, press the Finalize button to save the new settings into the DRC AC. Otherwise, the settings could be lost, and the system may not operate properly.
Once it has been configured, use the DRC AC as follows:
- Press the central part of the knob to move to the following function (among those that were enabled);
- Rotate the knob to change volumes;
- Press quickly two times the central part of the knob to change source, change memory and enable/disable the Final Tuning.
6.8 AUTOMATIC CHECK FOR UPDATES
In the Settings panel you can enable automatic checking for updates at startup (see section 2.2 INITIAL SETTINGS).
When this function is enabled, bit Drive checks for the latest versions of the software, amplifier firmware and DRC AC firmware on the Audison online portal when it starts.
IMPORTANT: An active Internet connection is required for update checking to work properly.
