The choice of I/O configuration using the "Automatic Routing" provides the ability to interface with your source outputs automatically, allowing you to specialize the inputs and the outputs after analysing them. The procedure can be performed completely in the following way:
a. Master Delay / Polarity Check.
It allows to identify and compensate for possible time delays and electric phase inversion of the OEM source interfaced with the bit One HD Virtuoso;
b. Master DE-EQ / Phase Alignment.
It allows the user to carry out an analysis of the emission fronts, in this case the Equalization curve is identified, any All Pass present, compensating them if necessary. Furthermore, an analysis is made of the progress of the channels that make up the front in order to manually compensate for any crossover points.
c. Auto Input Switch.
activation of the automatic control of the auxiliary source (Aux - Optical 1/2) by controlling the volume of your vehicle's audio source (see sec. 5.4.3 - 5.6.1)
The software allows the user to select all three points or just the ones needed to get the best performance from the audio setup.
1. Inputs selection
- Select the main inputs (MASTER) type (High Level, Low Level, or Optical 1) used. If you select the Master Optical 1 input go to point 8, otherwise continue to point 2.To change this setting at a later stage, the I/O Configuration Wizard guided procedure will have to be performed again.
- Select among the available auxiliary inputs, AUX - OPTICAL 1 - OPTICAL 2, the ones which will be used. The setting can be changed at a later stage by selecting “Config / External Source” on the software main menu.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
2. Analog inputs configuration

A) Master Delay compensation:
- is not necessary: the source has no time delays set;
- is necessary: the source has time delays set.
By selecting Enable the output time delays will be compensated.
B) Speaker IN Polarity Check Result:
- The presence of green checks next to the loudspeakers indicates that the electrical connection of the inputs with respect to the source outputs has been performed correctly.
- The presence of red checks next to the loudspeakers indicates that the connection of an input or multiple inputs was made by inverting the cables.
You can proceed as follows:
- Select "Automatic Polarity Correction", the software will invert the phase to all the speakers displayed in red.
- Select "Manual electric Polarity Correction", the software will only inverse the channels selected in red and inverted manually.

- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
6. Source De-equalization / Phase Analysis
Operation not mandatory, but necessary for equalized OEM sources.The de-equalization process performs an analysis of the electrical frequency response comingfrom the different channels of the OEM source, automatically applying an equalization contrary to the original one, thus generating a linear signal, much more suitable to drive high quality audio systems.Regardless of the input channels used, the de-equalization will be performed for each functional group.
E.g.: even though Front Left Full and Front Right Full inputs are used, the software will perform the de-equalization also on Rear, Center and Subwoofer inputs as the processor will have to use the signals identified as Front to possibly also manage the Rear, Center and Subwoofer outputs.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press SKIP to bypass the de-equalization procedure.
￭ De-equalization procedure fase
In addition to analysing the equalization curve of the OEM source, the procedure is able to identify and compensate for any All-Pass filters present on the emission fronts.
If you decide to carry out this complete procedure put the check mark on "Phase Analysis" and follow the instructions below:
- Iset all tone controls to zero (0);
- set balance and fader to center (0);
- do not change the volume level previously set through the inputs level automatic calibration;
- play track 2 (press Play);
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.

7. INPUT Analysis Dashboard.
At the end of the procedure the results of the analysis of the fronts of the interfaced source will be shown. By selecting Module the frequency trend of the signal will be displayed (Master EQ), the curve calculated to compensate for the present equalization (Master De-Eq), the trend of the sum (SUM), in addition the software will calculate the trend of any input filters (XOVER) available. Clicking on each individual chart on the front, it will be possible to enlarge the trend of each individual front. It is also possible to display in this window the presence of time delays on the source if analysed, if any.
By selecting Suggested All Pass, instead, the phase compensation of the fronts suggested by the software will be displayed. It is applied via All-Pass first and second order filters according to the OEM source algorithm. In addition the software will display the electric response provided by the fronts selection, to inform the user about the suggested compensation. It will be possible after the end of the "I / O Configuration Wizard" to optimize the positioning of these filters or enable them (see sect. 8.8.1)
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
8. Auto Input Switch
The automatic volume control for the auxiliary source (Aux - Optical 1/2) can be activated through the Head Unit volume control, if it is provided with an AUX input (see sec. 5.4.3, 5.6.1; 8.3.5).
If the car HEAD UNIT does not have an AUX analog input, connect a USB memory (or SD Card) to the USB reader of your audio source as shown to the side. The USB/SD device must contain the mp3 format file available in the RVA TONE folder located inside the Setup CD (these files can also be downloaded from the Audison website).
Please note that the storage device must only contain this file and no other files.If you use the USB memory to activate the switching via the RVA function, simply select the USB (SD) or Master input.

9. Selection of the speakers available in the system
Speakers can be selected just by clicking on them. If the left tweeter, left midrange or left woofer are selected, the software provides the ability to automatically activate also the right tweeter, right midrange or right woofer. Once the software is started, this choice will affect the dedicated crossover type.
E.g.: if on the rear system only the woofers are activated, the software will only show a low-pass or band-pass filter as available. If you want to use a coaxial system as rear channel, both tweeter and woofer need to be selected and then you need to specify that a passive crossover is connecting them, so the software will show a high-pass filter as available.
Remark: if you decided to use the FIR mode the bit One HD Virtuoso will avail of a maximum of 9 output channels to be enabled.
- Press BACK to go back to the previous step.
- Press NEXT to go ahead with the configuration.
- Press CANCEL to exit.
From this point onwards a simulation of a system with the following components will be used:
- 3-way Front active
- 2-way Rear active8
- 2-way center passive
- Stereo Sub;
All 13 output channels of the bit One HD Virtuoso in IIR mode will be used.
Remark: Audio systems with at least 4-way front or 3 Rear are not fully compatible with AV bit In and bit Tune.
10. Selection of passive crossovers for speaker groups
The presence of passive crossovers managing speaker functional groups in complex systems can be provided by the user.
E.g.: the 3-way Front can be managed as
- multi-amplified (6 output channels would be required);
- passive mid-high speakers + separately amplified woofer (4 output channels would be required);
- 3-way passive (2 output channels would be required).
While performing the setup, the software will automatically notify the return within the 8 output channel limit, the warning message will then disappear and the NEXT button will appear.
- Press BACK to go back to the previous step.
- Press NEXT to continue the configuration.
- Press CANCEL to exit.
11. Processor outputs (Ch1÷Ch13 IIR MODE) assignment.
The bit One HD Virtuoso features 13 output channels. On this specific step of the procedure, any signal can be assigned to each output channel.
E.g.: the outputs 1 and 2 can be assigned to the rear channels simply to avoid having to lengthen the cables going to the specific amplifier.
For a matter of convenience, if the output 1 is assigned to the left woofers, the software will automatically assign the output 2 to the right woofers. If during the procedure the output 1 is assigned also to the left mid-high speakers, the software will show a warning message. Change the allocation of one of the two numbers marked in red and the software will automatically select the first available channel.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
12. Selection of the amplifiers connected through theAD Link / AC Link connection system
If the system features amplifiers provided with the AD Link digital input and you want to connect them to the system, you need to select them on this setup procedure window.
The CH1-CH8 output channels will be available on the AD LINK 1 socket, while the CH9-CH13 channels will be available on the AD LINK 2 socket.
Remark: remember to assign the corresponding Amp ID to the specific amplifier. The bit One HD Virtuoso will automatically recognize the identified amplifier.
