The selection of I/O configuration using the "PASS THROUGH" allows the interface in direct configuration between inputs and outputs. Moreover, during the guided procedure it allows to divide the emission front in order to increase the number of existing ways per front. The peculiarity of this configuration is that it does not provide any equalization, correction of time delays, phase variations and channel sums, allowing subsequently only to intervene on time and phase alignment equalization for the Master input. When using the other auxiliary inputs (AUX, Optical 1/2) it is also possible to separate the Master setup by creating one that performs better than the limits set by the OEM system.
Remark: if the Master configuration features Rear Surround channels, during the selection of the auxiliary inputs these will not be available. The procedure must be performed by selecting which memory to assign the Master Pass-Through input from the start.
1. Inputs selection
- The type of input available for Pass-Through mode is High level. This type of approach has the function of being able to maintain all the audio features of the OEM system.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
2. Analog inputs configuration
The inputs can be selected by clicking on the system’s loudspeakers assigning the corresponding channel number. Based on the analog input type there will be 12 input channels to be manually customized. In Pass-Through mode it will be possible to interface with 5.1/7.1 factory systems without losing any functions of the dolby digital systems.
Remark: this is possible at this stage of the setup graphically define the guide of the Left (default) or right car.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
3. MASTER analog inputs levels calibration
Calibration is absolutely required to adapt the bit One HD Virtuoso inputs sensitivity to the signal coming from the source.
- Press BACK to go back to the previous step.
- Press NEXT continue with the inputs calibration.
- Press SKIP to bypass the inputs calibration procedure.
Follow the instructions listed below:
- Insert the supplied CD.:
- Select the type of Test tracks contained in the USB device "SETUP31" (supplied with the product) according to your source (Head Unit), as shown below.
- “Wav Test Tracks Setup” folder if your source can play Wav format files.
- “MP3 Test Tracks Setup” folder if your source can not play Wav format files but only MP3.
- “5_1 Test Tracks” Folder if your source can play 5.1 multimedia files.
Remark: the different types of tracks are available and downloadable from the Audison website (www.audison.eu), in the download section of the product bit One HD Virtuoso.
- Play track 1 (press Play);
- Set all tone controls to zero (0);
- Set balance and fader to center (0);

Remark: the calibration is essential to adapt the bit One HD Virtuoso sensitivity to the signal coming from the source.
Important Remark: the head unit level must be elevated to the maximum undistorted level.
If the head-unit level can not be tested in advance, bring the volume adjustment to approximately 80% of its maximum excursion. If the head-unit output level is set at a lower level the bit One HD Virtuoso will produce a ground noise (hissing sound). Should such noise come from the bit One HD Virtuoso during reproduction, the calibration procedure will need to be repeated at higher volume.
4. Input level automatic calibration

Once the procedure is completed, the window will show the message “Press Next to Continue”.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
Once the procedure is completed the window will show the sensitivity levels setup according to the source interfaced with the bit One HD Virtuoso.
This window is active and a further manual sensitivity adjustment can be performed.
Select:
- Ref: 0dB Reference setup referring to the use of music tracks recorded at 0dB.
- +3dB - +6dB: referring to the Use of music tracks recorded at a level lower than 0dB
(-3dB ÷ -6dB).
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
ERROR MESSAGE MAY APPEAR
“Input Level too low”

- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
6. Channel Bandwidth Analysis
The analysis procedure of the emission front performs a study of the electrical frequency response coming from the source’s various channels. This operation is necessary to be able to reconstruct the exits at the subsequent points following the trends of the inputs.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Analysis of the emission fronts.
The analysis procedure of the emission front performs a study of the electrical frequency response coming from the source’s various channels. This operation is necessary to be able to reconstruct the exits at the subsequent points following the trends of the inputs:
a. OEM source equalization response;
b. Electric response of the channel filters that make up the front;
c. Display of the time delays of each individual channel of the emission fronts.
And follow the instructions listed below:
- set 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 interfaced source fronts will be displayed. The frequency trend of the signal will be displayed (Master EQ), and the trend of any input filters (XOVER) present. Clicking on each individual chart on the front, it will be possible to enlarge the trend of each individual front. This window can also display the presence of time delays of the source if any.
Remark: this operation has no corrective effect, it is only an analysis.
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
8. Selection of the speakers available in the system
Speakers can be selected just by clicking on them. The software assumes that if you select left tweeters, midrange or woofers, the right ones will also be activated automatically. This choice will affect, once the software is started, the type of dedicated virtual crossover.
Remark: if you selected the FIR mode the bit One HD Virtuoso will have a maximum of 9 out channels to enable.
Pass-through 1:1
In this configuration the number of output channels is equal to the number of input channels. So if you have 8 channels in input it will be possible to have a system with 8 channels in output. The Software, however, will make other speakers available to increase the ways (see following point).
Extended PASS THROUGH
In this configuration compared to the previous one it was decided to extend the number of output channels with respect to the same input configuration. In fact we would have 3 channels Front Out stereo compared to 2 channels Front Input stereo, and 2 channels Rear out Stereo compared to a Real Full stereo system.
At the end of the setup:
- Press BACK to go back to the previous step.
- Press NEXT to continue with the configuration.
- Press CANCEL to exit.
9. 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 13 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 with the configuration.
- Press CANCEL to exit.
10. Processor outputs (Ch1÷Ch13 IIR MODE) allocation
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.
11. Selection of the amplifiers connected through the AD 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.
12. Finish
System configuration successfully completed. Stop playing the Test track, remove the supplied Setup CD from the head unit CD player and then press OK.
