TROUBLESHOOTING SECTION
- If you receive error messages when installing the software or the drivers, check if the user account you are using on
your PC has admin privileges.
- If the PC shows an error message regarding the connection with the Bit One (for example “Bit One device not
found”), check the following points:
• If the DRC display shows the message “audison: vol bal fad sub”:
There should be a fault in the PC, for instance due to a wrong installation of the software or the drivers, or due to
undetectable problems, on an operating system or hardware level.
• If the DRC display shows the message “PC control - DRC is disabled”:
In this case the PC is correctly initializing the AC Link bus but the fault is in the interfacing with the PC. Exit the
program on the PC, turn the Bit One off then on again, then try reconnecting.
If after turning on the Bit One again one of the above messages appears, you may need to perform the AC Link drivers
installation again.
You may be required to uninstall and reinstall the drivers also if other applications overwriting, even partly, the AC Link
drivers have been installed.

HOW TO CONNECT THE BIT ONE TO THE PC
To adjust the Bit One functions the software is required. The processor needs to be connected to the PC and turned
on. After installing the software, start it by clicking on the icon shown on your desktop.
The first screenshot showing up is the start up page where you need to choose among:
- OFFLINE mode, Bit One not connected;
- TARGET mode, Bit One connected;
- RESCUE mode, Bit One connected for Update/Rescue (see page 37).
To select the start mode select the corresponding entry on the drop down menu, then press ENTER or double click
on the Bit One image.
OFFLINE MODE
In this case even if the Bit One processor is connected to the PC, it does not interact with the software.
The OFFLINE mode can be used to work on the software without connecting the Bit One to the PC, to get familiar with the
processor multiple functions. For more information on the specific functions, see the following pages on this Manual.
The software is pre-set to start with a 3-way + stereo Sub active multi-amplified system.
To set a new “virtual” system, and so to change the inputs and select the outputs, you need to select the function I/O
Configuration Wizard in the “Config” window of the software main menu. (See point n. 4 of the TARGET mode below).
Here is how the Bit One software appears when it is started up in OFFLINE mode.
ADVANCED MANUAL / Bit One

1. The software performs a scan of the PC port looking
for the Bit One; this operation won’t repeat again, unless
the installation settings of the PC hardware change; this
screenshot will show also if you select the TARGET mode
with the Bit One shut down.
2. Once the processor has been detected by the system,
the software will store the connection previously selected
and won’t perform that search on the next turn-on’s. (even
if on each turn-on a different USB port is selected).
POSSIBLE ERROR MESSAGE
3. Bit One NOT found
For some reason the processor is not recognised as
connected to the PC.
Press CANCEL to start up the OFFLINE mode.
TARGET MODE
In this case the Bit One processor has to be connected to the PC and turned on, otherwise the software won’t even
show the TARGET entry as selectable on the start up window.
At this point you need to have in mind the system you want to realize beforehand, since from this moment if you want
to change any of the settings you will have to go through the guided procedure all over again.
More specifically the guided procedure will ask for:
- Which main inputs you want to use (high or low level). Once you select your choice, auxiliary low level or digital
sources can anyway be added. The guided procedure changes according to the selected choice.
- Which auxiliary inputs will be used (ex. : AUX1 or DIGITAL IN or PHONE etc. ).
- Which kind of signals will be allocated to the different inputs (ex. : Front Left or Center or Subwoofer etc. ).
- Which speakers you are using for your system (ex. : 3-way Front or stereo Sub or 2-way Rear etc. ).
- If the system features passive crossovers managing speaker groups (ex. : 3-way system with active mid-low).
- If the system features any speaker connected through the AC Link
The procedure starts automatically.

5. Inputs selection
- Select the main inputs (MASTER) type (Low Level or High
Level) used. To change this setting afterwards, you will
have to go through this guided procedure all over again;
- Among the available auxiliary inputs (AUX1 - AUX2 - S/P
DIF - OPTICAL – PHONE) pick those that wil be used.
You can change this setting afterwards by selecting
“Config / External Source” on the software main menu.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the set-up procedure.
Press CANCEL to exit the program.
MASTER LOW-LEVEL INPUTS SELECTION
6. How to set up low-level inputs
An identifying name corresponding to the signal coming
from the source can be assigned to any of the processor
input channels (Ch1÷Ch6). The available names are:
Front Left, Front Right, Rear Left, Rear Right, Center,
Subwoofer. The Bit One will use these names to assign
the corresponding signal to the respective output.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the set-up procedure.
Press CANCEL to exit the program.
7. How to calibrate the MASTER inputs level
Follow the instructions listed below:
- Insert into the CD player of your head unit the
“Installation CD” provided;
- Play track 1 (press Play);
- Set all tone controls to zero (0);
- Set balance and fader to center (0);
- Adjust the head unit volume to the maximum undistorted
output level.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the set-up procedure.
Press CANCEL to exit the program.
Remark: calibration is absolutely required to adapt the
Bit One inputs sensitivity to the signal coming from the
source.
8. Automatic calibration
Through a real-time progress bar and specific messages
the software shows how the procedure is being executed.
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 go ahead with the set-up procedure.
Press CANCEL to exit the program.

POSSIBLE ERROR MESSAGE
9. “Input level too low“
Should the procedure get interrupted during the
calibration with the above message showing up, check
if the signal or its level is present on the indicated
corresponding channel.
Press CANCEL to log out the program.
Press BACK to go back to the inputs set-up.
10. How to select the speakers available in the
system
Speakers can be selected just by clicking on it.
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 has been started up, this choice will
affect the dedicated crossover type. Ex.: if on the rear
system only the woofers were activated, the software
will show exclusively 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 after
that (see point n. 11) you need to enter that a passive
crossover connecting one to the other is present in the
system, so the software will show a high-pass filter as
available.
Press BACK to go back to the previous step.
Press NEXT to go ahead with the set-up procedure.
Press CANCEL to exit the program.
From this point on follows a simulation of a system made
up of:
- 3-way Front/ - 2-way Rear / - 2-way centerl / - mono Sub.
The Bit One features 8 output channels. To multi-amplify
each single speaker of the system 13 output channels
would be required. In that case the software would
automatically signal the limit.
11. How to select passive crossovers for speaker
groups
While carrying out the configuration of your system,
you can also set the presence of passive crossovers
managing speaker functional groups in complex systems
Ex.: 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 set-up, 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 go ahead with the set-up procedure.
Press CANCEL to exit the program.
Here is how the system speakers selection is
shown by the Bit One software
