used. To change this setting later on, you will have to perform
again the I/O Configuration Wizard guided procedure.
- Select among the available auxiliary inputs (AUX1 - AUX2 - S/P
DIF - OPTICAL - PHONE) those that will be used. You can
change this setting later on by selecting “Config / External

1. How to set up the 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.
Remark: calibration is absolutely required to adapt the Bit One inputs sensitivity to the signal coming from
the source.
2. How to calibrate the MASTER inputs levels
Follow the instructions as listed below:
- Insert the supplied disk:
• insert the “Setup CD” if the head unit you are using is an
AUDIO CD Player
• insert the “TEST Signal DVD” if the head unit you are using is a
Dolby Digital (AC3) “Audio Car Theatre 5.1” featuring analog
outputs, or if it is an analog audio system featuring a central
channel.
- Play track 1 (press Play);
- Set all tone controls to zero (0);
- Set balance and fader to centre (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.
8.4 SELECTING THE MASTER LOW-LEVEL INPUTS
WARNING:
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
will produce a ground noise (hissing sound). Should such noise come from the Bit One during
reproduction, you will have to repeat the calibration procedure this time at higher volume.
