Setting the source.
-
Turn on the system and play track 1 of the CD supplied with the
bit Ten
.
-
Set all tone controls to zero (flat).
-
Set balance and fader to center.
-
Adjust the head unit volume to the maximum undistorted output level.
-
If the source provides an adjustable equalizer, make sure that all controls
are set to zero (flat).

WARNING
the head unit level must be elevated to the
maximum undistorted level
. If the head unit distortion level
can not be tested in advance, bring the volume to approximately 80% of its maximum. If the head unit
output level is set
too low
, the device will produce
ground noise
(hissing sound) when playing music
tracks. This is due to the low signal / noise ratio provided by the
bit Ten
input head unit.
If you have this problem, after you
calibrate the amplifiers sensitivity
(see 8.1.21)
, increase the head unit
volume and
repeat the bit Ten calibration procedure
as detailed in the following chapter 9.
Head unit input-level instrument check.
You will need an oscilloscope for this instrument check.
- Connect the head unit output to the oscilloscope.
- Play track 1 of the
bit Ten
CD.
- Set tone, fader and balance controls and
the equalizer (if any) to zero (flat).
- Turn on the car.
- Adjust the volume control so that the oscilloscope shows
a sine wave with slightly cut peaks, as shown in the figure.
- Note the volume used by the head unit. It must be left in this position
for the following operations.

How to setup the Master high-level main inputs.
You can assign any processor input channel the identifying name of the signal coming from the source.
The available names are:
FL
(Front Left Full);
FR
(Front Right Full);
RL
(Rear Left Full);
RR
(Rear Right Full);
FLTW
(Front Left Tweeter);
FRTW
(Front Right Tweeter);
FLW
(Front Left Woofer);
FRW
(Front Right Woofer);
Sub L
(Sub Left);
Sub
R
(Sub Right).
The
bit Ten
will use these names to reconstruct a full range signal coming from an OEM source with a dedicated
multi-channel amplifier and assign the corresponding signal to the respective analog output.
