calibration procedure

- insert the “TEST SIGNAL DVD” if the
head unit in use is a Dolby Digital (AC3)
“Audio Car Theatre 5.1” featuring
analog outputs, or an analog audio
system featuring a central channel.
Remark: if the source used is not
equipped with a CD player, and
only features a USB port, proceed as
described below.
1) Copy the Wav format tracks from the CD
to the USB storage device.
2) Copy the mp3 format tracks from the
folder located inside the setup CD on
the USB device, in case your player is
not able to play Wav formats.

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.
