Speaker Calibration
The calibration procedure allows
you to adjust the volume level of each
speak er in turn until they are all equal.
This will give you the best Home The-
ater performance. You should only do
this calibration when you are sitting in
your usual lis ten ing/viewing position.
Preliminary: Play a movie and
adjust the volume for a comfortable
listening level. The volume of the cali-
bration test noise is linked to the setting
of the main volume control, so if the
test noise is too quiet, turn the main
volume up a little and retry.
1. Use the OSD to navigate to
the SPEAKER CALIBRATION
menu.
2. Press the remote's joystick
down to turn on the noise

buttons. Adjust each speaker
in turn until they are all equal in
volume.

times for each speaker until
you are satisfi ed they are play-
ing at the same level.
4. Press the joystick-up to return
to the top of the menu, and

you have set here, that is, they will still
be playing as loud or as quiet as each
other.
The Dolby Digital, Dolby Pro Logic
and DTS soundtracks are designed to
