Special pre-amplifier functions
Pre-amplifier settings which seldom need to be changed
are controlled using a special function menu. The
following special functions are available:
• Balance setting (BALANCE)
• Tone control, bass (BASS)
• Tone control, treble (TREBLE)
• Tone controls, On / Off (TONE)
• Volume-dependent tone control On / Off
(LOUDNESS)
Note:
(only for systems including the DD 820 M decoder)
The special functions which are described in the next
section are functions of the analogue stereo pre-amplifier
in the PT 820 M. They are only effective when the sur-
round decoder is switched off, i. e. in direct stereo mode.
In surround mode these settings are adjusted on the
DD 820 M.
Direct stereo mode is indicated on the screen by the
'DIRECT STEREO' symbol.

Balance function
Explanation:
The ‘Balance’ function is used to adjust the balance in
level between the left and right channels, e. g. in
situations where the speakers are not set up sym-
metrically.
Operation:
To change the balance setting press the remote control
buttons in the sequence stated above. The screen
displays the current balance setting of the pre-amplifier,
e. g.
' BAL LR 0 BAL LR 0 BAL LR 0 BAL LR 0 ' = stereo centre neutral
The current setting can now be shifted left or right in
discrete steps using the
    or     button.
Adjustment range:
' BAL L 63 BAL L 63 BAL L 63 BAL L 63 ' (stereo centre fully to the left)
to
' BAL R 63 BAL R 63 BAL R 63 BAL R 63 ' (stereo centre fully to the right)
Any change takes effect immediately.
Note:
If the stereo centre is adjusted to any non-central
setting, this is displayed on the screen briefly following
the volume value every time you adjust the volume, e. g.
'
VOLUME VOLUME VOLUME VOLUME 27 27 27 27 L L L L ', i. e. stereo centre offset to the left (L).
