FIELD SERVICE MANUAL
12.8 Treble and bass control
You can control the sound with the knobs
bass and treble on the amplifier.
12.9 Automatic volume correction
The AVC sets CDs with different volume levels to an
equal level. The level of CDs with a high level will be re-
duced; the level of low-levelled CDs will be increased.
This control works rather slow to save the dynamic range
of the track.
You can enable the correction with the DIP switch “AVC”
(the 3rd swich of the 6 sw. group). Default is AVC disab-
led.
With the second DIP switch of the 6 sw. group you can
reduce the intensity of the volume correction.
12.10 Background Music - volume attenuation
In the BGM (Back Ground Music) mode the reproduction
volume will be reduced by a certain factor.
The signal “BGM” pin 1 plug brown of the SCC unit cont-
rols this function. You also can switch on “BGM” by
means of the DIP switch “BGM” for test purposes. The
RH bottom segment of the status display on the amplifier
indicates “BGM active”. You can adjust the volume atte-
nuation with the pot “BGM”, as long as it is active.
