The first power ON
The mains switch is located at the bottom left hand rear
side of the jukebox. In position ‘I’ jukebox and amplifier
are switched on. The amplifier is now in STANDBY
MODE:
The yellow ‘Low Level LED’ lights.
The ‘Low Level’ circuit detects low music parts and pau-
ses. It effects the AVC circuit not to raise the audio level
in music pauses. So disturbing noises will not be heard.
This LED may light for short times during play.
The yellow ‘Mute LED’ lights (on the power amp board,
only visible after lifting up the pre amp board). It indicates
that the amplifier is muted.
To avoid power on and other noises, the amplifier output
will be switched on only during play.

Pre-settings for volume, bass, treble
After power on of the jukebox or after pressing the button ‘preset’ the levels of volume, bass and
treble will be set to basic values. These values can be set with different binary DIP switch combinati-
ons. The switches are located on the amplifier pre amp board. You can find the recommended set-
tings on the amplifier cover.
