FIELD SERVICE MANUAL
Three DIP-switches with the values 1, 2, 4 are provided
for each bass and treble. You can choose 7 different
steps of 3dB from minimum (-9dB) to maximum
(+12dB). Adding value of all switches set to "ON" gets
the total value.
The 0dB - 'linear' position of these switches is printed as
recommended factory setting on the amplifier cover.
NOTE:
If you change the DIP-switch settings while the
jukebox operates, new settings will be taken over after
having pressed the button ‘PRESET’ at the control ter-
minal or after a power off and on of the box.

Speaker connections
The speaker connector terminals are situated in-
side and on the back side of the jukebox.
To attain a good sound of the jukebox, take care
when connecting the speakers. Pay attention to
the following requirements:
The minimum impedance is 4
Ω
per channel!
The power output of each channel at a load of 4
Ω
is 170 W rms, i.e. the min. power consumption of a
4
Ω
speaker set should be 200 Watts.
All speakers must be connected with the correct polarity.
The speakers may be operated as desired in the
mode STEREO or 2-CHANNEL .
In STEREO mode the sound reproduction is al-
ways stereo.
In 2-CHANNEL mode it is possible to control the
volume of both channels independent to each
other. It allows to reproduce the sound in a second
room with different volume. The sound reproduc-
tion in this mode is only mono.
In 2-CHANNEL mode the volume of the speakers
connected to the normal terminals (R.H. channel)
can be controlled with the mode ‘VOLUME’ and the
volume of speakers connected to the screwing ter-
minals on the amplifier (LH channel) with the mode
‘BALANCE’. The preset volume can be set separately.
