Cables and Jumpers
Obtain two shielded audio cables long enough to reach between the input device (FM radio,
TV, tape player, etc.) and the amplifier accessory board.
This configuration requires all three jumpers supplied with the accessory board. Connect
these jumpers between:
1.
J9 (LEFT CH POWER AMP INPUT) and J14 (INVERTER OUTPUT).
2.
J13 (RIGHT CH POWER AMP INPUT) and J20 (RIGHT CH PREAMP OUTPUT).
3.
J11 (INVERTER INPUT) and J16 (LH CH OUTPUT).
Input Level Considerations
The background music input can accept a wide range of input levels. You can connect
speaker lines, aux. outputs or line outputs.
Stereo Background Music Input
Connect a stereo device as described here to provide background music from an external
source during periods that the jukebox is not playing a paid selection. The volume of this
music (generally lower than paid selections) is adjusted on the amplifier accessory board as
described on Page 9. The jukebox preamplifier settings are used for tone control. A device
connected to this input will not be heard during pages, or while the jukebox is playing a
selection.
WARNING: Be sure that the equipment you are connecting to
the Jukebox has an isolation transformer type power supply.
Equipment that does not have an isolation transformer can
damage the jukebox and/or create a shock hazard.
Input Connections
Connect the input cable from the music
source as follows:
1.
RIGHT CHANNEL J8 (RH CH BGM)
2.
LEFT CHANNEL J6 (LH CH BGM)
