Connecting to Additional Power
Amplifiers or “House” Systems

To yield 3 or 4-zone mono or 2-zone stereo, the jukebox
may be connected to an additional power amplifier. To
do so, leave the amplifier inside the jukebox connected
to channels 1 and 2. The additional amplifier should be
connected to channels 3 and 4, powered by the signal
available at the EXT output RCA jacks. Volume will be
controlled via the IR Transmitter.

If the jukebox is to be connected to a House system that
will provide all of the amplification

and

volume control,

the House system may be fed with either the INT or EXT
output RCA jacks. After connecting to the house system,
set the Pre-Amp output to the desired maximum level
via the jukebox volume control. Then, disable the
jukebox volume control by accessing VCU Setup in the
Service Mode and unchecking the appropriate
channel(s). See the

Network Setup, Jukebox Operation,

Operator Setup Screens Manual

for details.

NOTE:

It is highly recommended that the “Fixed” output

or the direct output of the Core NOT be used to drive the
House system, unless that system contains ground loop
elimination circuitry and audio processing that will
compensate for a variation of signal level from one
selection to the next (AVC). These features are built into
the Pre-Amplifier, and they appear at the “INT” and
“EXT” outputs.

Connecting a Paging Microphone

The Advanced SyberSonic Pre-Amplifier can accept
virtually any paging microphone. Pictured below are
wiring diagrams for the most common paging kits. The
necessary connector is included with a paging kit. To
use other paging kits, you will need to acquire one (1)
Amp part number 640250-4 housing (RMC P/N ST-
11244) and four (4) Amp part number 640252-1
contacts (RMC P/N ST-11245) or equivalent.

Connecting a Paging Microphone

The paging system works by either sensing audio on the
signal line, or by grounding pin 3 (switch). Whatever
microphone is used, it must have some kind of switch to
mute the audio when not in use.

Set the microphone gain switch to “LOW” and the gain
control at midpoint. Press the talk button on the
microphone and speak into it. The “Status” LED on the
amplifier should blink and the microphone signal should
be heard in the speakers. Adjust the microphone gain
control to the loudest level you want the location to be
able to use. If more gain is necessary, turn the
microphone gain switch to “HIGH”.

CAUTION: Be sure the gain control is turned down
to avoid speaker damage from acoustical feedback.

Refer to the amplifier settings for adjusting which
channels hear paging, the music level while paging, and
the length of time before the music comes back up.
