Rear Panel Layout
Figure 1: Rear panel of Moon 760A Dual-Mono Amplifier
The rear panel will look similar to Figure 1 (above).
Each channel has one balanced (differential) input
on an XLR connector and one unbalanced (single-
ended) input on a RCA connector. There is no
switch to toggle from balanced mode to single-
ended mode. You may operate the amplifier in
either mode, but only one mode at one time for
each channel. When you’re using the balanced XLR
inputs, you must first remove the factory
installed “dummy” XLR jumpers (see figure 2
below) from the back panel XLR connectors and
store them in a safe place. These jumpers are
required ONLY when using the single-ended RCA
inputs. If you decide to switch to single-ended input
mode, you must reinstall the XLR jumpers (between
pins 1 and 3) exactly as show below:
Figure 2: XLR connector without and with jumper accessory
There are two pairs of heavy duty gold-plated
speaker binding posts for each channel to
accommodate bi-wiring. They are each labelled
“Right Speaker Out” and “Left Speaker Out”.
The lower left section has an RS-232 input on a DB9
connector. To the right of this connector are two 12
Volt triggers, each on a 1/8” mini-jack; one input
and one output, the latter for use in the event that
wish you to “daisy chain” a second power amplifier
on the same trigger circuit. The lower right section
has from left to right; the “AC Fuse” socket cover;
the power “main switch”; and the “AC Input” IEC
receptacle for the power cord.
