Rear Panel Layout
Figure 1: Rear panel of Moon 880M Mono Amplifier
The rear panel will look similar to Figure 1 (above).
There is 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. When you’re using the
balanced XLR input, you must first remove the
factory installed “dummy” XLR jumper (see
figure 2 below) from the back panel XLR connector
and store it in a safe place. This jumper is required
ONLY when using the single-ended RCA input. If
you decide to switch to single-ended input mode,
you must reinstall the XLR jumper (between pins 1
and 3) exactly as show below:

There are two pairs of heavy duty gold-plated
speaker binding posts to accommodate bi-wiring.
The upper mid-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 mid-
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.
