Rear Panel Layout

Figure 1: MOON MC-8 Rear panel

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. If 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 shown below

:

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 230V “AC Input” IEC

receptacle for the power cord, the “AC Fuse” socket

cover and the power “main switch”.
