MOON W-8 Dual-Mono Power Amplifier
Rear Panel Layout
Figure 1: Rear panel of Moon W-8 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. In the event
that 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. In the event that 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 “Speaker Output 1” and “Speaker Output 2”.
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.
