Rear Panel Connections

The rear panel of the MOON 850P dual-mono preamplifier will look similar to Figure 3 (above). There are two
rows of connectors; the top row contains single-ended RCA inputs/outputs and the bottom row contains balanced
XLR inputs/outputs, as well as the three input connections from the separate digital controller chassis. There are
three (3) pairs of balanced inputs on XLR connectors (B1, B2, B3) and four pairs (4) of single-ended inputs on RCA
connectors (S1, S2, S3, S4). As a result of this preamplifier's dual-mono design, the left channel inputs are located
on the left side and the right channel inputs are locted on the right side.
This preamplifier is also equipped with a single-ended
monitor loop; the input and output connectors for each
channel are located on their respective sides of the rear
panel. The 850P has two (2) pairs each of balanced
The rear panel of the MOON 850P controller will look
similar to Figure 4 (above). It is equipped with full-
function bi-directional RS-232 port control and status
for custom integration or automation. This is located in
the upper-middle section and uses a DB9 connector.
Immediately to the right of the RS-232 port are two (2)
"SimLink" connectors labeled "in" and "out" on 1/8" mini
jacks. Please refer to the next section entitled SimLink
for more details. Your MOON 850P preamplifier has a
1/8" mini jack input for use with aftermarket infrared
remote control receivers.
located on the upper right section of the rear panel.
Across the lower section you will find the 3 pairs of
output connectors that are used for powering the
preamplifier chassis. To the right of these connectors
are two 12 Volt trigger outputs, each on a 1/8" mini-jack.

outputs are variable; One single-ended output is
variable and the other one is fixed, meaning that it
bypasses the volume control.
Finally, on the far right side are the "AC Fuse" socket
cover; the power "main switch"; and the "AC Input" IEC
receptacle for the power cord. All rear panel connectors
have been chosen because they provide the best
possible connections for your unit. A poor contact will
degrade the signal substantially, and plugs and sockets
should all look clean and free of dirt and corrosion. The
easiest way to clean them is to remove the cables from
their sockets and push them back in again. This
procedure requires that your preamplifier and the rest
of your components be completely turned off.
