Connecting the 850P Preamplifier & Controller
Figure 1: Connecting the MOON 850P Preamplifier (bottom) and 850P Controller (top)
There are three (3) connections that must be made
between the MOON 850P Preamplifier’s chassis
and its separate controller chassis as shown above
in Figure 1; First, using one of the two supplied 4-
pin XLR cables, connect the end with the male pin
socket to the plug labeled “DC Power Output Right
Channel” located on the rear panel of the controller.
Connect the other end of the cable, with the female
socket, to the plug labeled “DC Input R” located on
the rear panel of the preamplifier. Next, using the
other 4-pin XLR cable, repeat the same process
between “DC Power Output Left Channel” and the
“DC Input L” socket. Finally, using the supplied 8-pin
Ethercon cable (both ends are identically
terminated), connect one end to the plug labeled
“Communications Output 1” located on the rear
panel of the controller. Connect the other end of the
cable to the plug labeled “Comm” located on the
rear panel of the preamplifier. You will notice that
there are two sets of each output connector on the
controller, however only one of each is required to
operate this preamplifier; the other connectors are
for possible future use with other components. Do
not attempt to modify the lengths these cables –
they are specifically designed for optimal
performance.
Connect the supplied AC power cable to the IEC
receptacle, located on the rear panel of the
preamplifier’s controller chassis. Ensure that the AC
wall outlet you use has a functioning ground. For
the best sonic performance, it is preferable that you
plug your 850P preamplifier directly into a
dedicated AC outlet and avoid using an extension
cord.
The MOON 850P is equipped with our M-Octave
Damping system, whereby the main audio circuit
board is coupled to the chassis using an 8-point
floating suspension that is designed to eliminate
distortion caused by the “Microphonic effect” of
airborne vibrations. All audio connectors are directly
mounted to this main audio circuit board. As a
