RCA STEREO
Connect your preamplifier or input signal to the two RCA inputs at the top of the amplifier back panel.
Make sure you connect the red coded cable to the red RIGHT RCA input and the black (or white) cable to
the black LEFT RCA input. Also make sure the RCA connectors are a snug fit and are inserted all the way
in.
Next connect your loudspeaker wires to the output posts on either side of the rear panel. Connect your
right loudspeaker (ie the one on the right of you when seated in your normal listening position) to the right
output terminals, ensuring that the red positive (+) terminal is connected to the red terminal on your
loudspeaker. Do the same with the black or negative (-) terminals.
Now turn the ACS switch fully clockwise so that it is in the RCA Stereo position. It is now safe to switch
on your amplifier.
RCA BRIDGED MONO
This option configures your amplifier to drive one loudspeaker from one unbalanced signal fed to the red
RIGHT RCA input. In bridged mono mode the only input made to your preamplifier is to the red RIGHT
channel RCA input. The black LEFT channel RCA input is not connected.
Next your loudspeakers are connected to both positive (+) channel output terminals. So the positive red
connection on your loudspeaker is connected to the red RIGHT amplifier output, and the negative black
connection on the loudspeaker should be connected to the red LEFT amplifier output. DO NOT CONNECT
ANYTHING AT ALL TO THE NEGATIVE (-) TERMINALS. MAKING A CONNECTION TO THE NEGATIVE (-)
TERMINALS OF THE AMPLIFIER IN THIS MODE CAN CAUSE SERIOUS DAMAGE!
You can still connect two loudspeakers using the lower positive (+) amplifier output terminals. This is
explained in the bi-wiring section following.
Now turn the ACS switch fully clockwise then one position counter-clockwise so that it is in the RCA
Bridged Mono position. It is now safe to switch on your amplifier.
XLR STEREO
Connect your preamplifier or input signal to the two XLR inputs at the top of the amplifier back panel.
Make sure you connect the RIGHT XLR input and LEFT XLR inputs to the right and left outputs from your
preamplifier respectively. Also make sure the XLR connectors click into place.
Next connect your loudspeaker wires to the output posts on either side of the rear panel. Connect your
right loudspeaker (ie the one on the right of you when seated in your normal listening position) to the right
output terminals, ensuring that the red positive (+) terminal is connected to the red terminal on your
loudspeaker. Do the same with the black or negative (-) terminals.
