Plinius Audio SA-103 manual Rca Stereo, Rca Bridged Mono, Xlr Stereo

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.

Now turn the ACS switch fully clockwise then two positions counter-clockwise so that it is in the XLR Stereo position. It is now safe to switch on your amplifier.
