2.4 Connecting the inputs
The input/split connections are performed by
means of two 3-pin, XLR-type and two
“P10”- type connectors, located on the rear
panel. The connection orientation is:
Pin 1 - Ground.
Pin 2 – Positive (phase).
Pin 3 – Negative (counter-phase).
The fact of finding XLR-type connection cables on
devices or cables does not mean your connections are correct.
ALWAYS CHECK THESE DETAILS VERY CAREFULLY
The figures on the following pages show the basic diagram for the connections on
the rear of your amplifier in a sound system.
It is important on a stereo system to connect the mixer L channel to the amp
input 1, and the mixer R channel to the amplifier input 2.
The same precaution should be taken for connecting the speakers. The speakers
located on the right side of the stage should be connected to the right channel
(OUTPUT 2), and those of the other side to the left channel (OUTPUT 1).
The speaker polarity is also important. The speaker positive should be connected
to the amplifier (+) positive terminal, and the speaker negative, to the amplifier (-)
negative terminal.

amplifiers contain
balanced inputs and can be
powered either by balanced lines
or not, according to the figures.
You can connect up to two 8 Ohm speakers
or cabinets in parallel per channel, or only
one 4 Ohm speaker or cabinet per channel. If
you don’t respect these limits, you can
overload your amplifier and void the warranty.
