4 - CONNECTION TO THE MAINS

First, it is essential to ensure that the main voltage corresponds to the
apparatus voltage. It is not advisable to connect and disconnect the
mains wire without first making sure that the switch is in its OFF position
in order to avoid bothersome noises.
CAUTION: the connection to any other voltage different from the one specified
can damage the amplifier immediately.

5 - CONNECTION OF THE LOUDSPEAKERS

The loudspeaker system should be connected to the Terminal connectors ensuring
2
that the polarity is correct. It is very important to use a cable of 1.5mm section
(minimum) in order to maintain the high features of power and quality these units
provide. You must know the impedance of the Line before switching on the amplifier.
The minimum impedance for channel is 64 Ω (in PA300TL) and 32 Ω (in PA600TL).
The amplifiers can work with lower impedances but the Protection circuit will start to
work as it will try to get the maximum power of the amplifier.

6 - PRE-AMP CONNECTION

The input enables connection through XLR-
3. The amplifiers incorporate balanced
input for a high rejection of parasites
generated by long signal cables or
proximity to electric wires or other sources
causing them.
