This switch sets the AC voltage line of your country (usually it is set by factory and isn't necessary to
change it). The 115V setting is for mains line in the range of 105-120V~ and 230V setting is for mains line
in the range of 210-240V~.
WARNING: an incorrect setting of AC LINE VOLTAGE could damage seriously the internal
electronics!

This is the air vent for the amplifier’s cooling. It is important to keep all the air vents always free from
objects and dust for the proper internal air ventilation.

This is the jack connector that accepts the amplified signal from the mixer unit. Use always the supplied
power cable to connect the speaker and note that the impedance of each speaker is 4 ohm, this means
that only one speaker can be connected to each MIXER SPEAKER OUTPUTS.
The JACK power input is wired as follows:
