Channel 1 has a talk-over circuit to improve the speech intelligibility. This circuit, which is triggered by the microphone signal from channel 1 (i.e. it is voice-activated), ensures that this signal overrides all others. The talk-over function can be disabled with the TalkOver switch on the front.
By default two output zones are available (master A and master B). These zones have a dual equalizer, balance and gain-control. In addition a maximum of four output modules (outputs zones) can be added. The volume of these additional zones is externally adjustable (with a potentiometer or an external regulation voltage).
Master A output is electronically balanced on XLR and unbalanced on cinch connectors. The balanced output makes it possible to use long signal-cables so that the amplifiers can be placed near to the speakers. Master B and the optional output zones are equipped with unbalanced cinch connectors.
