6. Connections and Control Elements
Mono Channels
1) MIC input
This symmetric (balanced) XLR socket is intended for microphone connection.
For operation of a condenser microphone, a phantom voltage of +48 VDC can be applied
to the XLR socket.
Microphones or devices that do not require any phantom voltage may be
damaged by it (see phantom switch).
2) LINE input
Symmetric (balanced) 6.3mm LINE jack socket for connection of an instrument or device
with LINE output (keyboard, synthesizer, etc.). This socket can also be connected to an
asymmetric (unbalanced) mono jack. In this case, use short cables to avoid the danger out
outside interference as far as possible.
Only the MIC- or LINE socket of a channel must be used. Never use both
inputs of a channel at the same time.
3) TRIM control
The TRIM control sets the channel’s input sensitivity. The differently high signals of the individual channels can
thus be pre-amplifi ed and adjusted to each other. Turn the control to the left stop before connecting a device to
the input socket or disconnecting it.
4) Equalizer
Every mono channel is equipped with a 3-band equalizer (2-band equalizer ME502FP). The
HIGH, MID and LOW control can be used to lift or lower the high, middle and low tones of
the respective input signal. The control range is at +/-15dB (12kHz / 2.5kHz / 80Hz). The
control position “0” leads to neutral sound reproduction.
