Connecting the Amplifier
Input connections
The input connections of the amplifier should be made by connecting the signal from the signal
source, pre-amplifier or mixer to the balanced XLR input connections.
Next to every pair of input channel connectors is an operational mode switch provided. By means
of this switch, the operational mode of the amplifier can be selected. There are three different
operational modes available:
1) Stereo Mode:
This is the default mode how the amplifier is set in the factory, and will be the most
common used setting for most applications (Center position of the switch). When
both switches are set in Stereo mode, all the four amplifier channels work
separately, and amplify the signal which is available on the corresponding balanced
XLR signal input.
2) Bridge mono Mode:
In bridged mono mode, the power of two output channels is merged to deliver
double the power to one single 8 Ohm load. The mode selection switch should be
positioned in the Bridge position (Left position of the switch).
