Mono Bridge Operation
In this operating mode, both channels of the power amplifier are interconnected. This
mode of operation provides a much higher output power but there is only one chan-
nel available. This is for example very useful when operating high-power subwoofers.
In mono bridge operation, only the input jacks (9 respectively 10) and the volume
control (6) for channel A are used. However, each channel is still secured with its own
protective circuit.
Put the switch SIGNAL SMART (11) to
the position "BRIDGE".
Connect the outputs of your audio
source (mixing table, equalizer, etc.)
with the corresponding input of the
power amplifier.
Connect the loudspeaker with the cor-
responding loudspeaker connections.
Examples for connection:
Here, the power amplifier is used to amplify the subwoofer. The impedance of the
connected subwoofer may not be below 8 Ohm in this operating mode.

Connect the output of the audio source
with the input jack XLR (9) CH-A IN
respectively with the input jack plug (10)
CH-A IN.
Connect the positive pole of the loud-
speaker with the red loudspeaker output
clamp marked with "CH-A OUT +" (13)
and the negative pole of the loudspeak-
er with the black loudspeaker output
clamp marked with "CH-A OUT –" (13).
Parallel Operation
If several loudspeakers are to be addressed with the same signal, use parallel oper-
ation. Only the input jacks (9 respectively 10) and the volume control (6) for channel
A are used. The output signal is connected to both loudspeaker outputs (12 respec-
tively 13).
Put the switch SIGNAL SMART (11) to
the position "PARALLEL".
Connect the outputs of your audio
source (mixing table, equalizer, etc.)
with the corresponding input of the
power amplifier.
Connect the output of the audio source
with the input jack XLR (9) CH-A IN
respectively with the input jack plug (10)
CH-A IN.
