3.8.3 Mono-Bridge
One-channel mono bridged operation.
The second channel processes the same input signal, but with reversed phase.
The (single) load is connected between the two positive channel outputs
(1+/2+) using a suitable connected SPEAKON connector. While the total output
of the amplifier remains the same, both the available output voltage and the
minimum impedance that can be connected are doubled, as compared with
stereo operation. Only Channel A(C)-Input is active – turn the volume on
Channel B(D) down to zero.
WARNING!
In Mono-Bidge mode RMS output voltages are as high as 230 V. Wiring
to the speaker loads must conform to NEC Class 3 safety standards or its
equivalent that meets all national and local electric codes.
All customer specific cables may only be manufactured by qualified
suppliers/personnel. All cabeling or rewiring work must be carried out by
qualified personnel.
3.9 Wiring
