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 amplier 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 specic cables may only be manufactured by qualied
suppliers/personnel. All cabeling or rewiring work must be carried out by
qualied personnel.
