3.8.2 Parallel-Mono Operation
Parallel operation of the two channels together.
The output terminals of the two channels are configured in parallel using an
internal relay. The (single) load is connected either to the output of channel A(C)
or to that of channel B(D) (as if in stereo). While the total output of the amplifier
remains the same and the output voltage level is also the same as in stereo oper-
ation, the minimum impedance that can be connected is reduced by half due to
the fact that current capability is doubled. Only channel A(C)-Input is active.
NOTE: For Parallel-Mono Operation, to prevent damage of one SPEAKON
connector and to reduce loss of power because of contact or cable
resistance, it is highly recommended to wire speaker loads using SPEAKON
connector with all contacts connected.
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
(+/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-Bridge 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 suppli-
ers/personnel. All cabeling or rewiring work must be carried out by quali-
fied personnel.
