TECTON POWER AMP SERIES
P.153.8.2 Stereo Operation, 2 Channel Operation
Two fully independent amplifier channels (normal operating mode).
3.8.3 Parallel-Mono Operation
Parallel operation of the two channels together.
The output terminals of the two channels are configured in parallel using an in-
ternal relay. The (single) load is connected either to the output of channel A or to
that of channel B (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 operation,
the minimum impedance that can be connected is reduced by half due to the
fact that current capability is doubled. Only channel A-Input is active. The chan-
nel B-Input is inactive – turn the volume of channel B down to zero.
This mode is useful when, for example, 3 identical loudspeakers are to be
operated with the same power.
3.8.4 Mono-Bridge Operation
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 using
a suitable connected SPEAKON connector. While the total output of the ampli-
fier remains the same, both the available output voltage and the minimum
impedance that can be connected are doubled, as compared with stereo ope-
ration. Only channel A-Input is active. A signal feeding channel B will have no
effect on the output. Turn the volume of channel B 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 equi-
valent that meets all national and local electric codes.
All customer specific cables may only be manufac tured by qualified
suppliers/personnel. All cabling or rewiring work must be carried out by
qualified personnel.
