3.6 Mode Selector
The switch on the rear panel changes the operating mode.
WARNING!
Always turn off the amplifier before making changes on the Mode Selector.
When the amplifier is switched on again, the selected mode will operate.
3.6. Stereo Operation, Two Channel Operation
Two fully independent amplifier channels (normal operating mode).
3.6.2 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, three identical loudspeakers are to be
operated with the same power.
