Depending on the individual application, the amplier can be used in dierent operation
modes:
Stereo mode
Both power amp channels operate independently of each other, each input (A
and B) is amplied by one channel, speakers are connected to both channels,
the volume for both outputs can be controlled separately.
Parallel mode
The two amplier channels receive the same input signal from channel A and
loudspeakers are connected to each amplier. The volume is controlled via the
control knob for channel A.
Bridged mode
Both power amp channels are internally wired for providing double the output
power. Only the signal from input A is amplied, speakers are only connected to
the accordingly labelled output. The volume is controlled via the control knob
for channel A.
On each output of the amplier, the overall impedance resulting from the individual impe‐
dances of the connected speakers must not fall below the minimum allowable impedance of
the amp's output. If you want to connect multiple speakers to one amplier output, note the
following:
