Bridged mode

The two amplifier channels are internally connected in such a way that twice
the output power is available. Only the input signal from channel CH1 is ampli‐
fied and loudspeakers are connected only to the correspondingly marked
output. The volume is controlled via the control knob for channel CH1.
For each output of the amplifier, the total impedance resulting from the loudspeakers con‐
nected to it must not be below the allowed minimal impedance of the amplifier output. If you
connect more than one loudspeaker to an amplifier output, please note the following:
If the loudspeakers are connected in a series, the indivivudal impedances will be added up.
n
If the loudspeakers are connected in parallel, the reciprocal of the total impedance equals
n
the sum of the reciprocals of the individual impedances.
Example: If you have two loudspeakers with the same impedance, their impedance doubles if
they are connected in a series, their impedance halves if they are connected in parallel.
