The two amplier channels are internally connected in
such a way that twice the output power is available.
Only the input signal from channel CH1 is amplied and
loudspeakers are connected only to the correspondingly
marked output. The volume is controlled by the volume
control of CH1.
For each output of the amplier, the total impedance resulting from the loudspeakers con‐
nected to it must not be below the allowed minimal impedance of the amplier output. Con‐
necting more than one loudspeaker to an amplier output, please consider:
n If the loudspeakers are connected in a series, the individual impedances will be added up.
n If the loudspeakers are connected in parallel, the reciprocal of the total impedance equals
the sum of the reciprocals of the individual impedances.
Example: Using two loudspeakers which have the same impedance, the impedance doubles if
they are connected in a series, but it halves if they are connected in parallel.
