User manual

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. If you
connect more than one loudspeaker to an amplier output, please note the following:
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: 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.
