Constant voltage loudspeakers

The power amplifier can drive 100 V constant voltage
loudspeakers at full power (100 V) or half power (70 V).
Connect the loudspeakers in parallel and check the
loudspeaker polarity for in-phase connection. The
summed loudspeaker power should not exceed the
rated amplifier power.

Low impedance loudspeakers

Connect low impedance loudspeakers to the 8 Ohm/0
terminals. This output can deliver the rated output
power into an 8 Ohm load. Connect multiple
loudspeakers in a series/parallel-arrangement to make
the combined impedance 8 Ohm or higher. Check the
loudspeaker polarity for in-phase connection.
