The mixer amplifier can drive 70 V constant voltage loudspeakers.

Connect the loudspeakers in parallel and check the loudspeaker polarity for in-phase connection. The summed loudspeaker power should not exceed the rated amplifier output power.

You can use the Call Only output for 3-wire remote volume control override. You can also use this output as an extra zone where announcements can be heard, but not music.

Connect low impedance loudspeakers to the 4 Ohm/0 terminals. This output can deliver the rated output power into an 4 Ohm load. Connect multiple loudspeakers in a series/parallel-arrangement to make the combined impedance 4 Ohm or higher. Check the loudspeaker polarity for in-phase connection.
