Connect the speakers to the terminal block output connectors on the rear. Never turn on the ampli
fi
er when the
speakers are not connected to the outputs. When using the 4 Ohm output, you must connect speakers with a minimum
impedance of 4 Ohms (4 Ohms or more).
For 70V opera
ti
on, connect the speaker's posi
ti
ve input to the 70V terminal, and the nega
ti
ve input to the COM
(ground) terminal. Then connect the other speakers one a
�
er the other in parallel.

Since the PR-Series mixer-ampli
fi
ers have 6 output zones in 70V opera
ti
on, you can create separate audio
environments using up to six of the PR-Series’ outputs.
