Connecting Speakers Connecting Speakers
(USA/CANADA & Associated Version)
Before connecting speakers disconnect the AC power cable. Make certain that the total impedance is not less
than the rated impedance indicated.
For 4Ω low-impedance speakers, connect in parallel, with the negative (-) connectors to the COM terminal and
the positive (+) connectors to the 4Ω terminal. See Figure 2-1 below.
For 8Ω low-impedance speakers, connect in parallel, with the negative (-) connectors to the COM terminal and
the positive (+) connectors to the 8Ω terminal. See Figure 2-2 below.
For high-voltage distributed systems, connect with matching transformer as per Figures 2-3 and 2-4 below. Be
certain that the total impedance does not equal less than the rated impedance.
FOR 25V TERMINAL
Be sure that total impedance is not less than rated impedance. Be sure that total impedance is not less than rated impedance.
FOR 70V TERMINAL
FOR 4Ω TERMINAL
