Connecting Speakers
Before connecting speakers to your A-60/120 unit, be sure to disconnect the AC power
cable. Make certain that the total impedance is not less than the rated impedance
indicated.
For 4 speakers, connect in parallel, with the positive (+) connectors to the 4 terminal
and the negative (-) connectors to the COM terminal. See Figure below.
For high-voltage distibuted systems, connect with matching transformer to either 70V or
100V terminals, as per Figures below. Be certain that the total impedance does not equal
less than the rated impedance.
