Connecting Speakers

Before connecting speakers to your PA-920/PA-935 unit, be sure to disconnect the AC
power cable. Make certain that the total impedance is not less than the rated
impedance indicated.
For 4Ω speakers, connect in parallel, with the negative (-) connectors to the 4Ω terminal
and the positive (+) connectors to the COM terminal. See Figure 2-1 below.
For 8Ω speakers, connect in parallel, with the negative (-) connectors to the 8Ω terminal
and the positive (+) connectors to the COM 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.
