Before connecting speakers to your PA-2000A/4000A/6000A 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 Ω low-impedance speakers, connect in parallel, with the negative (-) connectors to the COM terminal and
the positive (+) connectors to the 4 Ω terminal. See Figure 1 below.
For 8 Ω low-impedance speakers, connect in parallel, with the negative (-) connectors to the COM terminal and
the positive (+) connectors to the 8 Ω terminal. See Figure 2 below.
For high-impedance systems, connect with matching transformer as per Figure 3 below. Be certain that the total
impedance does not equal less than the rated impedance.
