Connecting Speakers
Before connecting speakers disconnect the
than the rated impedance indicated.
For 4 low-impedance speakers, connect in parallel, with the negative (-) connectors to the COM terminal and
the positive (+) connectors to the 4
For 8 low-impedance speakers, connect in parallel, with the negative (-) connectors to the COM terminal and
the positive (+) connectors to the 8
FOR 4 TERMIN L
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 TERMIN L
Be sure that total impedance is not less than rated impedance.
