Connecting Speakers - Inter-m PAM-510 Operation Manual

Connecting Speakers

Connecting Speakers
Before connecting speakers, disconnect the AC power cable. Note the proper connecting terminals as shown
below. Make certain that the total impedance is not less than the rated impedance indicated.
- CONNECTING HIGH-VOLTAGE DISTRIBUTED SPEAKER SYSTEMS
When connecting a high-impedance(70V/100V) speaker system in parallel, you can connect speakers
with a total rated input of up to 25W (PAM-510) or 50W (PAM-520).

NOTE: Be sure that total impedance is not less than rated impedance. (See upper chart.)
WARNING: Extreme care must be exercised when connecting high-impedance systems, as potentially
hazardous voltages may be present at these terminals.
Do not install this equipment in a confined space with less-than-adequate ventilation.
