Connecting Speakers - Inter-m PAM-240A 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 low-impedance (70V/100V) speaker system in parallel, you can connect speakers
with a total rated input of up to 240W (PAM-240A) or 360W (PAM-360A).
10W
Total rated input of up to 240W(PAM-240A) or 360W(PAM-360A)
For example, if you are connecting speakers with a rated input of 15W, you can connect up to 24
speakers in parallel, as shown below:
15W
WARNING: Extreme care must be exercised when connecting low-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.
