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 4Ω OR 8Ω SPEAKER SYSTEMS (only PAM-120A)
CONNECTING HIGH-VOLTAGE DISTRIBUTED SPEAKER SYSTEMS
Total rated input of up to 120W (PAM-120A) or 340W (PAM-340A) or 480W(PAM-480A)
When connecting conventional 4Ω or 8Ω speaker systems, connect the speaker’s positive (+) side to the
terminal labeled 4. Connect the speaker’s negative (–) side to the terminal labeled COM. See illustration
below:
When connecting a high-impedance speaker system in parallel, you can connect speakers with a total
rated input of up to 120W (PAM-120A) or 340W (PAM-340A) or 480W(PAM-480A).
