Power Amplifiers are the backbone of any good sound system. Today’s group fitness programs require quality amplifiers that will deliver maximum bass and good clean audible sound (whether driving 2 or 4 speakers). Room size, room acoustics, speaker capability, and speaker placement should be taken into consideration when selecting an amplifier. AV Now carries only quality amplifiers with warranties of three years or more. If there is a brand of Power Amplifier you want but don’t see here, just contact us!
