Description

The Monolith™ M3100X features high quality, class AB amplification and is the perfect amplifier to upgrade your amps in a receiver, handle height/effects channels in a larger system, or to be the backbone of a home theater system in smaller rooms. The M3100 is a three‑channel power amplifier that delivers 90 watts per channel into 8 Ohms (all channels driven) with less than 0.02% THD and a signal to noise ratio greater than ‑100dB. Hook up is a breeze by utilizing either the unbalanced RCA inputs or unbalanced XLR inputs make it easy to connect to any receiver or pre/pro. The Monolith M3100 multi‑channel amplifier combines power and performance to deliver high quality music or home theater sound quality in any application.
