Versatile features

The amplifier's features include speaker-level inputs with signal-sensing amp turn-on, so it's ready to work in almost any system. A high-pass filter shapes the signal to fit your full-range speakers for their best-sounding output. You can also configure this amp for one-channel operation to power a subwoofer with up to 200 watts RMS. A low-pass filter and a bass boost EQ help dial in just the right amount of bass bump.
