AudioSource AMP series amplifiers are designed for home and commercial audio distribution systems where high quality sound, flexibility, and reliability are essential. The AudioSource AMP 310 delivers 150 watts of stereo power and 450 watts of mono power at <0.1% THD. All AudioSource amps – AMP 102, AMP 110, AMP 210, and AMP 310 are rack-mount ready, full bandwidth capable, bridgeable for incredible mono power, and feature two zones of output with A/B or A+B speaker selection, providing a repertoire of flexible configurations. They boast a robust power supply and bipolar output devices. Front panel diagnostic LED displays show clipping to prevent over-driving your speakers. With second source override our amps automatically access secondary sources such as MP3 players, satellite radio, PA systems, paging, game consoles, phone calls or even doorbells. Speaker level inputs add another dimension to the usefulness of these fine amps; allowing for installation where only speaker wires are present to carry the signal information. For high power applications, the AMP 210 and AMP 310 are designed so users can set a safe maximum level using the rear panel master level controls, then make fine adjustments on the front panel. All AudioSource amplifiers are easy to install and are torture tested during development to ensure years of use.
