The ARC 1000.2 is a two-channel amp rated to produce 500 watts per channel or a single 1000-watt channel into a 4-Ohm load. All amplifiers feature fully balanced differential inputs to reject common electrical noise and allow for connectivity to OEM amplifiers. Speaker level input adapter plugs attenuate the signal from a factory amp by to simplify OEM integration. Each pair of channels has an adjustable sensitivity control. Multi-channel amps include a source selection switch to negate the need for Y-Cables. All three amplifiers include dual DC offset and signal detection remote turn-on detection circuits.
