Earthquake Sound's PA-600 can be used in Stereo Mode as two separate power amplifiers, each capable of driving loads down to 2-ohms. Each channel operates independently and has its own input connectors, sensitivity level controls, signal indicator LEDS, limiter circuitry, fault protection circuitry, power amp, and speaker outputs.
