Outlaw Model 5000 Differential-sensing RCA input circuit designed to reject input hum Independent power supply rectification for each of the 5 channels, to ensure excellent isolation. Two pairs of 150-watt Toshiba bi-polar output transistors per channel for fail-safe reliability. Separate output protection relays for each channel, designed to disengage the speaker from the amp in the unlikely case of a short, or excessive DC offset. A modular audio channel design to ensure each audio signal is isolated from the other channels, from input all the way to output.
