DESC: . An unregulated Class A/B power supply allows the amplifier to really pour on the power in 2-ohm operation. All this power is at your command with variable crossovers, high- and low-level inputs, and variable bass boost. Fast-acting protection circuitry guards against short-circuits, over-voltage, overheating, or wiring mishaps. Gold-plated RCA input and output connectors insure maximum conductivity and resistance to corrosion. High 22kOhm input impedance lets you link multiple amplifiers in a single signal chain without having to use signal-robbing splitters.
