The KA-1000-THX Subwoofer Amplifier from Klipsch is a full-featured Class D amplifier. It has a massive toroidal power supply that is capable of delivering 500W continuous into 8 ohms or 1000W continuous into 4 ohms. It can support two high performance subwoofers and has a left and right RCA pass-through.
Some valuable features include a front panel main power switch, a selectable signal-sensing auto-on/off circuit, and LED status indicators for crossover and level-control operation. Matching the look of Aragon home-theater components, finished in black with a machined aluminum front panel and knobs, the KA1000THX uses professional style NL2 Speakon outputs for the high current transfer of power to the subwoofer.
