About: Klipsch KA-1000-THX THX Ultra2 Series Subwoofer Amplifier

The KA-1000-THX subwoofer amplifier is the powerful driving force behind the Klipsch THX® Ultra2 system. This model offers rock-solid dependability under the most demanding conditions and allows listeners to experience all the power, detail and emotion of their favorite music and movies.

Designed exclusively for use with Klipsch KW-120-THX subwoofers, the KA-1000-THX is a THX Ultra2 certified monoblock power amplifier capable of 500 watts continuous output into 8 ohms (a single KW-120-THX subwoofer, for example) or 1,000 watts continuous into 4 ohms (two parallelconnected KW-120-THXs). It incorporates front-panel controls for level, crossover frequency, phase, and room-gain compensation. The crossover can be bypassed to feed the amplifier directly from the subwoofer output of an A/V preamplifier, processor, or receiver. Line-level input and output connections are via gold-plated left/right RCA jacks. The amplifier has two parallel-wired speaker outputs with NL2 SpeakOn™ jacks for correct, secure cable connections.

Convenience features include a selectable signal-sensing auto-on/off circuit, a front-panel main power switch and LED status indicators for crossover and level control operation. Matching the look of Aragon home-theater components, the KA-1000-THX has a blackanodized, grained-aluminum front panel with aluminum control knobs. Premium electronic components are used throughout for sonic purity and reliability.
