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 parallel connected 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

- *Dynamic power indicates the actual power this amplifier will deliver to the woofer under normal operating conditions. While the FTC power rating indicates power available on a continuous, long-term basis, subwoofers do not rely on that type of power. Instead, the amplifier is called upon to deliver large, short-term peaks of power to be able to support the wide dynamics required by today’s digital music and movie formats. In addition to the required FTC power rating, we’ve provided the dynamic power rating as a better indication of the product’s true performance.
