Advanced Subwoofer Amplifier

Ariatechnik’s AT 1K SA mono subwoofer amplifier provides nearly a kilowatt of clean, solid power to your home theater or music playback system. The amplifiers convenient freestanding or rack-mountable configurations make it an ideal partner for high-performance subwoofer speaker systems.


This unique monaural audio device delivers the raw power of a
pro-sound amp, but with the features and flexibility of a dedicated subwoofer amplifier. It can be configured for stacking with other audio components, and includes removable ears for mounting in standard audio racks (2RU). The AT 1K SA’s patented tracking down-converter power supply ensures headroom for instantaneous power needs and the amp stays cool, thanks to its high-efficiency design.

A Class-AB amplifier configuration provides the AT 1K SA with clean and controlled output. From an application standpoint, the AT 1K SA's low frequency parametric EQ enables you to boost or cut to custom-tailor the sound to suit the listening environment. Sophisticated soft clip circuitry provides cleaner transient peaks while protecting the subwoofer driver from over-excursion. The amp's switchable subsonic filter removes subsonic information from the signal, which tightens the low-end response of some subwoofer applications. On-board bass boost filters enhance LF performance while leaving the parametric EQ function available to address room modes, like cutting an excessively loud room resonance. The high-pass outputs provide a user the option to feed the signal back into their other audio components or a distributed audio system.

Manual, automatic on/off or triggered 12V input modes allow easy integration into automated systems. The stealthy pop-out knobs on the front panel make adjustments easy, while minimizing the risk of accidental disturbance. The AT 1K SA’s subdued brushed black aluminum faceplate allows the amp to blend cosmetically with any type of audio gear. Accommodates RCA line-level inputs, includes insulated binding posts for the speaker outputs, and accepts a 12V trigger via a 3.5 mm mini-jack.
