1000w Subwoofer Amplifier

The Dayton Audio SA1000 is a freestanding, high-power subwoofer amplifier designed for the DIYer, installer, and systems integrator. This unique monaural subwoofer amplifier delivers the raw power of a pro-sound amp, but with the features and flexibility of a dedicated subwoofer amplifier.

The Dayton Audio SA1000 is a freestanding, high-power subwoofer amplifier designed for the DIYer, installer or systems integrator. 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 SA1000’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 SA1000 with clean and controlled output. From an application standpoint, the SA1000’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 your 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 systems. 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 SA1000’s subdued brushed black aluminium 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.
