Dayton Audio SA100 100W Subwoofer Plate Amplifier

Small but mighty! The Dayton Audio SA100 high performance subwoofer plate amp packs big-amp features into a compact chassis that is ideal for installation into cabinets that can’t accommodate bulky old-style amps. We made it small, but included everything that you need to connect the amp to your system and get maximum performance. Input/output connections are through your choice of either line level RCA connectors, or speaker level banana jacks. A stereo input signal is summed to mono and sent to the internal low pass crossover, which is selectable from 40 to 180 Hz; the input gain sensitivity is fully adjustable as well.

The SA100 also includes a phase reverse switch, which helps you to achieve the best acoustical match with the rest of your speakers. An Auto On/Off switch keeps the amp standing by, waiting for an input signal to turn it on. A large surface area heat sink is combined with internal overload, thermal, and short circuit protection so that you can expect years of reliable operation.
