The amp- Small but mighty! This high performance amplifier module 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, and the input gain sensitivity is fully adjustable as well. A phase reverse switch helps you to achieve the best acoustical match with the rest of your speakers, and an Auto On/Off switch keeps the amp standing by, waiting for an input signal to turn it on. A large surface area heatsink is combined with internal overload, thermal, and short circuit protection so that you can expect years of reliable operation.
