duction Dynamics A3 Internal Class AB Subwoofer Amplifier

The A3 subwoofer amplifier is designed to integrate with audio and video pre-amplifiers and receivers that have their own built-in low-frequency crossover circuits, typically containing optional crossover frequency settings such as the ID1 series and SW series subwoofers. If the crossover frequency is selectable, the recommended setting to use is 80 Hz with the subwoofer connected in reverse polarity. Harmonic distortion is < 0.05% (@ 1kHz 1 Watt). Output load is 10 K ohm (2.5 min). Level Controls: +/- 19dB w/fixed 1/2 dB steps.

This product has a patented non-distorting frequency-selective excursion limiter.
