The SDA-100 is a warm sounding, cool-to-the-touch, digital subwoofer amplifier. It includes both low level (fixed signal) and high level (already amplified) inputs. This allows the SDA-100 to be connected in surround sound rooms as well as stereo only rooms where a dedicated LFE (low frequency effects) output is not available.
The SDA-100 is included with our HD-IWS10 In-wall subwoofer and S80 subwoofer. Unlike subwoofers with built-in amplifiers, the SDA-100 is best placed with your other AV equipment requiring only standard speaker cable to connect to your subwoofer.
