The SDA-120 is a warm sounding, cool-to-the-touch, digital subwoofer amplifier that provides plenty of clean power to most subwoofers.  It includes both line level and high level (already amplified) inputs.  This allows the SDA-120 to be used in both surround sound and whole-house audio applications.  Watch this video to better understand your connection options for whole-house audio.

The SDA-120 is included with our HDX In-Wall Powered Subwoofer and Sub 80-LP Low-Profile Subwoofer.  Unlike subwoofers with built-in amplifiers, the SDA-120 is best placed with your other AV equipment requiring only standard speaker cable to connect to your subwoofer.  Alternatively, it can be placed near the subwoofer in cases where a line-level RCA connection has already been run to the subwoofer location.
