The Coleman Audio CMC4 is a simple high-quality stereo monitor controller designed to calibrate your sub woofer according to the main speakers.
The CMC4 gives you the control of your sub woofer. Once a balance is set between the main speakers and the sub woofer the main level control will control both. There's also a mute switch to check your mix with or without the sub.
