Product Description

Different songs and recordings can have dramatically different bass levels. The DC Sound RSW-250 offers a convenient way to compensate without constantly adjusting settings on your amplifier or stereo.

Installed in the RCA signal path, the RSW-250 functions as a passive remote level controller, allowing you to regulate the signal being delivered to the connected amplifier.

Turn the knob up for stronger subwoofer output, or reduce the level when a recording has excessive bass. This makes the controller especially useful for subwoofer amplifiers, custom car audio systems, and installations where the amplifier is mounted in a trunk, cargo area, or another difficult-to-reach location.

The stereo design provides left and right RCA inputs along with corresponding RCA outputs, allowing the controller to work with standard 2-channel RCA connections.

Installation requires no complicated electronic setup. Connect your source RCA cables to the RSW-250, connect another RCA cable from the controller to your amplifier, mount the control within convenient reach, and adjust the level as needed.
