Description
2 Pack DC Sound RSW-250 Universal RCA Bass Knob & Amplifier Level Control – 2-Channel Remote Gain Controller
Take control of your amplified audio system from the driver's seat with the DC Sound RSW-250 Universal RCA Level Controller. This compact inline controller provides convenient adjustment of the RCA signal being sent from your stereo to your amplifier, making it especially useful for controlling subwoofer volume and amplifier input level.
The RSW-250 installs directly in the RCA signal path between your head unit and amplifier. Its dual-channel stereo RCA input and output design works with a wide variety of aftermarket car audio systems, while the smooth rotary knob allows quick adjustments whenever your music or listening preference changes.
With its compact housing and included mounting bracket, the controller can be installed under the dashboard or in another convenient location within the driver's reach.
Key Features
🔊 CONTROL YOUR BASS FROM THE DRIVER'S SEAT – Quickly raise or lower the signal level feeding your subwoofer amplifier without having to access the amplifier itself.
🎚️ SMOOTH ROTARY LEVEL ADJUSTMENT – Easy-to-use control knob provides convenient manual adjustment for matching bass output to different songs and music styles.
🔌 INLINE 2-CHANNEL RCA CONNECTION – Connects directly between your stereo's RCA preamp outputs and your amplifier's RCA inputs for straightforward installation.
🚗 COMPACT REMOTE-MOUNT DESIGN – Small housing can be conveniently mounted under the dash or in another accessible location using the included mounting bracket.
🎵 UNIVERSAL CAR AUDIO COMPATIBILITY – Designed for use with most aftermarket head units, amplifiers, subwoofer amplifiers, and audio systems equipped with standard RCA connections.
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.
