JL HD RBC-1 For HD & XDM Amplifiers
Product Description
The HD RBC-1 is a high-precision wired remote level controller designed specifically for JL Audio’s flagship HD and XDM series amplifiers. Unlike generic bass knobs, the RBC-1 integrates directly with the amplifier's internal circuitry to provide a master volume control for the subwoofer or full-range output from the driver's seat. It features a high-grade rotary potentiometer housed in a compact, dash-mountable chassis, allowing for discreet installation. By connecting via a standard RJ11 cable, it enables the user to adjust bass levels on the fly to compensate for different music recordings or road noise without degrading the signal-to-noise ratio.
