Product Overview
The PAC LC-1 brings a dedicated audio-level knob to an RCA-based car audio system. Install it between a receiver's preamp outputs and an amplifier's inputs to adjust that signal path from a convenient location. It is a straightforward option for a subwoofer amplifier when you want everyday bass-level adjustment without navigating the radio's menus.
This is a two-channel, inline RCA controller rather than a remote designed for one amplifier's proprietary control socket. It can also adjust a stereo amplifier feed. What it controls depends on where you place it in the signal chain: a subwoofer-only feed gives you subwoofer-level adjustment, while a full-range stereo feed changes that feed's overall level.

Why Choose This Product?
Choose the LC-1 when your goal is convenient level control in an existing RCA signal path, not an additional display or electronic processor. Its simple connection layout makes it useful when the amplifier has no suitable dash remote or when a system needs a separate control for one audio zone.
A level knob is not a substitute for amplifier setup. Set gains and crossover settings correctly before using any remote control for listening adjustments. Turning a knob cannot make an overloaded or clipped signal clean.
Installation & Compatibility Notes
- Connect the source's RCA output to the LC-1 input, then connect the LC-1 output to the amplifier input. Preserve left/right channel identification.
- Use it with line-level RCA signals. Do not connect speaker outputs directly; a compatible line-output converter is needed when the source provides only speaker-level audio.
- It does not plug into an amplifier's telephone-style or proprietary remote port.
- Allow room for the attached leads, plug bodies and cable bends, in addition to the housing dimensions. Mount clear of pedals, airbags, switches and moving trim.
Frequently Asked Questions
Can I use the LC-1 as a bass knob?
Yes, when it is installed in the RCA feed going to the subwoofer amplifier. It adjusts that feed rather than independently changing the bass in every channel.
Does it need 12-volt power?
No separate power or ground wiring is required for the controller.
Is this a bass-boost processor?
No. It is a line-level control, not an equalizer, crossover or bass-restoration processor.
Will it work with any amplifier remote jack?
No. Compatibility is through an RCA audio signal path, not the amplifier's remote-control connector.
Are full-length RCA cables included?
No. The short attached input/output leads are included; the patch cables needed for your vehicle's routing are separate.
Can it control full-range stereo speakers?
It can adjust the two-channel RCA signal feeding their amplifier. Plan the routing so you control only the channels you intend.
