Bass Knobs
(9 products)Our bass knobs and remote level controls give you an easy way to adjust system level from the driver’s seat. They suit drivers who want quick control without reaching the amplifier or processor, but the right control depends on the gear and function you need.
Match the control to the signal path
A dedicated amplifier or processor remote works through that unit’s remote connection and controls its supported function. An inline RCA level controller adjusts signal level in the RCA path instead. The PAC LC-1 is a universal RCA remote level control, while the AudioControl ACR-U is a universal line-level controller. Do not assume an amp remote and RCA knob perform the same job. Match the control type, connection, and intended function to your setup.
Plan the knob location and cable route
Mount the control where you can reach it safely, without blocking vehicle controls or placing it near pedals. Route its cable away from sharp edges, moving parts, and hot surfaces. Leave enough slack for the control to be removed for service, then secure the cable so it cannot rattle or snag. Keep the knob’s purpose clear: a level control is for adjustment during listening, not a replacement for setting amplifier gain correctly.
- Amplifier or processor remote: Match the remote to the specific unit and its supported connection.
- RCA level control: Confirm the RCA layout and where the controller belongs in your signal path.
- Controlled function: Know whether the knob changes output level or another documented setting.
- Installation: Measure cable reach and choose a secure, accessible mounting spot.
Choose a control for your system
For a dash-mounted remote, compare the AudioControl ACR-4 with your compatible AudioControl equipment. The Wāvtech linkRC is another remote level control to consider when its connection and function suit your system. For a combined device, the Stetsom GAINCTL 4in1 title identifies a bass knob, voltmeter, and RCA converter.
