Dash mounted display and rotary / touch screen controller

The Rotary Touch Controller (RTC) puts complete command of your system right where you need it. Experience the perfect blend of precision engineering and intuitive design with this LF Audio companion.

Note: The RTC is a display / controller, it does not operate as a standalone device! You need to pair it with a WVC, SSA, or other LF Audio devices. The more devices you pair it with, the more sensor data / control options become available.

Key Features

Wireless Freedom – When paired with the WVC, control your audio levels from anywhere in your vehicle without running additional cables
Precision Touch Control – Smooth rotary action provides exact volume adjustments for the perfect sound level
Universal Compatibility – Works seamlessly with LF Audio products such as the WVC (wireless volume controller), SSA (Smart Signal Analyzer), WTH (Wireless Temperature Hub), and more!
Professional Grade – Built to LF Audio’s exacting standards for reliability and performance

Why You’ll Love It

Imagine adjusting your bass on the fly without taking your eyes off the road. Whether you’re cruising to mellow tunes or cranking up the bass for your favorite tracks, the RTC gives you instant control on your WVC without having to reach for your wireless knob. Professional installers and audio enthusiasts trust LF Audio for components that deliver consistent performance. The RTC continues that tradition with reliable wireless connectivity and smooth, responsive control that feels premium in your hand.

Perfect for Demos & Daily Driving

The RTC works alongside your existing wireless volume knobs, giving you the best of both worlds – a permanent in-dash bass knob AND a wireless handheld controller for vehicle demonstrations.

Customizable installation options

The gorgeous and ultra vivid 1.5″ AMOLED touch screen is surrounded by a 51.6mm aluminum housing that can be rotated. The rear housing is specifically designed to support in-dash / flat surface install as well as to perfectly fit standard 52mm gauge pods.

(WVC-PRO) Wireless Volume Controller – PRO

Adam — Fri, 06 Feb 2026 00:28:28 +0000

The WVC-PRO (wireless volume controller pro) is our top of the line remote volume control and data telemetry solution designed for the most serious bassheads!

For less feature rich versions, please see the WVC-LITE and WVC.

A “wireless bass knob”, voltmeter, and temperature meter all-in-one runs over a custom protocol on the 2.4ghz band (with dedicated 20.5dBm transmitter and 6dBi omnidirectional antenna) to give you long-range mission-critical style control over the volume of your system. The remote out line allows you to use the built in safety features to automatically turn off your amplifier if the voltage drops too low or the amp gets too hot.

You no longer have to endure the brunt of your monstrous ear-shattering system while giving demos. Step outside of your cabin and control your volume with this wireless knob!

Features

Wireless volume control	Our encrypted, long-range, channel hopping AuralSync™ protocol enables you to wirelessly monitor and control your system from up to 500 feet away with the stock antenna, and up to 1,000 feet with the external antenna!
Long Battery Life	Intelligent auto shut-off and power-saving modes ensure your bass knob can last for days between charges! The unit will restart within milliseconds to give you near instantaneous control after wakeup.
Wireless Over The Air (OTA) firmware updates	Receive new features wirelessly using built-in over-the-air (OTA) updates using the AuralSync ™ App.
Full Range	Flat frequency response and stable attenuation from 5hz to 30khz

15 Volt +/- RCA signal level support	Serious bassheads may run high voltage RCA drivers / DSP’s, which easily reach 15-volt peak-to-peak AC signal levels. Our controller reaches this level and adds even more overhead by supporting a full 15V +/- RCA line level!
Intelligent Drive System®	Automatically throttle your volume when your voltage drops too low or your temp is too high (PRO only)Video
Competition Mode	Automatically throttle your volume when your knob disconnects (battery dies, our of range, etc…)Video
Line Driver	Amplify incoming RCA voltage by up to +31.5 dB (15 V max) to overcome signal limit of some head units Video
