Frequently Asked Questions

What is a wireless volume controller?
A wireless volume controller lets you adjust your car audio amplifier volume from a battery-powered knob anywhere in the vehicle, without running analog control wires. The WVC communicates with a base station mounted near your amplifiers.
What is the wireless range of the WVC?
Up to 500 feet of line-of-sight range with the included antennas. For builds with heavy sound deadening, metal enclosures, or other RF obstructions, upgraded 6 dBi or 8-9 dBi external antennas are available to extend range and improve reliability.
How is the WVC knob powered?
The knob has a rechargeable internal battery, charged via USB-C. A full charge lasts several days of normal use.
Does the WVC work with the RTC Rotary Touch Controller?
Yes. The WVC supports RTC core features including volume, voltage monitoring, and IDS (Mute/Limit) modes. Full RTC audio visualization and temperature features require WVC-PRO.
Can I use multiple WVC knobs with one base station?
Yes. Multiple knobs can be paired to one base station through the AuralSync app for multi-user control or installs with more than one control point.

Why use a wireless bass knob?

In general, we believe that traditional bass knobs with long RCA runs hurt your system, regardless of manufacturer. Yes, there are quality differences between brands, but the fundamentals are the same. They're all fighting the same uphill battle.

Traditional knobs sit inline with your RCA cables between the source and amplifier. That means your audio signal is running 15-20 feet through the car, picking up noise from the alternator, ignition system, fuel pump, and whatever else is along the way.

Even quality shielded cables, or the RJ11 style knobs that come with your amplifier, can't fully stop it (we've shown this in test videos). And the longer that run, the better your chances of noise creeping in.

Then the signal passes through a mechanical potentiometer. It works fine at first, but those contacts wear out over time as you twist and turn the knob. You start getting scratchy adjustments, channel imbalance (yes, one side can wear out faster than the other), and intermittent cuts. Temperature swings speed that process up as materials expand and contract. We've all dealt with it.

This is why we built what we believe is a superior bass knob, the WVC (Wireless Volume Controller).

The audio signal cable stays short and controlled right at the amplifier. The wireless knob only sends control data, not audio, so interference never touches your music.

We also use the best available components on the market, which adds real functionality. The WVC doubles as a line driver, delivers 0.00045% THD+N, and 110dB SNR. Compare that to your noisy RCA bass knob that's been picking up EMI the whole time.

No pots to wear out. No cables picking up noise. No compromise.
