Frequently Asked Questions

What makes WVC-PRO different from WVC and WVC-LITE?
WVC-PRO adds Remote Out with IDS (auto amp shutdown on voltage drop or overtemp), up to 3 thermocouple temperature probes, FFT and oscilloscope views via the RTC, competition mode, and per-channel RCA gain control. WVC and WVC-LITE cover core volume and voltage features. Smart Home / Matter integration is available on all WVC models with firmware 3.9.0 or later.
What is the Intelligent Drive System (IDS)?
IDS uses the WVC-PRO's Remote Out pin to automatically cut power to your amplifiers when voltage drops below your configured threshold or when a thermocouple reads over your temperature limit. It protects amps and batteries from damage without user intervention.
Does WVC-PRO work with Google Home, Alexa, and Apple Home?
Yes. Firmware 3.9.0 and later support Home Mode with the Matter protocol, allowing control from Google Home, Amazon Alexa, Apple Home, and any smart home app that speaks Matter. This feature is available on all WVC models, not just WVC-PRO.
Can WVC-PRO monitor temperatures?
Yes. WVC-PRO supports up to 3 thermocouple probes for real-time amplifier, speaker, and battery temperature monitoring. When combined with IDS, it can automatically shut down amps when temperatures exceed your configured threshold.
How many zones can WVC-PRO control?
WVC-PRO is available in 2-channel and 6-channel versions. The 6-channel version supports six independent zones, enough for front L/R, rear L/R, and subwoofer channels with individual volume control.

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.

Quad knob

Very impressed with this product and the support behind it. I ordered the wrong one. They offered to take it back. I’m just putting that one in the boat. Install went smooth. Only issue I had was I used a different usb cable that didn’t mesh. Lf got back to me with the answer on a Saturday night. I was impressed just by the box it came in. lol.

Another amazing LF Audio product

I upgraded from a 2 channel WVC lite to a pro version. I wanted the oscope and temperature monitoring features so I grabbed one when I found out they would be shipping out soon.

It’s already paid for itself by allowing me to see that I had a bad RCA cable between my PAC module to my subwoofer amp. One of the channels was getting an intermittent signal and causing my sub voice coils to cook when I had both channels going to my amp. The RCA cable was likely damaged because of how I had the WVC lite mounted…my pro is mounted much better so I don’t anticipate having any more issues.

After replacing the RCA cable all is good again and I’m getting a good clean signal to my amp. My sub voice coils are thanking me. Bass is loud and clean sounding again.

Expensive but worth it!

At first I laughed at people who bought it, but in the end I bought it myself, I don't regret it, the range of configurations of this bass knob is really interesting and surprising, the competition will not reach such a level in the next 10 years. I highly recommend it, but I regret one thing that I did not order 2 of these, one for home and one for the car!

LF audio bass knob

This is by far the best bass knob I’ve ever purchased might have been my second one but will be the last one I get for my setup 500ft of distance and it clears out wiring within eye sight

Amazing product.

Installation was straightforward and very easy. The knob and base are well built with a nice weight to them. All the extra built in features like the hu voltage, overall voltage, and osilscope make this an invaluable tool for dialing in your build. I highly recommend getting past the initial sticker shock and just go for it....worth every penny!!

Very awesome technology

I love my new wvc-pro I don't have a very large setup but still even with that it is awesome it's enhanced my bass experience by a lot by providing more RCA voltage while giving less distortion than anything I've seen making my bass louder and cleaner than it's ever been, Thank you I can't wait until I upgrade to see what it will do then. Only thing I have to criticize is the protective case that it comes with is impossible to get off and I understand it has tight tolerance to keep it save but I'd would like to take it out of the case sometimes. Also the knob function it's self works well most of the time and then I'm having episodes where I'm trying to turn the bass down and it's going back up and down at the same time while I'm rolling the bass knob down other than that it's been perfect and amazing for me the past week I've had it so far!

Just buy it, you'll love it!

I love the product and the support from LF Audio. I messaged him a few times, both before and after purchasing and always fast responses. I love the device and all the features, as well as the accessories it comes with. This will be great when competing and every day jamming. I compete alot and this will definitely help me with precise rolls for clamped classes. One cool thing is the knob itself is indented so you can feel each click while rolling for precision. Also has a fast and slow roll option for speed of the roll. I've only used it about an hour but so far I'm happy with the purchase and look forward to getting to learn more about it as time goes on, as well as future updates.

Best bass control I’ve ever had

While you feel it may be a little expensive compared to other companies. You have to remember the fact of all the added features you get and not only that the fact you get all these features through a very well built wireless unit. Loving this setup so far it’s been awesome can’t wait to get in the lanes with it! P.s. don’t mind the receiver mount I have wire management to finish yet.

Great people to work with

I have not used the wireless volume controller yet that they sent me to review but I have used the OG HPVM for the better part of a year and it’s fantastic. Plus this company is just great, the customer service has been outstanding. I always worry about updates with tech like this. A lot of companies abandon products either for new releases or they just aren’t interested in updates but not LF Audio, they update the software on the HPVM exactly how I would want. It seems like every few days there are updates. They also listen to ideas, so if you have an idea how to improve a product through a software update they will implement it if they can. I made a suggestion about something I would like to see be available on the HPVM and just a week or two later it was included in an update! LF Audio is innovating the future of car audio. I would not be surprised to see this company at the top of the game in a few years. I am happy to be involved in the little way I am by being able to test this equipment and to give the company an additional platform to be able to address the car audio community on my YouTube channel. They definitely have a life long customer with me!

Amazing technology, 100% worth every penny!

First of all, all of the R&D that has gone into this, as well as the owners transparency led me to spend my hard-earned money here instead of the cheaper options on the market and I 100% am glad I did!

This thing is functional, looks great and allows me to play my system remotely while I get more people into the vehicle for demos at shows.

Hands down the best knob I’ve ever owned/ran

After running through every knob in the game and having nothing but issues this breath of fresh air came along. Solid built, engineered to the moon with features no other knob ever has offered. Noticeable difference in quality over every other knob I’ve ever had from the minute I got it hooked up. Absolutely worth every penny. The range and quality are next level. 10/10 recommend

I want to buy a Pro version Bass knob for my Bass loving Honey to use in his car. Do I need to upgrade to the 9 dbi version? One knob is ok too? I don't want to buy the wrong thing. Any help would be appreciated. Thanks!

LF Audio

The antennas it comes with are great, only upgrade if he has a massive build and may want the anteanna placed on the roof at shows for max range.
