Frequently Asked Questions

What is the difference between WVC-LITE and WVC-PRO?
WVC-PRO adds Remote Out with the Intelligent Drive System (automatic amp shutdown on voltage drop or overtemp), temperature monitoring via thermocouple probes, FFT and oscilloscope views through the RTC, competition mode, and RCA gain control. WVC-LITE covers core volume and voltage monitoring. Both support Smart Home / Matter integration with firmware 3.9.0 or later.
How does WVC-LITE's signal quality compare to competitors?
In independent third-party testing with a Quant Asylum QA403 analyzer, the WVC-LITE measured approximately 0.0005% THD+N at low frequencies, roughly 3.5 times lower than the Amp Lab competitor and 7 times lower than the Basshead Garage unit.
How many channels does the WVC-LITE support?
WVC-LITE is available in 2-channel and 6-channel versions. The 6-channel version supports up to six independent zones.
What knob options are available for WVC-LITE?
Single encoder, dual encoder, concentric dual (stacked), and quad (dual stacked concentric) configurations. Mix and match based on how many zones you need to control.
Does WVC-LITE support Google Home, Alexa, or Apple Home?
Yes. All WVC models (WVC, WVC-LITE, and WVC-PRO) support Home Mode with the Matter protocol on firmware 3.9.0 or later. Pair your WVC with Google Home, Amazon Alexa, Apple Home, or any Matter-compatible smart home app via the AuralSync app.

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.

You have absolutely no idea how bad you need one

You have absolutely no idea how bad you need one until you have it. Complete game changer, plus everyone you show it to will think it’s the coolest thing they’ve ever seen haha. I love it, 6 stars. Incredible product.

Works great! I love the weight of it and it’s the perfect size. I adjusted the sleep time so it doesn’t time out so often. Pretty easy to adjust everything. Moving up to the Pro dual knob next. Concentric for the win! Good job LF Audio!

Best Bass Knob On The Planet..

This is much more than a bass knob. After having and using a few days, I’m absolutely in love. I love it so much, I don’t think I can go on without. This is a must have if your a basshead like me…AKA All Black Tahoe on FB :~)

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!

Bass knob lite

Haven’t really played with it a lot yet but from me messing with for a few hrs I love it…don’t think I will ever go back to a regular bass knob again

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

Excellent product! WVC-LITE

I bought the wvc -lite and it’s awesome! Wireless is the way to go. Having the voltage displayed right in my hand is the best! Other than the $150 tariffs added on my purchase from my terrible government (Trudeau) I recommend this bass knob! Just like Marius said, I don’t agree with what’s happening between USA and Canada. Thanks again LF AUDIO!

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!!

Outstanding!

Fit and finish on this is really fantastic. As a small business owner, his customer service is almost impossible to replicate. It’s that good. I love this so much, I’m probably going to get one for my motorcycle build, just cause it’s so cool.

Wvc lite dual encoder

Absolutely the best accessory I have in my build. Head unit has push button volume control which I hated this is amazing and less noise. Never would have thought I would have spent this much on a knob but it's absolutely worth it 💯

The last bass knob you’ll ever want or need.

Amazing well engineered product surpassed all my expectations. I was on the fence for a while to spend that much on a bass knob but let me tell you it was well worth it once you see just how great it works. I was expecting some connection issues and lag but I was dead wrong. Power on and connection is practically instant and paired immediately out of the box. There’s no special process connecting and turning it on everytime you get in the car. Just leave the remote turned on and it goes to sleep after an adjustable timer. I just hop in the car, rotate the knob to wake back up and it’s ready to go before my amps can even power on. Battery life is great too I made it 10 days before needing the first charge. It’s just all around an incredible device and being wireless makes for a cleaner install and gives you more freedom hanging out at events. I can give demos from outside the car even from across a parking lot with full control and keep an eye on my voltage the whole time. Don’t let the price scare you just know you’re investing in the best bassknob there is and will never want to go back to bulky inline RCA knobs. Traditional custom bass knobs seem to start around 1/3 of the cost but when you consider functionality and convenience there’s no comparison. The cost is easily justifiable if you value the wireless convenience as much as I do. My setup is in a small 5 speed car so not having wires tied up around my shifter and E-brake is a dream come true. Any future builds will automatically be getting a WVC from the start and most likely some other genius creations that LF audio has in store for us.

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!
