Wireless Mic Experiences with L1M2

Anyone out there have any experience with this wireless mic adapter (or something similar)? It’s intriguing because you can plug in a transmitter into your existing dynamic mic and its receiver into your mixer.

I don’t have any special long distance requirements, just tired of wrangling with cables. I’d never be more than 10 feet away from the L1, however, I still want quality sound from our Shure 58A Beta mics. Not sure if something like this would adversely “color” the sound. 

Original Post

In 40 years of gigging I have found that using a cable eliminates a lot of potential issues. If it doesn't work, you simply swap it out. Nothing against wireless, but a spare cable is cheaper and has a lot fewer points of potential failure. Just my two cents...

I agree with Mr. Hoon.

I don't believe I've had more than 2 or 3 wire failures in the last 50 years of gigging but numerous failures with wireless -- including a $1200 2-channel wireless system designed for recording video that has failed each of the last 3 times I've tried to use it -- which was very embarrassing when I did sound at the State Senate Candidate's forum last October.

But if you go wireless, you'd best buy the best system you can afford.  Or use the money to upgrade your microphone.  For the cost of the cheapest wireless system I'd attempt to use you could get a Neumann KMS105!

Totally get what past posts were saying. With the U3, I thought I’d would try it to see if I’d like it first of all.

Then, if it fails at a gig, I just unplug them and go back to cables since I’m using the same mics for wired or wireless. Anyway, something I need to think about more. 

I have a wireless Shure beta 58a, and have new ver based a problem with it. Call sweetwater music, ask for Matt South, he's my sales rep. He'll hook you up. 

Sweetwater music is awesome, customer service is awesome, delivery time is awesome and usually free shipping!

True, but if you go wireless always have a spare mic/cable if the need arises. 

Agreed. What intrigues me about this Xvive U3 mid wireless setup is the transmitter plugs into your dynamic mic where the cable would go and the receiver plugs into a XLR input of your mixer. It all runs on rechargeable batteries that last for 5+ hours. It simply replaces the XLR mic cable. So if it does go bad, you just have to replace it with a standard cable and your back up. 

Certainly not a high end system, but for 2 vocal mics in close proximity to our L1 and mixer, seemed like a reasonable solution.

I have had amazing success with the Shure QLXD.  Certainly not cheap, but top line wireless!  And you can use all the nice shure mic elements with it, including the condenser versions. 


I have tried so many in the last 5 years, and they all had severe drop out issues except the QLXD

Hi Pete,

If you try the Xvive Audio U3 Plug-on Wireless Microphone System, please come back and tell us how it works for you.

A few years ago I would have scoffed at the ideas I would:

  • Play a carbon fibre guitar for most of my acoustic gigs
  • Use a 16-pound, battery-powered portable PA for real gigs
  • Use a 12-pound amp profiler through a personal PA to replace all my guitar amps

I'm all set for wireless gear, but I'd be grateful to learn from your experience.


P.S. If anyone is interested, I've started a new discussion to talk about

What's changed for you in live sound?

I sure will report back @ST.

It may be a while since we are just about to move into our newly built house. The only thing negative I’ve heard so far is that it can be a bit noisy. I’m assuming an underlying hiss of some sort. That may be a deal breaker, but I’m going to see if I can try one out at one of the local music stores first. 

Regardless, I’ll report back here with any of my findings.

In the meantime, click here for a pretty comprehensive YouTube review of the U3 from Dec 2018. It’s 43 minutes long and goes into some aspects that I didn’t care about such as interoperability with an Xvive U2 unit. However, the reviewer nicely breaks the video into time slots so you can zoom past any topic you’re not interested in. 

Hi ST,

Interesting topic indeed, I just wonder if Xvive U3 wireless Microphone system can be use to connect XLR right and left of the T8S Bose mixer to the S1 Pro x 2 (left right) instead of the usual cable. Judging by the size of the transmitter (incidentally same as the receiver) and the fact that T8S XLR outputs are pretty close to each other, is that still possible?

Please find attached 2 file: one from the Xvive U3 user manual stating the dimensions and the other is simply picture of the units.

What do you think?

Hi Julian8023,

It looks like a tight fit. You might have to use a couple of short XLR cables between the T8S and the XVIVE U3 transmitters.

edit: Removed concern about access to the power switch because controls on the transmitter would probably be accessible.

It looks like the controls would be visible from the top.

Thanks ST, although there is a similar design unit with even smaller dimension - width wise: 1 inch and it’s square, but lacks of the mic/line switch. Because the idea is to use it as a substitute to the xlr (f) to xlr (m)or xlr (f) to trs (m), how crucial is the switch? Is the signal coming from xlr outputs of T8S a line or microphone level?

The other brand I’ve mentioned above is NUX B3 and here are some pics of it too..

@Julian8023 thanks for sharing I for about the Nux unit. It looks to be the same as the U3 except for the mic/line switch and some other exterior design differences. 

Its even more intriguing now. Personally I wouldn’t use it for connecting a mixer to my Bose systems, but that would be something to explore. I’m just looking to “cut the cord” so to speak for my 2 dynamic mics. 


Hi ST,

would like to share my experience with Xvive U3 wireless mic system i’ve been using for last few weeks now. I have connected 2 x U3  (for short) transmitters to the XLR L/R outputs of Bose T8S mixer (although one site need a very short extension due the physical dimensions of the units: without the extension, they simply won’t fit into the very tight space of the T8S inputs/outputs sit). The receivers are connected to the channel 1 on each of my Bose S1 PRO. 

System works flawlessly for us although distance between the T8S and either S1 PRO is usually no greater than 5-6 meters- that’s what we want: to hear ourselves via S1 PRO. But we have also tested that entire system for greater distance of approximately 12 meters on each site to see if there is any of dropout or degradation of sound. It does work very well, no problem. Batteries (recharcheable) would last approximately for up to 5 hours (U3) and S1 PRO batteries will work in similar fashion too. So they are totally wireless.

We havexexperience kind of statering noise and dropout once when microwave oven has been used innext room (not on the gig, just at home during the rehearsal. But that happened only once..

Great idea, great product, good quality, very quick paring system and overall we are happy to use it instead of the traditional cables (but we do carry these ones in the car, just in case). 

Also U3 do have that mic/line switch which in our way of using it is important, ‘cos mic position might and often run too hot on some occasions. Line position however is just perfect, no distortion or obvious degradation of sound quality. 




I've had great results with xVive U2 wireless systems on guitars and bass.

As long as I don't accidentally push the channel button when turning on the transmitter or receiver thus throwing them "out of sync"  :-)

Decent range, no apparent latency, long battery life and quick recharge.  It's nice to hear the microphone versions retain those qualities.

Too bad my microphones need phantom power.


Thanks @Chet and @Julian8023 for sharing your experiences with the Xvive U2 and U3 systems. I really love the idea to link a mixer output up to a S1 via the U3.

Julian: have you tried the U3 with a mic by chance and what did you think of it? Any tonal or noise issues? What mic did you use?

Chet: what guitars do you use the U2 on? I’ve seen warnings that they don’t work with active pickups so I’m concerned about using them with acoustic guitars that have active/preamped under saddle pickups. The company says the main issue with active pickups comes when there is an internal microphone involved in the pickup system. Without the internal mic they said it should work ok. 

I've used the U2s with active pickups in Fender 5 string bass, U-Bass, Godin fretless bass, Taylor T5z, Taylor K24CE and at both ends of my foot pedals including from a (2-channel mixer/)Tuner/Chorus/Digital Delay/Looper TO mixer.

I'm not sure what they mean by "internal microphone" issues.  Unless it's an internal mic that needs phantom power which the U2 system can't supply? 

My main working ax is a 2002 Taylor 514ce that has TWO pickup systems in it; the original Fishman Blender with a piezo pickup and microphone mixed together and a Fishman Rare Earth system with Omni Microphone in the sound hole and have used two of my U2 systems to send the signal to my pedals' mixer with no issues.

I'd say, they'll probably work 95%+ of the time.  It's been 100% for me.

Hi CityFolk,

re: the U3 wireless mic system you asked, we are using our Sennheiser mic for the vocalist, connected to her Boss VE-5 unit, which provides the phantom power too, so we never have tried the U3 for her mic at all - there is no need for it in our setup. Yet I have compare cheap Behringer mic connected via traditional mic lead with U3 (with the mic switch position of course) and found that the signal is somehow stronger, with no obvious tonal issue(s). 

I’ve told by sound specialist, that theoretically each venue could be a slightly different story when you’re using these wireless systems. And he mentioned the main “offender” creating any possible dropouts or distortion is how many people in the venue have their mobile with them and turn “on”. Last night we were working in “packed” with audience (100+) environment and I can only presume literally everybody have their own cellular these days, yet not a single issue we have experienced. All worked perefectly well.

Hope that short “report” might help some people to make their own decision whether they want to invest in U3 or similar product(s).
