[BNC, 1 V] Bought this wireless lavalier microphone system for a presentation. It worked exactly as advertised. The sound was clean, clear, and had plenty of volume to spare. As was noted in other reviews, the tie clip comes loose fairly easily, but a small piece of scotch tape worked great. It was a breeze to setup, and extremely simple to use. Our school will be using it for a while.

[50 ohms] I’ve been a staunch supporter of the sm series for years, and this is a great upgrade from the classic small body unit. The menu functionality is easy and faster than the old one, and the recorder function is awesome for super long or wide shots. Battery life is comparable to the old sm. Can’t wait to add more to my kit!

[BNC, 1 V] The PSC RF Multi SMA worked great. My range seemed to increase and the signal strength remained stable.

[12.6 - 15 V] Worth the money. Reliable for studio use in educational video production.

I keep it on a sennheiser mkh 416. Clean. I scan for a new frequency every session. I tend to keep it plugged in via USB For continuous power, running it into a Sony mi interface, directly into a Sony a7s3.

Great on handheld and other mics.

Its decent for Shute sm7b, which is power hungry, but gets the job done nicely.

416 is my favorite mic for this.

Studio is by major Burbank movie studios, city power grid, and airport but no problems in 6 months of heavy, daily use.

[50 ohms] These work just fine. Have used them in Manhattan for PA use in panel discussions and the like with no problems. This is notable because of all the RF in the air here. I now have 5 of these units, including 4 lavaliers and 1 handheld. They have all worked fine right out of the box. I have not used them at their full maximum spec. range of 300ft, but 75ft has been no problem, even through one wall. Some have commented that their construction seems flimsy, but in my experience they are built well enough, especially considering their performance at a fraction of the price of other brands. And I have seen several wedding bands that use them exclusively. The fact that these are frequency agile is a big plus, as you can mix mikes and base units within their band (units are fixed to either C or D band in the US), and choose from 16 channels per band. Biggest complaint, by far, is that the foam windscreen is easy to lose, so maybe get some extras - they can be found cheaply enough - or find a way to fix the windscreen to the mike. BTW the replacement plug-in mikes are quite inexpensive, and I've used these quite successfully to replace mikes on Shure SLX body packs.

[N type] The challenge was that for zoom tap dance, fitness and jazz classes, there is vocal instruction and music, add to this sounds from tap shoes, w/all happening at the same time. To see the instructor's whole body he/she is usually far from the computer microphone (which is usually minimal at best). Paired with a zoom U-22, this system made a big difference. It works perfectly.
B&H is the best. Good advice, product options and fast delivery.

[470 - 860 MHz] so portable but the power switch stick is so fragile I have to say this is a bad design for location recording...

[N type] I bought 5 pieces of LMB-B1 and I am Happy with themclean audio As all Lectrosonics,Easy to useBatteries last for a long time. it is not good distance and Audio quality when used with UCR 201. i test them out it is better to used them with LR - 411- Srb or Venue with VRT, i use them with 401 it is good but not good distance. You should pay attention to the door of the batteries a little bit sensitive.

[4.5 MHz] I purchased a Sony kit with a dual-channel receiver and two belt packs. To this I added a wireless handheld microphone and most recently the UTX-P40 Plug-on transmitter. This system has worked flawlessly, even in noisy environments like downtown Chicago. Configuration of the components is confusing, but nearly identical in each device. If you have NFC, configuration of the transmitters is automated. Unfortunately my receiver does not have NFC.

[8 A] If you can handle it’s larger size, the Lmb is the best 50mw transmitter in the market. Greatly exceeds similar priced sennheiser 500 series transmitters in range.
