I'm doing a spin studio. They are having wireless interference issues. My gf seeing and hearing all the calls and stress this cause ,called her friend who was upper management at a large gym chain. Said they had tons of problems with wireless mics.

But the owner is saying the other studios in the area. Use wireless mics without any problems?

Having been to hundreds of spin classes in said large gym chains the biggest problem I see is the headset mics have the shit beaten out of them and the bodypacks come in second. Never wireless interference.

The Gold's Gym I went to for years used Shure and while the batteries died pretty quickly I never heard any wireless problems.

I did a fitness place last year and the owner has a cheapo wireless from Radio Shack, which she said had problems at the old location, but it has worked perfectly at the new one, even though the receiver is on the other side of a block wall. It's probably mounted higher than before, so that probably helps.

She thought the old transmitter died because of sweat but I have seen the transmitters fail because people like to smack it in their palm when they remove the batteries.

It could be the frequency of operation. If these mics are old, get tge frequency rabge off the FCC label and verify that these are still good frequencies.

On the ither hand, we have four UHF mics and there are TV channels near tgeir frequencies but we have zero interference.

By the way, I smack remotes to remove batteries but it's just stooopid to EVER smack a microphone. And anyone who drops a microphone has bought it at full price!

too many questions to answer that haven't been asked. You may want to consult with a supplier who has worked with microphones and commercial systems. I know one...

I have a client with two Spin studios, they were using Samsun Wireless Airline 88s for years.

I just looked over my order history and realize I have been replacing the mics every two months. Now that the FCC has changed the spectrum Samsun has revamped the mics and they are horrible!!

The mics now have a magnetic charger port that breaks away like a Mac book, the neck looks like the arm on Dr Octo from Spider Man.

The instructors prefer this to body packs as the transmitter is built into the head band.

I looked around and no one is making anything like them... except for 3M for McDonalds. I asked her if she would try them and she said they don't work in a drive-through.

Last show I mixed with musician supplied Samson wireless had the feature where when the transmitter connected to the receiver in the middle of the show it made zapping sounds. It only did it once every thirty seconds, of course. The performer was about thirty feet from the receiver.

Agreed, the older Samsun mics were problematic, but the newer gear seems to work better but the design features are too flaky.

I installed 2 samson Airline 88 in a gym in NYC but I had the move the receiver into the same room as the headset. The sound quality was not clear no matter what channel I used when I put it in the rack which is in the floor below. Luckily we ran cables just in case.

They also tried shure units before the samson with the bodypack which did work in the rack but the instructors didnt like the bodypacks with pilates and other dance classes. The bodypacks might work with a spin class though. The shure also has a scan feature which the samson does not have.

Line of sight the samson should work. I am not sure about durability though but it would be smart if you get the insurance from amazon.

Shure GLX system has a rechargeable battery.

Another set that works good with no bodypack is the EVO but its very expensive and the durability might not be great.

You could run coax and extend the receiver or purchase an antenna extension.


Do you know which model the EV is?

At the risk of being rude, be careful about running coax to extend antennas. Good luck with your project.

This kit from Shure - UA874 is run over coax??

Yes, but not rg6 or rg6quad.

Many kinds of "coax" out there. No mention of RG-6 was made. So, what's the preferred type? I've used 50 ohm rg-58 coax many a time to extend antenna for wifi, zigbee, and other RF w/o issues.

Sorry- used the rg-n? That came with it.
