Question about Shure SLX UHF Headset Wireless System Microphone

1 Answer

Shure SLX Wireless Microphone Packs

We employ five of the Shure packs for professional use during a theatrical show. They are kept on the performer's bodies using proper porous mike 'bum packs'. Though generally reliable, we do have ongoing problems with mystery cut outs (after initial mike checks are done) and what I believe are issues with sweat condensation, interference from other electrical equipment (lights, cabling etc) and possible loss of integrity due to placement of receiver units.
1. What is the best way to keep the packs (and receivers) clean, water and sweat free and maintain the integrity of their electronics? Any special products, tools or equipment for this?
2. What is the optimum placement of receiver units for the mikes that will minimise or eradicate drop out? How should they be positioned? can they be stacked on top of eachother?
3. What equipment, lighting, cabling will interfere with the signal and how can we minimise this disruption?
4. Where on the body is the best place to position these mike packs? (to avoid excessive heat, sweat, damage etc)
5. Is it advisable to reinforce the connection between the headpiece wire and it's plug with a rolled piece of thin cardboard to prevent wire stress?
6. What is the best way to 'toughen' the headpiece wire for rough and tumble stage use?
Please email for responses.
Thank you.

I'm glad you brought this up. I had the same issues with sweat with someone wearing this. The best thing to do about this is to air dry them. If you use any chemicals such as a sanitizer, only use it on the plastic piece the goes around the head. Make sure it is safe to use on plastic surfaces. The electronics are protected very well on the headsets to prevent them from getting moisture inside but inspect the units for any cracks. If the mic was dropping it would be caused by a short in the wire between the headset and the pack.

The units are designed to be stacked on top of each other, but if the range from the mixer unit to the stage is too far, there are extension antennas you can get to amplify the signal on the receiver end. Having the transmitter and receiver too far apart or obstructed due to walls, can cause the signal to drop.

What is the range between the mixer board and the stage? Is the mixer board located in on another floor with a wall in front of it?

reinforcing the microphones may make it tough for the next person to use them if they need to be adjusted. It could void the warranty if it is still under coverage.

My right ear bud cuts out every time I move my head. I've only had this pair about six months.

It shows that there is a loose connection.

Take the item back to place of purchase and get a replacement. It should be under warranty.

Take care!

Loss of signal

The receptor in the Logitech MP3 Wireless and Ipod wireless headphones is located in the right speaker of the headphones, so place your player in a pocket in the right side of your coat.
