Home on the Range...Of Wireless Transmission

One of the most important features in Revolabs’ products is the ability to change the transmission distance of the receivers.  Whenever deploying a system, we always suggest that you not leave it on the highest setting possible, but rather configure it to whatever distance setting is “just a bit bigger than the room.”  Why you ask?  Well, there are a few reasons…

Have you ever had that nightmare where you forget you have one of our wearable microphones on and leave a meeting?  Maybe you head to the elevator and discuss something private or worse… head straight to the bathroom.  Well, thankfully the engineers at Revolabs have had that nightmare too, and done something in our products to prevent it from becoming your reality.  When a mic gets outside of the transmission range of the receiver base, it will cut the audio, then start a flash sequence on the mic’s LED that is green-amber-red.   Most importantly, it will also then start beeping every few seconds to remind you that you forgot to take off the microphone.  So when installing a system, think about when you want this sequence of events to start happening, and then set the receiver’s transmission power to the distance that matches your needs.  When you do get out of range, simply head back to the conference room and put the mic back in the charger.  Once back inside transmission range, the mic will automatically pair back up (muted) with the channel it was on, so there is no need to re-pair it.

Another important reason why transmission ranges need to be set appropriately is to mitigate the number of 3rd party devices in the area that may interfere with our microphones.   By creating a smaller RF footprint with your Revolabs receiver, you minimize the area in which the receivers are unnecessarily covering.  This smaller footprint means fewer overlay with other devices that may also transmitting in the same frequency range.  It’s easy to think that by increasing the transmission power you can somehow bully other devices in the RF space, but that increase in fact can actually cause more problems because you’ve increased the area in which you’re trying to share a finite number of channels in the RF space.

When doing an installation, the best practice is to start a receiver off at the lowest setting.  If it covers the room and all mics stay linked, great!  If not, then bump it up to the next power level setting and continue to do so until the entire room is “covered”, meaning the microphones don’t drop out at all in any part of the room.  Then, walk out of the conference room , and see if you get the mic to respond properly when out of range, at a reasonable distance from the room.
