Shure BLX Wireless System with E-Mic Fitness Headset Microphone – Exclusively from AV Now Fitness Sound

What is a wireless microphone system?

General Definition: A wireless microphone is a microphone without a physical cable connecting it directly to the amplifying equipment with which it is associated.

A wireless microphone system allows the user’s voice to be transmitted “wirelessly” to its receiver, located in the sound system.  The sound system amplifies the signal from the receiver and outputs it through the system’s speakers. 

A wireless mic system consists of three main components that operate together as low powered, individual radio station.


1.  Microphone: Though the first wireless mic systems were designed with handheld mics, nearly all fitness instructors prefer the hands-free freedom a headset mic allows.

Examples: Cyclemic Cycling headset microphone  E-mic Fitness Instructor Headset MicrophoneShure SM31FH Fitness headset microphone

The mic connects to the transmitter.


2. Transmitter: Wireless mic systems used for fitness originally all used body pack transmitters. The headset mic connects to a body pack transmitter via a short cable. In the early 2000s, Samson Technologies designed the first “transmitter on the headset” wireless mic, the Airline 77. Both types of transmitters – bodypack and transmitter-on-headset are widely used for group exercise instruction today and are available from many manufacturers.

  • The transmitter converts the audio from the microphone to radio waves and transmits them to the receiver.  

Examples: Shure BLX1 Bodypack TransmitterFitness Audio M-209c bodypack VHF transmitterSamson SWQTCE Airline 77 Headset and Transmitter


3. Receiver: Receives the radio transmission from the transmitter and converts it back to an audio signal so it can be amplified by the sound system. The receiver is typically located in the sound system or near enough to it to be connected by a short audio cable.

Examples: Audio-Technica UHF receiver Shure GLXD4 digital wireless microphone receiver Samson CR88 UHF wireless microphone receiver



Q: Is a wireless mic system all I need to for my class to hear me?

A: Wireless mic systems make no sound on their own. They must be connected to a sound system. Note: some ‘all-in-one’ portable sound systems have a wireless receiver built in, so this connection is already made. You need a compatible headset and transmitter and you are good to go do your class.

Q: Is a headset mic all I need for my class to hear me? 

A: Headset mics make no sound on their own. They are the first component in a wireless mic system. You need a complete wireless mic system connected to a sound system for your class to hear you.

Q: Will a Shure (for example) transmitter work with an Audio-Technica (for example) receiver?


  • Different brands of wireless are not compatible with each other due to the specific radio frequencies and methods of transmission each manufacturer uses. 
  • Generally speaking, a transmitter only works with the specific receiver it was designed to work with. Even if both pieces are from the same manufacturer, they need to be the same model and operate on the same frequency or frequency range. 
  • AV Now is always available to help you figure out whether wireless components are compatible or to let you know the components you need to make them work.

Q: Will an Audio-Technica (for example) headset mic work with a Shure (for example) body pack transmitter?

A. Headset mics don’t transmit anything and aren’t  frequency dependent.The bodypack and receiver are the “radio” components in the wireless system. The headset is simply the mic.  In theory, any headset mic should work with any bodypack transmitter.  However, each wireless manufacturer uses a different type of connector for their headsets and body packs. This makes them generally not interchangeable.  For example: Shure uses a 4-pin connector in configured in a 'Y' shape. Audio-Technica uses a 4-pin connector configured in a square shape. You can’t physically plug a Shure headset into an Audio-Technica body pack. 

A standard manufacturer’s headset can be re-terminated with a connector to match the transmitter you wish to plug into, but this is generally cost-prohibitive, sometimes technically-prohibitive. It’s usually best to simply get a headset that has the connector that matches what the transmitter is wired for. 

Fitness-Rated Replacement Headsets: AV Now Fitness Sound began as a company that specialized in providing replacement headsets designed to withstand the tough, sweaty group exercise environment.   This is still at the core of our business.  Literally tens of thousands of customers – including some of the largest fitness chains in the US – come to us for our Fitness Audio E-Mic or Fitness Audio Aeromic headset microphones.  These mics are designed specifically for fitness instructors. Most standard headset mics that come with a wireless mic system simply aren’t. 

E-Mics and Aeromics are offered with different connectors for all major transmitter bodypacks. If you switch wireless systems to a different manufacturer and connector type down the road, we can change the connector on your E-Mic or Aeromic so it will work with your new system. There’s a nominal service fee for a connector swap.  You still can’t plug in an E-Mic wired for Shure into an Audio-Technica transmitter, but we can swap the connector on your E-Mic so you can.

Important Wireless Mic Frequency Information:

According to FCC rules, wireless microphones capable of operating in the recently auctioned 600 MHz spectrum (616-653 MHz and 663-698 MHz) will eventually be prohibited by law after a transition period. Our best current information estimates the transition period will be approx. 3 years, or summer 2020.  This estimate may change over time.
The FCC’s official page regarding the 600MHz frequency auction and transition is Here

Customers using wireless systems that operate in the 600 MHz Band should plan to transition to another range of the wireless spectrum.
In the near term: If a local mobile broadband licensee begins using the 600 MHz Band during the transition period, the FCC mandates a 600MHz wireless mic user change frequencies to avoid interfering with them. In the longer term: it will eventually be illegal for manufacturers to sell or repair 600Mhz wireless mic equipment.

Wireless manufacturers have been in process of transitioning their gear to non-600MHz frequencies. Some – such as Shure- are beginning to offer rebates to help customers transition to new frequencies. We expect all manufacturers to offer rebates program as we move into the transition period.
AV Now Fitness Sound is here to help.

If you don’t know if your wireless mic system is in the 600MHz band, we’ll help you determine the frequency.

We will advise you of any rebates that may be applied to replacing 600mhz systems.

Please note:

• Headset mics that plug into a bodypack transmitter are not affected by FCC frequency regulations. They do not transmit a radio signal, the bodypack transmitter does.
• A bodypack transmitter may be affected.
• Cableless ‘transmitter-on-the-headset’ mics such as Samson Airline 77s, Fitness Audio Mini-TX's and Special Projects EVOs may be affected.
• If your mic system is frequency-selectable, it may be affected. The selectable frequencies may be in the 600MHz Band.

Please contact AV Now with any questions.

Welcome to another AV now tech corner. Today we're going to be going over putting together the equipment rack for one of our fitness studio sound systems. These systems are custom designed for the fitness industry and are incredibly simple to assemble and install.

A key feature of our sound systems is that you can easily put this gear together yourself. Our experts are here to support you the whole way by phone email and live chat on our website 

Let's get started.  Here's one of our carpeted rack cabinets. We've also got metal ones, plastic ones, some on wheels and some that mount to the wall. This model is just an example and it's what ships with many of our gym sound systems.

We recommend laying the rack on its back and setting the components on the rack rails. 

We recommend putting your power conditioner and mixer up top, but you can arrange it however you'd like. Once you've got them positioned the way you like, grab a screwdriver and put in the included screws (we recommend an electric model for speed). 

Now let's turn it around and look at the back. Here's where we're going to hook up the audio and power cables. 

Don't worry we always include a simple guide on what goes where whenever we ship a sound system. 

Firstwe'llhook up our music players to our mixer. Remember: outputs go into inputs. Now let's get our microphone system plugged into the mixer. 

This system has an amplifier, so we'll get that plugged in last.  Your system might have the amplifier built into the speakers, so this section might be a little different for you.  In that case, your mixer will connect directly to your speakers. 

Now we need to plug the power cords in for each component. 

The rack is all ready to go!

Sweat and electronics really don't mix, so things can get a little...funky. Cleaning the input connector on a wireless microphone bodypack transmitter is crucial in fitness facilities that use microphones for group exercise instruction. Here's a quick primer on how to do it and the tools needed.

It’s no big surprise that so many fitness centers and exercise classes start with using a less-than-ideal sound system.  After all, it’s supposed to be about fitness—not listening to music—right?  

In reality, a groupex fitness experience benefits from great sounding, motivational music. Group Ex instructors should be able to focus on their class, not dealing with an overly-complicated sound system or a system simply not designed to do what's needed in the grueling fitness environment.   
So a 'fitness sound system' has a rather hefty set of standards to meet in any kindofhighperformanceenvironment…much more than just playing some background tunes.
With this in mind,letslookat the 5 things that make a fitness sound system different from an ordinary PA system or a home stereo:
1.  Simplicity
While it might sound more complicated at first, the fact of the matter is that fitness sound systems are designed to provide exactly what an exercise class instructor needs.  

It starts with the brains of the system—a mixer with 2 wireless mic inputs and about 3 individual music channels to handle inputs from a CD player, portable music player, or other source device.  From there, it’s all about having the correct amplifier (whether built-in or external) and professional speakers that are perfectly sized for the environment.  

It’s really as simple as that; there’s no need for complex features like reverb that are found on PA systems designed for bands and other more complicated jobs.
2.  Group Ex Sound Clarity
A home theater system provides the ideal in-home movie watching experience; a dance club sound system is designed and tuned to provide club-shaking bass and volume.  But the demands placed on a fitness sound system go above and beyond—with group ex sound, it’s vital to have excellent performance both when it comes to playing great sounding music and having crystal-clear wireless mic clarity so the instructor can be heard by all.  

Quality fitness sound systems are custom designed to provide balance…the best of both worlds.
3.  Ease Of Use
A fitness instructor is usually much more interested in doing what it is they do best—instructing the fitness class—not running a 96-track sound system capable of running a world-class concert hall.  

Ideal fitness mixers will feature one easy to use master on/off switch, very simple sound adjustments and controls (without hundreds of knobs and sliders that nooneunderstands), and an allaroundself intuitive method of running the system.  In other words, it should just make sense to the person operating the sound system—no more, no less.
4.  Durability
Home stereo systems and most low-grade PA systems just aren’t up for the challenge that everyday use in a professional fitness environment requires. And of course, a high-performance fitness sound environment also presents its own unique set of challenges—things like extreme sweat and the potential for high impact that wireless microphones and other equipment must be specially designed to handle with ease.  

It’s also important to note that delicate home theater or stereo speakers are very easily damaged when used with wireless microphones that produce unpredictably high volume levels during regular use, especially with accidental feedback.  

Durability is an essential component in a quality fitness sound system.
5.  Support
It’s important to have a sound system that comes with complete technical support and advice, both before and after the purchase.  Because there is more to a pro-grade fitness sound system than using a boom box off the shelf, it’s always important to have someone who you can call and get quick, expert advice from people that actually know and understand your unique circumstances.  This is something only a fitness sound specialist can adequately provide on this level.
So while many fitness centers and exercise instructors begin by using a home stereo system or an ordinary everyday PA system, for most it doesn’t take long to realize the importance of graduating to a true fitness sound system that’s been professionally designed for the unique circumstances required. 
A genuine fitness sound system really does make all of the difference in the world—why not take your fitness center or exercise class to the next level soon?

Surround sound is great in a living room or a movie theater, but why do you want it in your group exercise studio?  We think you don't.

Our philosophy has always been that fitness instruction is a performance, and when you go see a performance, you'll usually notice that there aren't speakers behind you and they aren't in the corners of the room.  A group exercise sound system should provide forceful (some would say 'thumping') music with the voice just sitting on top.  If there are speakers in the back of the room competing with the ones at the front, speech intelligibility and the music's 'power' will usually be sacrificed.  Furthermore, surround sound only really works if there is program material that is supposed to surround the listener (think a car zooming by, or a spaceship, or any number of things that exist in movie sound, but never in a fitness class).

We get a lot of calls from fitness instructors and group exercise directors complaining about feedback on their wireless mic systems.  No problem, we love getting the calls, but we find that there is a lot of confusion about what feedback means in a sound system.
First of all, 'feedback' usually refers to the squealing or whale-like sound you get when a microphone picks itself up through the speakers, thus feeding the sound back into the speakers and making a loop.  Nobody likes to hear that right at the peak of an intense aerobics (or cycling (or any)) class.  There are a number of reasons that a microphone headset might feed back during use.  
The main remedies are to turn down the trim or gain control on your wireless microphone transmitter, rearrange the speakers in your group ex room so that they are not pointing back at the instructor (please don't put them in the four corners!), and adjust your equalizer controls to minimize the group of sounds (bass or treble) that is giving you issues.
Sound confusing?  It's really not that bad.  Give us a call at 800-491-6874 and we'll walk you through it step by step.  

P.S. if your wireless mic system is cutting in and out, making popping sounds, or you hear static, it's probably not 'feedback', but we can usually help with that, too.

Sometimes, the simple things make all the difference.  We've been selling sound gear exclusively to fitness facilities for a long time, and servicing equipment for almost as long.  We see a whole lot of sweat-damaged, nasty audio equipment, and we know that it doesn't always have to be that way.

A very simple and helpful solution to keep your wireless microphone equipment healthy is a mic belt.  (We also sometimes call them sports pouches; some people insist on calling them fanny packs...)  Well over 99% of wireless microphone systems that have a headset microphone still have belt-worn transmitter packs.  Those packs will get extremely sweaty during the course of a one-hour fitness class if they are clipped directly to the instructor's clothing.  Multiply that grime and moisture by several classes a day, and you've got a recipe for damaged electronics.

Simple fix: every instructor should wear their transmitter pack in a mic belt.  An investment of less than $40 can save a transmitter (some of which are nearly $300!).

Here at AV Now Fitness Sound, we get a lot of calls asking us for just speakers to hook up to an existing group exercise sound system.  Great!  We love outfitting your studios with the latest audio gear.  That said, we always like to try to make sure your stereo system is up to a certain standard of excellence.

For us, that means making sure that the amplifier in a fitness studio provides between 1.5 and 2 times the power rating listed on your speaker (in watts).  So, if you have a 100 Watt speaker, your amp should be between 150 and 200 Watts.  If you have two speakers, your amplifier should be able to provide 150 to 200 Watts per speaker.

A little known fun fact: more speakers blow from too little power than from too much.  

Questions?  Give us a call at 800-491-6874.  That's what we're here for!

AV Now Fitness Sound offers a variety of 'Fitness Rated' wireless headset mic systems specifically chosen to suit specific usage, brand preference and style choices. 

The general rule about the wireless systems we offer is: the more expensive systems perform better and are more durable-especially in group ex/fitness usage, where movement and sweat create a tough environment for any headset microphone system. 

In heavy use situations (multiple classes per day) medium to higher priced microphone systems will give you the best performance and be a better value in the long run. If you have budget constraints, rest assured that all mic systems offered by AV Now are professional quality and use an aerobics style headset designed for fitness use.

Note: these tips apply to the selection of wireless mic systems and replacement headset mics offered by AV Now Fitness Sound. 

Our 20 years experience providing thousands of wireless mic systems to the fitness industry -and the feedback from our customers about what works well -and what doesn't- means we only offer products that will withstand the demands put on them in the rugged, sweaty group ex fitness environment.

Prolong the life of your fitness headset mic and avoid "the crackles" by keeping both the headset connector plug and the body pack transmitter connector jack clean and protected. Sweat is a natural part of exercise and letting it remain in your connectors causes corrosion that will eventually to crackling, then connection failure. Proper storage of your headset mic and transmitter will also extend its “life before service is needed” timeframe. 

TIP 1: Clean and Protect 

Use 'DeOxit' cleaner and ‘eGloop' corrosion protector both connectors at least twice a month. Simply spray DeOxit into the connectors and gently tap out or swab out the debris it loosens. 

After the connectors are clean, dab a bit of eGloop marine-grade protectant gel into the connectors. eGloop will coat the prongs and holes, making both sides of the connection as sweat resistant as possible. 

Sweat kills mic connectors. DeOxit and eGloop protect. Both products available fromAV Now Fitness Sound

TIP 2: Let your headset mic dry out between uses

Whenever your microphone is not in use, store it someplace safe with plenty of air circulation – to promote drying. Having a hook near or inside your sound system rack makes hanging up to dry easy. 

If you’re an individual instructor and your headset mic travels with you, a great way to protect it and let it dry is storing it in a tupperware-type container with holes punched in the lid for ventilation. 

TIP 3: Don’t Do! 

One of the worst ways to store your headset mic is by wrapping/winding its cable around the bodypack transmitter and putting both pieces in an unventilated drawer. Not only does this not let the headset dry as effectively as hanging or storing in a ventilated space, you’ll decrease the life of your headset mic’s cable by winding it around the bodypack. Repeated wrapping/winding will put kinks in the cable which will eventually cause shorts in it. 

If you absolutely must use a drawer: gently loop the cable, making the loops as large as possible- and be careful not to close the drawer on the cable. We’ve repaired many headset cables that have been damaged by having a drawer closed on them. 

TIP 4: Back things up. 

Having a backup for critical equipment is one of the best ways to assure ‘the class will go on’ with little or no stress. We always recommend having a backup headset mic. A backup belt-pack transmitter is a good idea too, though most technical issues usually happen in the headset mic first. Even an inexpensive headset will do – as long as it has the proper connector type for your transmitter. 

A backup headset ensures you will have a working mic – and save your voice- while your main headset is repaired or replaced. 

Note: The above tips are for fitness headset mics which use a belt-pack transmitter. Some of these common sense type tips also apply to “cableless”/”transmitter-on-the-headset” mic systems too. Tips such as “let things dry between uses,” “handle with care when storing” and “always have a backup” are universal to all fitness mic systems.
