Wireless Microphone System

The Shure GLXD24R/B87A with the Beta 87A is an incredible digital wireless solution for the price. This system checks 4 out of 5 boxes for what to look for in a wireless mic.

Reliability/Signal Strength

With a globally unlicensed 2.4GHz frequency band, the Shure GLXD24R has a much higher chance of a secure future from the FCC auctioning off frequencies. This system features Shure’s state-of-the-art automatic frequency management and bidirectional communication that lets your transmitter automatically link to your receiver and follow any frequency changes.

Each channel uses 6 different frequencies that continuously scan to monitor the frequency condition. After it finds the 3 clearest channels, it transmits the audio signal upon the 3 clearest audio frequencies of the 6 available. If one of the frequencies gets interference or conditions deteriorate, it automatically changes to a backup frequency without interrupting the audio. This reason is why GLXD systems have been raved about for signal strength and clarity for years.


The Shure GLXD family has the longest battery life of any wireless microphone system of 16 hours. Better yet, it uses lithium-ion rechargeable batteries that are conveniently charged by plugging the battery into the receiver’s docking port. Not needing disposable batteries ends up saving money and becomes much less of a hassle.

Hypothetically in a situation where your GLXD 16 is completely dead and you’re already at the gig, only 15 minutes of charge gives you 90 minutes of playtime. This definitely comes in handy for a bad situation.

Microphone and Sound Quality

Like mentioned earlier, the Beta 87A is an outstanding supercardioid condenser microphone with excellent sound quality. Condenser microphones are much more detailed and articulate that pick up all the nuances of your voice. The mic is either charged by 2 AA batteries or Shure’s Rechargeable Lithium-ion battery but it’s best to use the Lithium-ion battery that it comes with.


The Shure GLXD24R is a rack-mountable metal receiver able to take on extreme touring conditions for years to come.


The one thing that the Shure GLXD24R lacks is its range of Indoors: Up to 100 ft. Line-of-sight (200 ft. max); Outdoors: Up to 65 ft. Line-of-sight (165 ft. ideal conditions). Most systems on this list have 300+ feet of range. For singers or speakers who don’t need above 200 feet radius of range, this system is a sound choice.
