Reliability and Signal Strength

Reliability and signal strength is one of the most critical factors when determining a good wireless microphone system. I have witnessed too many shows ruined because the singer’s mic kept cutting out. After a few times, the singer will focus more on the fear of the mic cutting out again rather than the performance. It is vital to get a microphone with incredible frequency agility that’s able to dodge interference. Thus, to our next point.

The Reason Why The Shure QLXD24/B87A Has Incredible Signal Strength And Reliability

For one, its One-touch sync function feature automatically scans for the most robust open channels. This feature is an essential factor in reducing interference and dropouts.

Another incredible feature the QLXD24 has for a reliable RF connection is its digital predictive switching diversity. The 2 antennas work independently scanning for the clearest open channel. If one antenna receives interference, the other antenna unnoticeably picks up the transmission. The antennas consistently scan for the clearest open channel without pressing a button.

Shure QLXD24/B87A Durability + Longevity

Many wireless microphone systems that claim to be made of metal still however have parts made of plastic. Both the receiver and the Microphone for the Shure QLXD24/B87A are entirely made of metal with no plastic parts. This fact alone dramatically increases its durability and longevity that will protect your investment for years to come.

For touring bands or traveling, metal units are significantly more “roadworthy” than plastic units. Your music equipment is consistently being tossed around when you are touring from state to state. Whether it is from the van/bus, back into the van/bus, or the singer who dances across stage with the mic. Overall, the Shure QLXD24/B87A made of only metal is a huge plus.

Sound Quality (Beta 87A Microphone)

Out of every single wireless microphone I have experienced firsthand, the Beta 87A sound quality is second to none. There are a few reasons why this wireless microphone produces such an incredibly rich, detailed, and bright vocal response.

The B87A that comes with this system is a supercardioid condenser microphone. In general, condenser microphones are typically used in the studio that is much more articulate and detailed. They tend to pick up all the nuances of your voice with the downside of picking up sound elsewhere. Contrary to that belief, I and most users of this mic claim there are no issues with picking up unwanted noise with the B87A mic while maintaining the positive benefits of a condenser. One reason may be the microphone polar pattern being a supercardioid that helps reject unwanted background noise.

The fact that the Beta 87A is a rare condenser microphone optimized for live performance alone is a giant reason the sound quality is of the highest grade by Shure. However, that is not the only reason that gives the Shure QLXD24/B87A such fantastic sound quality.

The system provides a 24-bit/48K sampling rate for the purest digital transmission. With a frequency response of 20Hz-20kHz while the mic gives you 50Hz-20kHz allows all the frequencies of the vocal spectrum to be heard. The very low latency is unnoticeable at 2.9ms while reaping the positive benefits of a digital rather than an analog system. Last but not least, the Shure QLXD24/B87A gives you above 120dB of dynamic range.

QLXD24 Receiver

Wireless Systems For Bass

The Shure QLXD 4 receiver is made of all metal with two fold-able antenna’s. The picture, however, makes it seem bigger than it actually is. It’s conveniently small, making it easy to travel with.

Many systems have poor lighting on the front screen that can make it hard to see the menu. This can become a very stressful situation for certain last-minute adjustments on a lit stage or outside. Luckily, the QLXD 4’s receiver provides a very bright screen with LCD lights to easily navigate through the menus regardless of the scenery.


The Shure QLXD 24 is an overall very convenient wireless microphone system for a number of reasons.
  1. The receiver is rack-mountable, which in it itself is a massive benefit for those with a rackmount.
  2. An easy setup, its One-touch sync function feature automatically scans for the most robust open channels
  3. The microphone gives you the option to either use 2 AA batteries, or Shures state-of-the-art rechargeable lithium-ion battery that provides 10 hours of playtime per charge. The Shure’s lithium-ion battery saves you money from cutting out consistent battery purchases. It also saves a great deal of hassle that comes with disposable batteries.

Shure QLXD24/B87A Range

The Shure QLXD 24/B87A provides a vast amount of range for a digital wireless microphone of 300 feet. Imagine crowd surfing a football field of your fans. Three hundred feet gives you more than enough room to cover any event, concert, stage, house of worship, etc.! With the QLXD 24, range will never be an issue.

The Benefits Of The QLXD24/B87A Being Digital Rather Than Analog

In Short, digital wireless microphone systems have arguably better audio clarity. Analog systems must struggle to keep the dynamic range within a legal bandwidth of 200 kilohertz by using companders and pre-emphasis that have their limits in high frequencies. These audio limits are erased with a digital wireless system, thus, much better sound quality.

Digital Wireless Mic Benefits

  • Batteries last 30-40% longer.
  • Digital systems can give a flat frequency across the entire audio range. The sound of the capsule will not be affected where analog has a higher chance that it would be.
  • Has less of a chance the radio link or Rf noise will affect the signal.
  • Depending on the manufacturer and model, digital systems can often deliver nearly twice the channels in the same slice of the spectrum as their analog counterparts.
  • Digital systems can produce roughly twice the channels in the same spectrum. This is not the case for all systems; it depends on the manufacturer make and model. Unfortunately, to get the clear and crisp audio of digital wireless under challenging circumstances, the wireless systems are typically on the more expensive side.
  • Signal encryption is perfect for information-sensitive events.

Why Use Wireless Over A Wired Microphone?

Best Wireless Microphone System

There are many benefits of using a wireless microphone over a wired one. First of all, aesthetic. For bands and DJ’s that play weddings, wireless is an absolute must. It’s abnormally tacky to pass off a wired microphone to the newlyweds’ family member for his or her speech. DJ’s and MC’s that perform high-energy shows outside weddings need the wireless freedom to move around and excite the crowd. 

Being attached to an electric leash will significantly hurt your performance and put a damper on delivering your best live show. Going wireless allows you to reach your maximum stage presence potential instead of worrying about tripping on, stepping on, or pulling out your mic cable, using a wireless enables you the freedom to reach your maximum potential. 

Wireless microphones also decrease the cable spaghetti on the stage floor. A stage filled with cables all over the floor looks tacky and unprofessional. A clean stage boosts the overall visual performance of the show and makes for a safer performance area.

The Shure QLXD24/B87A is the all-around best wireless microphone system without spending 5000 dollars. It checks all the boxes at a competitive price. We highly recommend this wireless microphone system for just about any application.
