The BLX24R features a rugged half-rack receiver with removable antennas, one-touch QuickScan frequency selection for effortless setup, and an impressive 300-foot operating range that lets your team move freely throughout your sanctuary. With up to 14 hours of continuous use on just two AA batteries and rack-mount hardware included, the BLX24R is designed for churches and venues that want the reliability of Shure wireless performance in a clean, professional installation.

Professional Rack-Mount Wireless for Permanent Installations

When your church or venue has invested in a proper equipment rack, the Shure BLX24R wireless system gives you all the benefits of wireless freedom with the clean, organized look of a professional installation. The BLX4R receiver is a half-rack unit that mounts securely in your sound booth or tech area, keeping your wireless receivers organized and accessible while freeing up table space. The removable antennas can be positioned on the front of your rack for optimal signal reception, ensuring reliable performance throughout your worship space.

Why Churches Choose the BLX24R Rack-Mount System

Church sound teams consistently praise the BLX24R for its reliability during services and ease of use for volunteers. The rack-mount design means your receivers stay in one place—no more hunting for the tabletop receiver that someone moved or worrying about accidentally unplugging it during setup. Everything stays connected and ready to go week after week. The system’s one-touch QuickScan feature automatically finds the clearest available frequency, which means even your newest volunteers can get wireless microphones working quickly without technical training.

Customers report excellent sound quality that rivals their wired microphones, with many churches using these systems for years without any issues. The 300-foot operating range means pastors can walk throughout the sanctuary during their message, worship leaders can move across the entire platform, and guest speakers can present from anywhere without signal dropouts. Church audio volunteers especially appreciate that the rack-mount receiver has an LCD display showing detailed RF and audio metering, making it easy to monitor signal strength and adjust levels as needed.

Built for the Demands of Weekly Services

The BLX24R system handles the real-world challenges that churches face every Sunday. Whether you’re dealing with multiple wireless systems running simultaneously, varying skill levels among your sound team volunteers, or the need for microphones that can handle everything from quiet spoken prayers to energetic worship music, this system delivers consistent, professional performance. The 14-hour battery life means you can use these microphones for multiple services, rehearsals, and special events without constantly swapping batteries—many churches report changing batteries only once a month even with regular use.

Both the SM58 and Beta58A microphone capsules are legendary for their durability. They can handle being passed between multiple speakers during testimony time, used by children during Christmas programs, or dropped during setup without missing a beat. The microphones feature advanced shock mount systems that minimize handling noise, so you won’t hear loud thumps through your sound system when someone adjusts their grip or accidentally bumps the mic.

Expandable System That Grows With Your Ministry

Because you can run up to 12 BLX systems simultaneously in the same frequency band, you can start with one or two wireless microphones and expand as your worship team grows. Add wireless microphones for additional vocalists, a bodypack system for your worship pastor’s headset microphone, or lavalier systems for guest speakers—all working together without interference. The rack-mount design makes it easy to keep adding receivers to your equipment rack as your needs expand, maintaining a clean, professional look in your sound booth.

SM58 Or B58 Capsule

The Shure BLX24R system is available with two different professional microphone capsules, each with distinct characteristics that make them ideal for different applications and voices. Both capsules deliver exceptional Shure sound quality and legendary durability—the choice between them comes down to your specific needs and vocal characteristics.

Feature SM58 (BLX24R/SM58) Beta58A (BLX24R/B58)
Polar Pattern Cardioid Supercardioid
Frequency Response 50 Hz – 15 kHz 50 Hz – 16 kHz
Output Level Standard output 4 dB hotter output
Tonal Character Warm, smooth midrange Brighter, more detailed highs
Feedback Rejection Excellent (rejects from rear) Superior (rejects from sides)
Best For General worship vocals, speaking, louder singers Lead vocals, quieter singers, high-feedback environments
Grille Steel mesh Hardened steel (more dent-resistant)

Which Capsule Should You Choose?

  • Choose the SM58 if: You need an all-around workhorse microphone that handles both speaking and singing well. It’s perfect for churches where the same mic gets used by multiple people—pastors, worship leaders, and guest speakers. The SM58’s warm, familiar sound works beautifully for most voices and its cardioid pattern is forgiving if people don’t have perfect mic technique. This is the industry-standard choice that’s been trusted on stages worldwide for decades.
  • Choose the Beta58A if: You have lead vocalists who need extra presence and clarity in the mix, singers with softer voices who need more output, or you’re dealing with a challenging acoustic environment with lots of stage volume. The Beta58A’s supercardioid pattern makes it significantly more resistant to feedback, which is especially valuable if your worship leader needs to stand close to floor monitors. The brighter, more detailed sound helps vocals cut through a full band mix. It’s Shure’s premium upgrade for churches that want the absolute best vocal clarity.

Frequency Band Selection

Wireless microphone systems operate on specific radio frequencies, and different frequency bands are available for different regions. Before purchasing, you’ll need to select the appropriate frequency band for your location. The BLX24R system is available in multiple frequency bands:

Band Frequency Range Common Regions
H9 512-542 MHz USA, Americas
H10 542-572 MHz USA, Americas
H11 572-596 MHz USA, Americas
J11 596-616 MHz USA, Americas

Important: Use Shure’s Wireless Frequency Finder tool on their website to determine which frequency band is legal and will work best in your specific location. Frequency regulations vary by region, and some frequencies may be occupied by TV stations or other licensed users in your area. If you have overlapping frequency bands (like H9 and H10), they can often work together as long as you properly coordinate frequencies using the QuickScan feature.

FAQ

  • What’s the difference between the SM58 and Beta58A capsules? The SM58 has a cardioid polar pattern with warm, smooth sound—perfect for general worship and speaking applications. The Beta58A has a supercardioid pattern with brighter, more detailed highs and 4 dB more output—ideal for lead vocals and high-feedback environments. The Beta58A also has a hardened steel grille that’s more resistant to dents. Both are exceptional microphones; the choice depends on your specific needs and vocal characteristics.
  • Can I swap between SM58 and Beta58A capsules later? The microphone capsule is integrated into the handheld transmitter, so you can’t swap capsules on a single transmitter. However, you can purchase additional handheld transmitters with different capsules (BLX2/SM58 or BLX2/B58) and use them with the same receiver, giving you flexibility to choose the right mic for each application.
  • How many BLX24R systems can I use at the same time in my church? You can operate up to 12 systems simultaneously in each frequency band, depending on your RF environment and proper frequency coordination. For most churches, this means you can have multiple vocalists, speakers, and instruments all on wireless without interference.
  • How do I know which frequency band to choose? Before purchasing, visit Shure’s Wireless Frequency Finder tool on their website and enter your zip code. It will show you which frequency bands are legal and recommended for your area. Different frequency bands are affected by local TV stations and other licensed users, so it’s important to choose the right band for your location.
  • Can I use different frequency bands together (like H9 and H10)? Yes! If the frequency bands overlap (like H9: 512-542 MHz and H10: 542-572 MHz), they can work together. Use the QuickScan feature on each receiver to find clear frequencies, and the systems will automatically avoid interference with each other.
  • Do both capsule options have the same range and battery life? Yes. Both the SM58 and Beta58A versions have the same 300-foot operating range and up to 14 hours of battery life. The only differences are in the microphone capsule characteristics—polar pattern, frequency response, and tonal quality.
  • Will this work in my existing equipment rack? Yes. The BLX4R is a half-rack receiver (takes up half the width of a standard 19-inch rack space) and comes with all the hardware needed for rack mounting. You can mount two half-rack receivers side-by-side in a single rack space, making efficient use of your rack real estate.
  • Can I add bodypack transmitters for headset or lavalier microphones? Absolutely. You can purchase Shure BLX1 bodypack transmitters separately and pair them with the same BLX4R receiver. This allows you to use lavalier microphones, headset microphones, or instrument cables with your existing system.
  • How does the removable antenna feature work? The BLX4R comes with two removable 1/4-wave antennas. When you rack-mount the receiver, you can position these antennas on the front of the rack for optimal signal reception. This is better than having the antennas stuck on the back of your equipment rack where they might be blocked.
  • Is the BLX24R better than the tabletop BLX24 system? They’re the same system with different receiver form factors. The BLX24R has a rack-mountable receiver (BLX4R) with removable antennas and an LCD display, while the BLX24 has a compact tabletop receiver (BLX4) with internal antennas. Choose the rack-mount version if you have an equipment rack and want a permanent, professional installation. Choose the tabletop version if you need portability or don’t have rack space.
  • Do I need a license to operate this wireless system? Most users in the United States do not need a license to operate BLX systems. However, you must operate within the legal frequency ranges for your location and at the system’s low power level. The system is designed for unlicensed operation in most areas.
  • What happens when the batteries start to run low? The LED indicator on the transmitter turns red when approximately 60 minutes of battery life remain, giving you plenty of warning to change batteries before they die during a service. The receiver’s LCD display also shows battery status for easy monitoring from your sound booth.
