Shure BLX24R/SM58: The SM58, Rack-Ready

The SM58’s warm, clear vocal sound and cardioid feedback rejection meet a rack-mount receiver built for professional installs. Mount the BLX4R in your rack, relocate the antennas to the front for better reception, and keep your system tidy and secure.

Clear Status at a Glance

The receiver’s LCD displays group and channel and meters audio level and RF strength, while a battery indicator shows the transmitter’s remaining life, so you can head off problems before they reach the audience.

Setting Up the BLX24R/SM58

Mount the BLX4R in your rack with the included hardware and front-mount the antennas. Power on and run QuickScan, then set the BLX2 handheld to the matching group and channel. Connect the receiver’s XLR or 1/4-inch output to your mixer and adjust the output level to match.

What to Pair With the BLX24R/SM58

Pair the BLX24R/SM58 with a rack case, rechargeable AA batteries, a rack power conditioner such as the Radial Power-1, an XLR cable, and the WA621 color ID caps for multi-mic racks.

Expandable System

Run up to 12 compatible BLX systems per frequency band, and add BLX1 bodypack systems with lavalier, headset, earset, or instrument mics as your needs grow.

Built for Installs and Rentals

Rack mounting, front antennas, and clear metering make the BLX24R/SM58 a dependable choice for church racks, school auditoriums, conference centers, and rental inventory.

Tips for Reliable Wireless

Keep antennas in line of sight with the stage, away from metal and Wi-Fi equipment, and rescan at each new venue. Start each event with fresh or fully charged batteries.

Microphone Technique

Hold the SM58 one to two inches from the mouth and keep it pointed at your mouth to take advantage of the cardioid pattern. Avoid cupping the grille, which invites feedback and muddies the tone.

BLX24R vs. BLX24

Both use the same SM58 handheld and BLX wireless technology. The BLX24R adds a rack-mount receiver with front-mountable antennas, LCD metering, and a battery indicator, while the BLX24 uses a compact tabletop receiver.
