Shure BLX24R / SM58 Wireless System (Rack) M17

Legendary SM58 Sound with Professional Wireless Performance

The Shure BLX24R/SM58 Rackmount Wireless System, operating on the M17 frequency band (662–686 MHz, subject to Australian regulations), combines the iconic SM58® dynamic vocal microphone capsule with a rack-mountable BLX4R receiver for professional-quality audio and robust wireless performance. Designed for vocalists, presenters, and performers across Australia, this system offers simple setup and reliable operation, making it ideal for live performances, events, schools, and houses of worship.

Crystal-Clear Vocal Reproduction

The SM58 capsule is the industry standard for live vocals, featuring a cardioid polar pattern that minimizes background noise and feedback for focused audio capture. Its tailored frequency response (50 Hz – 15 kHz) with a brightened midrange and bass roll-off delivers warm, clear vocals that cut through the mix. The BLX24R system provides reliable analog wireless transmission with a 100 m (300 ft) line-of-sight range, allowing performers to move freely without sacrificing sound quality. The integrated pop filter reduces plosives for clean, intelligible speech.

Professional Setup and Durable Design

The BLX4R rack-mount receiver features microprocessor-controlled internal antenna diversity and one-touch QuickScan frequency selection to quickly locate the best open frequency, minimizing interference. With removable antennas and included rack-mount hardware, it’s ideal for permanent installations in small venues or portable setups. The receiver’s LCD display shows group and channel settings, audio levels, and signal strength, while adjustable XLR and 1/4″ outputs ensure flexible connectivity. The BLX2/SM58 transmitter, built with lightweight, rugged construction, offers up to 14 hours of battery life with two AA batteries (included) and includes a two-color LED for power and battery status. The system supports up to 12 compatible channels per frequency band.
