Shure BLX24R/B58 Rackmount Wireless Handheld Microphone System with Beta 58A Capsule (H9: 512 to 542 MHz)

The Shure BLX24R/B58 brings performers and presenters a cost-effective wireless handheld microphone system with quality sound, simple setup, intuitive operation, and dependable performance right out of the box. It includes the rugged BLX4R single-channel receiver with LCD display, adjustable output level, and removable antennas for rackmounting the unit—ideal for sound-reinforcement applications in small venues, wedding halls, and houses of worship.

The BLX24R/B58 also includes a handheld transmitter equipped with an integrated Beta 58A dynamic supercardioid microphone capsule optimized for crisp, present vocals with a brightened midrange and bass roll-off to control the proximity effect. The receiver features one-touch QuickScan frequency selection to quickly search 123 available frequencies and locate a clean RF channel in case of interference. The system provides up to 14 hours of continuous use with two AA batteries, at a range up to 300'. Up to 12 mic channels can operate simultaneously in each frequency band.

Beta 58A Mic Capsule Tailored for Clear Vocals and Speech

The Beta 58A dynamic capsule features a neodymium magnet for greater sensitivity and higher output, as well as a tight supercardioid polar pattern that greatly minimizes background noise and feedback. The dent-resistant steel mesh grille resists wear and abuse. The built-in pop filter reduces undesirable wind and breath noise for clear and intelligible speech.

Lightweight Handheld Transmitter

The durable BLX2 handheld transmitter offers a lightweight, ergonomic design and is comfortable to hold. Group and channel selection buttons allow for quick and simple frequency matching with the receiver. Other features include an easily accessible on/off button, adjustable gain control, and a black identification cap. The WA621 Color ID Caps kit containing assorted colored caps is available as an optional accessory.

Easy-to-Use Rackmount Receiver for Quality Audio

The BLX4R receiver employs a microprocessor-controlled antenna diversity system to improve the quality and reliability of your wireless audio. The receiver can be rackmounted with the included hardware, allowing you to position the two removable antennas on the front of the rack for optimal signal reception.

The LCD display shows group and channel settings, and allows you to meter audio level and signal strength. An LED indicator even lets you keep an eye on the transmitter's remaining battery life. The unit offers 1/4" and XLR connectors with adjustable output level for flexible connectivity to PA systems and mixing boards.

A Versatile System to Meet Your Needs

Shure offers the BLX2 handheld transmitter with a variety of mic capsules to choose from.

The BLX1 bodypack transmitter accommodates a wide range of hands-free microphone options including lavalier, headset, instrument, and earset models to adapt your BLX system as your needs evolve:

  • The WL185 lavalier mic and discrete MX153 sub-miniature earset mic provide exceptional clarity in spoken word applications.
