BLX24R/B58
Wireless Vocal Rack-mount System with Beta 58A
The Beta 58A dynamic vocal microphone is precision-engineered for live performance and project studio recording. A tailored frequency response accentuates vocals, and the supercardioid pattern isolates from other sound sources. It combines simple setup and an intuitive interface in a rack-mount receiver.
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.
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.
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.
- The PGA31 is a comfortable, durable headset microphone for active performance.
- Instrumentalists can attach the WB98H/C flexible gooseneck instrument microphone for brass, woodwind, and percussion applications.
- The WA302 guitar cable lets you connect to a guitar or bass.
