Shure BLX24R/B58-J11 Half Rack Wireless System with BETA58A Handheld Vocal MicrophoneSince 1932, the name "Shure" has been synonymous with uncompromising excellence in audio in general, and microphones in particular. The BLX Series Wireless Systems continue this tradition of perfection by offering the performer wireless solutions to meet every need, with the sound that's made Shure the go-to company when quality and reliability are absolutely critical.
The BLX24R/B58 system includes the BLX4R diversity half rack receiver, and one BLX2 handheld transmitter with the Beta 58A vocal microphone cartridge.
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.
Shure's new BLX Series wireless systems put the power in your hands. With robust features, simplicity of operation, rugged tour-ready construction, and Shure's legendary sound quality, BLX systems make it easy for anyone to own the gear that helps you own the stage.
