Shure GLXD24/B58A Digital Wireless Handheld Microphone System with Beta 58A Capsule

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 automatic frequency management with true digital diversity for a rock-solid wireless signal with exceptional digital audio clarity.
The GLXD24/B58A combines digital audio clarity with reliable wireless performance, automatic frequency management, and intelligent battery rechargeability in a system that's convenient to travel with, simple to operate, and ready to go at the push of a button. You can run up to four mics simultaneously in typical settings and up to 8 mics under controlled Wi-Fi conditions.
The transmitter provides up to 16 hours of operation on an SB902 rechargeable lithium-ion battery with a transmission range up to 200'.
Digital Audio Clarity for Vocal and Speech Applications
Crystal-Clear Audio
The system transmits audio with a flat, 20 Hz to 20 kHz frequency response and 120 dB of dynamic range, leaving the sound of your mic unaffected by the wireless components.
Beta 58A Supercardioid Mic Capsule
The Beta 58A dynamic capsule is designed for close-up vocals, with brightened midrange and bass roll-off to control proximity effect. The capsule features a supercardioid polar pattern that ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration.
