The precision-engineered Beta 87A condenser vocal microphone has a smooth, tailored response for warm, accurate sound. Its supercardioid polar pattern provides maximum isolation from nearby vocalists or instruments. It combines automatic frequency management with true digital diversity for a rock-solid wireless signal with exceptional digital audio clarity.
The GLXD24/B87A 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'.
