Product Description
Shure MXA920AL-R Round Ceiling Array Microphone (Aluminum)
Overview
The MXA920 is the premier ceiling array microphone for contemporary meeting spaces. Automatic Coverage technology covers up to a 30 x 30 ft (9 x 9 m) area automatically, or place coverage in specific areas for more precise control of audio capture. With next generation array architecture for enhanced directional pickup and more natural speech, the MXA920 is even easier to use and faster to deploy than the MXA910 for AV conferencing, camera tracking, voice lift, or sound reinforcement.
COVERAGE WHERE YOU WANT IT
Automatic Coverage technology captures up to a 30 x 30 foot (9 x 9 m) area automatically for great sound out of the box. You can also place coverage areas in specific locations to limit audio capture to seating areas, a podium, or whiteboard.
SEAMLESS INTEGRATION
Next-generation array architecture delivers more directional pickup at low frequencies for more natural sounding voice. Onboard IntelliMix DSP with automatic mixing, echo cancellation, noise reduction, and automatic gain control provides a pristine audio mix.
FITS YOUR ROOM DESIGN
Square or round form factors suit your interior design. Choose white, black, or aluminum finish (square available in white only), or paint to match room aesthetics. Versatile hardware options support in-ceiling, on-ceiling, pole, or wirerope mounting.
READY FOR ANYTHING
Camera Tracking: Precise talker localization reports the position of simultaneous talkers for more accurate camera tracking.
Voice Lift: Highly directional pickup allows audience members across the room to interact without the need for roving microphones.
Sound Reinforcement: Precise coverage control enables presenters to be amplified without lavalier or gooseneck microphones
