Description
The Microflex® Multi-Element Boundary microphone delivers a unique and versatile tool for conference room installations.
Clean and simple in appearance, Multi-Element Boundary mics come in two or three element configurations, combining the coverage of multiple microphones into one small, compact package.
Features:
- End of table (300°), center of table (360°), or cross table (bidirectional) coverage patterns
- Individual audio output for each element
- Bi-color status indicator
- Programmable mute switch
- Logic input/output for remote LED and mute control
- CommShield® Technology
