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.
- End of table (300°), center of table (360°), or cross table (bidirectional) coverage patterns
- Individual control of each element
- Bi-color status indicator
- Programmable mute switch
- Logic input/output for remote LED and mute control
- CommShield Technology
