The PC Boundary microphone is a low profile microphone which can be used with standard and automatic microphone mixers. The PC Boundary microphone is part of the EV Polar
Choice series of omnidirectional microphones. Multi-directional Polar microphone
Choice makes it a true "problem solver". With one omnidirectional and three directional polar patterns, Polar microphones
Choice are ideal for almost any installation. Of particular interest is the figure-eight diagram which allows you to eavesdrop on people on opposite sides of the table with just one microphone while providing a significant reduction in ambient noise in the room. The PC Boundary microphone features a large touch-sensitive mute button. The mute button can be configured for mute/mute functions press and talk or mute by pressing. Programming the mute switch is easy without disassembling the microphone. The microphone can also be programmed to operate in real time or to mute when power is first applied (in switch mode). Besides A switch on the bottom of the microphone quickly puts the PC Boundary into auto mixer mode. In this mode the sound is always on. Features: Selectable polar pattern for easy adaptation to varying acoustic environments. Choose between omni, cardioid supercardioid or number 8. Exceptional sound quality thanks to proven Polar design
Choice by EV. Stable microphone sound transmission across all four polar patterns. Easy to use mute switch. Can be programmed to operate either with on/off latching or with instant mute or conversation by pressing. Disassembly of the microphone is not required to change switch functions or for use with automatic mixers. Compatible with echo cancellation for conferencing applications. High Blue LED clearly displays microphone status to the user and can be controlled remotely in auto mixer mode. Characteristics Generation element: double capacitor rear electret.
