The PC Boundary microphone is a member of the EV PolarChoice series of multi-pattern microphones, and is highly-shielded from RFI/GSM thanks to EV’s exclusive RF Shield technology. The multi-pattern versatility of the PolarChoice microphone makes it a true "problem solver". With one non-directional and three directional polar patterns available, PolarChoice microphones are ideal for virtually any installation. Of particular interest is the figure 8 pattern that allows miking people on opposite sides of a table with only one microphone, while providing a dramatic reduction of ambient room noise.

 

The PC Boundary microphone features a large soft-touch mute button. The mute button can be configured for push-on/push-off, push-to-talk, or push-to-mute functions. Mute switch programming is easily accomplished without disassembling the microphone. The microphone can also be programmed to be either live or muted when power is initially applied (when in toggle mode). Additionally, a switch on the bottom of the microphone, quickly converts the PC Boundary to automatic mixer mode. In this mode, audio is always on. A large blue LED indicator lights when the microphone is active, and can be remotely controlled when the microphone is in automatic mixer mode.

 

The PC Boundary microphone is designed to take acoustic advantage of placing a microphone close to a “boundary” such as conference table. Advantages include reduced phase cancellation and up to 3dB reduction in ambient noise. It also includes a switchable high pass filter and a high-performance vibration-damping pad on the bottom to greatly reduce any vibration induced noise pick-up.
