EV PC BOUNDARY
MULTI‑PATTERN BOUNDARY LAYER MICROPHONE
The PC Boundary is a very low-profile area microphone that can be used on any surface and with virtually any mic mixer. Featuring multiple on-board polar patterns—three directional and one omni—the PC Boundary is ideal for any installation where premium-grade area coverage is required.
The PC Boundary mic is a low profile microphone that can be used with standard and automatic mic mixers. The PC Boundary mic 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 mic 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 mic, quickly converts the PC Boundary to automatic mixer mode. In this mode, audio is always on.
A large blue LED indicator lights when the mic is active, and can be remotely controlled when the mic is in automatic mixer mode. The PC Boundary mic 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. The PC Boundary mic 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.
