General Description:

PolarChoice Series:

PC Boundary

Multi-Pattern

Boundary Microphone

Key Features:

Selectable polar pattern to easily adapt
to different acoustic environments.
Choose between omni, cardioid,
supercardioid or figure 8.

Exceptional sound quality with EV’s
proven PolarChoice design.

Consistent microphone voicing across
all four patterns.

Easy to use mute switch. Can be
programmed to operate as either latching
on/off or momentary push-to-mute /
push-to-talk.

Disassembly of the mic isn’t required to
change switch functions or for use with
automatic mixers.

Compatible with echo cancellation for
conference applications.

High visibility blue LED clearly displays
mic status to the user and can be
remotely controlled in automatic mixer
mode.

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. 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 /
pushoff, 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.
