The Electro-Voice PC Boundary is a professional low-profile multi-pattern boundary condenser microphone designed for conference rooms, boardrooms, meeting tables, and sound reinforcement applications. Its dual-capsule back-electret design offers four selectable polar patterns: omnidirectional, cardioid, supercardioid, and figure-8, providing flexible coverage for different acoustic environments. Featuring advanced RF/GSM shielding, consistent microphone voicing across all four patterns, and a switchable high-pass filter, it delivers clear, natural sound reproduction with reduced ambient noise and phase cancellation. The programmable soft-touch mute switch supports push-on/off, push-to-mute, or push-to-talk operation, while the blue LED indicator clearly displays microphone status. Additional features include automatic mixer compatibility, a vibration-damping base pad, and a 10-foot cable terminated with a 3-pin male XLR connector.
