The Electro-Voice WP-300S is a dynamic, omnidirectional wall plate microphone designed for security monitoring, retail outlets, warehouses, and public-use applications. Its omnidirectional pickup pattern provides accurate area coverage for reliable sound monitoring. Designed for installation in a standard single-gang electrical box, it features a durable front plate with a brushed satin-chrome finish. The integrated double-pole, double-throw switch supports push-to-talk operation and line-shorting capabilities. A rubber shock mount helps minimize unwanted vibration noise.
