The Audio-Technica PRO 24-CM camcorder microphone is a lightweight, compact stereo condenser ideal for digital recording with high-fidelity stereo sound. Equipped with an accessory shoe and permanently attached coiled cable, the microphone features a pair of cardioid elements in an X-Y configuration to provide the spatial impact and realism of a live sound field. The microphone is designed for either battery operation or battery-free operation when used with camcorders that provide plug-in power at the mic input. Like all Audio-Technica mics, the PRO 24-CM is rugged; it's built to endure the rigors of field production.
