AT831CH Beltpack Lavaliere Instrument Condenser Microphone

Audio-Technica's AT831cH is a miniature cardioid condenser microphone engineered for close-miking instruments in live sound, house of worship, theatre, and installed audio environments. Terminated with a 4-pin Hirose (cH-style) connector, it integrates seamlessly with Audio-Technica wireless body-pack transmitters, delivering reliable cable-free operation for performers and presenters on the move.

The AT831cH features a precision-machined condenser capsule with a cardioid polar pattern that provides excellent off-axis rejection, minimising feedback and stage bleed in demanding reinforcement scenarios. With a wide frequency response of 40 Hz – 20 kHz, it captures the full tonal character of acoustic guitars, brass, woodwinds, strings, and percussion with exceptional clarity and natural transient detail.
