Audio-Technica AT831CW Lavalier Dynamic Microphone

The AT831CW is the wireless-system variant of the AT831R miniature cardioid condenser microphone, terminated with a cW 4-pin connector for direct compatibility with professional wireless bodypack transmitters that use this connector standard. The miniature cardioid capsule and flat frequency response are identical to the AT831R, making the AT831CW equally suitable for both instrument close-miking and vocal lavalier use in wireless configurations without adapter requirements.

cW Termination for Wireless Systems

The cW connector provides direct compatibility with a wide range of professional wireless bodypack transmitters, simplifying wireless system setup and eliminating the need for third-party adapter cables. The same acoustic performance as the standard AT831R is delivered in a configuration immediately ready for wireless integration across diverse production environments.

Miniature Cardioid Versatility

The AT831CW's flat, extended frequency response from 30 Hz to 20 kHz and cardioid polar pattern make it suitable for instrument spot-miking — particularly for acoustic instruments, woodwinds, and drum kit close-miking — as well as lavalier vocal pickup for theatre, television, and live performance applications where a miniature form factor is required.
