Product Overview
The Audio-Technica AT8405A is a snap-in microphone stand clamp designed to mount 21 mm diameter microphones to standard stands. This microphone stand clamp secures slim condenser and instrument microphones for live sound, broadcast, and studio recording applications. It snaps onto compatible mic bodies and threads onto common stands for fast, secure positioning. As a purpose-built mounting accessory, it is the matched clamp for a wide range of Audio-Technica microphones.
Product Description

The AT8405A provides a snap-in mounting solution for microphones with a 21 mm body diameter, holding the mic firmly while allowing quick insertion and removal during setup and changeovers. It is compatible with 5/8-inch-27 threaded stands, the standard thread found on professional microphone stands and boom arms throughout live sound and studio environments. This makes it a direct fit for the most common floor stands, desk stands, and overhead booms used in commercial AV. The clamp serves as a replacement or spare for numerous Audio-Technica microphones, including the AT4021, AT4022, AT4041, AT4049, AT4051, AT4053, AT8015, AT8035, and AT897, among others. For AV integrators and production crews, keeping spare stand clamps on hand prevents downtime when an original mount is lost or damaged. The straightforward design supports repeatable, secure microphone placement across rehearsals, performances, and recording sessions.
