Description

Audio Technica AT846/OOmnidirectionalCondenser Boundary Microphone Overview:

The AT846/O is a wide-range condenser microphone with an omnidirectional polar pattern. It is designed for the unobtrusive table, ceiling or panel-mounted applications for high-quality sound reinforcement, teleconferencing, professional recording, television, and other demanding sound pickup applications.

The AT846/O is equipped with UniGuardRFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI). The microphone is RoHS compliant free from all substances specified in the EU directive on hazardous substances.

The microphone should be placed on a flat, unobstructed mounting surface. The small diameter capsule near the boundary eliminates phase distortion and delivers clear high-output performance.

The microphone requires 11V to 52V phantom power for operation. The microphone is enclosed in a heavy-duty die-cast case and protected by a two-layer steel mesh grille. The low-profile housing has a low-reflectance black finish. Isolators are included with the microphone for optional mechanical isolation from the mounting surface.

To mount the AT846/O in a ceiling or tabletop without the isolators, a 20.5 mm diameter hole is required. To mount the AT846/O with the isolators, a 23.5 mm hole is required. Place the isolators on either side of the hole to achieve mechanical isolation from the mounting surface.
