Description
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 table top 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.
