AT815b Line + Gradient Condenser Microphone (DISCONTINUED)

The AT815b has been updated. Click here for more information on the newest model.

Designed for video production and broadcast (ENG/EFP) audio acquisition, the AT815b provides the narrow acceptance angle desirable for long-distance sound pickup, along with excellent sound rejection from the sides and rear of mic. The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations.
