 AUDIO TECHNICA - AT815B LINE AND GRADIENT CONDENSER MICROPHONE Buy Today @ The Sound Professionals, Inc. |
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.
