AT-815b
Long Gun Microphone - Line + Gradient Condenser Microphones
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.
