Audio-Technica AT8015 Line + Gradient Condenser MicrophoneDesigned for video production and broadcast (ENG EFP) audio acquisition, the AT8015 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.
