AT8015 Audio-Technica | Audio-Technica

Line + Gradient Conderser Microphone

AT8015

Designed for video production and broadcast (ENG/EFP) audio acquisition

Provides the narrow acceptance angle desirable for long-distance sound pickup

Excellent sound rejection from the sides and rear of mic

Switchable low-frequency roll-off

Operates on battery or phantom power

The AT8015 requires 11V to 52V DC phantom power or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation.

Output from the microphone’s XLRM-type connector is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot” – positive acoustic pressure produces positive voltage at Pin 2.

An integral 80 Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off. 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.

The microphone is RoHS compliant–free from all substances specified in the EU directive on hazardous substances.
