AT897
The Audio-Technica AT897 is a high-performance short shotgun condenser microphone engineered for film/video production, electronic news gathering (ENG), and specialized broadcast applications. Its mid-length design is optimized to provide tight, long-distance sound pickup while remaining short enough to sit out of the frame when mounted directly onto a professional cinema camera or compact mirrorless/DSLR cage setup.
Key Performance Features
-
Line + Gradient Directionality: Utilizes a highly directional acoustical design combining a condenser capsule with a specialized interference tube. This configuration creates a narrow, focused capture field that isolates on-axis dialogue and acoustic sources while heavily rejecting off-axis ambient room noise, chatter, and reflections.
-
Dual Power Flexibility: Highly versatile across various field configurations:
-
Phantom Power: Runs on 11V to 52V DC phantom power when connected to a professional field recorder, mixer, or cinema camera, maximizing dynamic range ($112\text{ dB}$) and headroom ($129\text{ dB SPL}$).
-
Battery Power: Can operate completely independent of phantom power via a single standard 1.5V AA battery, yielding a massive 1,200 hours of run time for connection to devices with basic XLR inputs.
-
-
Switchable Low-Frequency Roll-Off: Features a recessed high-pass filter switch that activates an $80\text{ Hz}$ low-cut filter ($18\text{ dB/octave}$). This effectively eliminates low-end acoustic interference such as camera handling noise, wind rumble, and HVAC ventilation hums without stripping warmth from speech.
-
Camera-Mount Optimizations: At just $27.9\text{ cm}$ ($10.98\text{ inches}$) long and weighing $145\text{ g}$, it adds minimal mass to boompoles and won't visually crowd a wide-angle lens when used as an on-camera mic.
-
Balanced Low-Impedance Output: Terminated with an integral 3-pin XLR male connector, ensuring noise-free signal transmission over long cable runs.
