 Audio-Technica’s AT897 is designed for field audio acquisition in film/TV/video production, professional recording,
wildlife recording and broadcast applications. It mounts conveniently on a DV camcorder without adding noticeable heft, and
remains out of the frame even with compact digital cameras. This high-performance short shotgun offers outstanding long-distance
audio pickup due to narrow acceptance angle of line + gradient design. It also features smooth, natural-sounding on-axis audio
quality and excellent off-axis rejection of sound arriving from the sides and rear of mic.
