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.
