With
directivity equal to mics up to
50% longer, the BP4071 has been
specially created to meet the
pickup demands of broadcasting,
film/TV sound, professional
recording, wildlife recording
and theater sound reinforcement.
Particularly useful for miking
dynamic action in film/TV audio
as well as in “spot” miking
techniques in the music studio
or theater, the 15.55"-long
BP4071 provides a low noise
floor and direct-coupled,
balanced output for a clean
signal even in high-output
conditions. Audio-Technica has
pioneered an interference tube
design in the BP4071 that
provides the same directivity as
mics up to 50 percent longer.
