With an
overall length of just 9.17” and
weight of just 3.5 oz, this
microphone adds virtually no
heft to the end of a fish pole
or the top of a minicam. Through
the use of an innovative
Audio-Technica design, the
interference tube of the BP4073
provides a narrow acceptance
angle, effective for
long-distance pickup. The highly
directional mics offer low
self-noise and are fully
RoHS-compliant – free from all
substances specified in the EU
directive on the reduction of
hazardous substances (RoHS).
