microphone neartransmitter stationsand along
with wireless microphones or other communi-
cations equipment. The extremely rugged,
heavy body and sturdy front grill protect the
microphone from damage from tough handling
on stage.
High headroom, minimum distortion:
Capable of handling sound pressure levels up
to 150 dB (PERCEPTION 120) or 155 dB (PER-
CEPTION 220) without introducing perceptible
distortion and built to resist high temperatures
andhumidity,the microphonewillgive excellent
results in a wide range of applications.
Bass cut filter: Selector 1 on the microphone
front (refer to fig. 1) further reduces low-end
distortion caused by footfall or wind noise, etc.
The filter also minimizes the proximity effect
that close-in miking from less than 4 inches
causes in any unidirectional microphone. The
filter rolls off at 12 dB/octave from 300 Hz
downward.
Switchable preattenuation pad: Selector 2
on the microphonefront (refer to fig.1) lets you
increase the headroom by 20 dB for distortion-
free close-in recording.The preattenuation pad
prevents the microphone's output level, partic-
ularly at low frequencies, from overloading the
miniature transformers used in many mixer
input stages, etc.
