Description
The P120 and P220 share the following features:

Cardioid polar pattern: The microphone is most sensitive to sounds
arriving from in front of it while picking up much less of sounds arriving
from the sides or rear (from monitor speakers or neighboring
instruments). This makes the microphone equally suited for recording and
onstage use.
Gold-sputtered diaphragm: The diaphragm is made of a plastic foil that
is gold-sputtered on one side only to prevent shorting to the back
electrode even at extremely high sound pressure levels.
All-metal body: The all-metal body adds to the rejection of RF
interference so you can use the microphone near transmitter stations and
along with wireless microphones or other communications 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 (P120) or 155 dB (P220) without
introducing perceptible distortion and built to resist high temperatures
and humidity, the microphone will give excellent results in a wide range of
applications.
Bass cut filter: Selector 1 on the
microphone front 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 6 dB/octave

(P120) or at 12 dB/octave (P220) from 300 Hz downward.
Switchable preattenuation pad: Selector 2 on the microphone front lets
you increase the headroom by 20 dB for distortionfree close-in recording.
The preattenuation pad prevents the microphone's output level,
particularly at low frequencies, from overloading the miniature
transformers used in many mixer input stages, etc.
