Features

P420

Selectable polar patterns: The microphone's transducer uses a dual
diaphragm. This sophisticated technology allows you to select the optimum
polar pattern (cardioid, omnidirectional, or figure eight) for every
application.

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 155 dB without introducing perceptible distortion and
built to resist high temperatures and humidity, the microphone will give
excellent results in a wide range of applications.


Polar pattern selector: Selector 1 on the microphone front sets the
microphone polar pattern to cardioid, omnidirectional, or figure eight.

Switchable preattenuation pad: Selector 2 on the microphone rear 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.

Bass cut filter: Selector 3 on the microphone rear 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.
