P420
The P420 is a general-purpose multi-pattern microphone for recording,
broadcast, and onstage use.
Every instrument radiates its sound in a specific way. Therefore, to get the best
sound it is crucial to experiment with microphone placement.
Whichever polar pattern you selected, it
may be good to know which way the
transducer axis is facing: the front of the
microphone is the side of the body with
the AKG logo and polar pattern selector
(1) on it.
When recording wind instruments or
vocals, make sure not to blow or sing
directly into the microphone.
To avoid unwanted wind and pop noise or
moisture problems, place an optional
PF80 pop screen from AKG between the
microphone and vocalist/instrument.
Keep the microphone dry. Moisture
from blowing or singing directly at the
capsule from a short distance, or
extremely high humidity may cause the
microphone to start crackling or go very
quiet due to partial short circuits in the
polarization voltage.
If you use the microphone in the open
air, use an optional AKG W4000 windscreen to protect the microphone
from moisture and reduce wind noise.
High volume instruments: You can use this microphone for close-in
recording of very loud instruments (brass instruments, kick drum, etc.).
Just switch the preattenuation pad in to increase the microphone's
capability of handling sound pressure levels to 155 dB.
Low-frequency noise: To suppress low-frequency noise such as air
conditioning rumble, footfall noise, or traffic sounds, switch the bass cut
filter in.
