Using Your Microphone; Cleaning - AKG Acoustics PERCEPTION 150 Mode D'emploi

4 Using Your
Microphone
The PERCEPTION 150 is a general-pur-
pose cardioid 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.
• 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 PF 80 pop screen from AKG
between the microphone and vocal-
ist/instrument.
• Keep the microphone dry. Moisture
from blowing or singing directly at the
6
capsule from a short distance, or
extremely high humidity may cause
the microphone to start crackling or
go very quiet due to partial shorting
of the polarization voltage.
• High volume instruments: You can
use this microphone for close-in
recording of very loud instruments
(brass instruments, kick drum, etc.).
Use a pen or similar pointed object to
set the preattenuation switch to the
"-10 dB" position. This switches the
preattenuation pad in, enabling the
microphone to handle sound pressure
levels up to 145 dB.
• Low-frequency noise: To suppress
low-frequency noise such as air con-
ditioning rumble, footfall noise, or traf-
fic sounds, check whether your mixer
provides highpass filters on the micro-
phone channels. If it does, switch the
appropriate highpass filter in.

5 Cleaning

To clean the surface of the
microphone body, use a soft
cloth moistened with water.
