4 Using Your Microphone

The PERCEPTION 170 is a general-purpose 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 mois-
ture problems, place an optional PF 80 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 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 "-20 dB" position.
This switches the preattenuation pad in, enabling
the microphone to handle sound pressure levels
up to 155 dB.
• Low-frequency noise: To suppress low-fre-
quency noise such as air conditioning rumble,
footfall noise, or traffic sounds, check whether
your mixer provides highpass filters on the
microphone 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.
