Selecting Polar Patterns; Cleaning - AKG PERCEPTION 400 User Instructions

• Low-frequency noise: To suppress
low-frequency noise such as air con-
ditioning rumble, footfall noise, or
traffic sounds, switch the bass cut fil-
ter in.

4.2 Selecting Polar Patterns

Each of the PERCEPTION 400's selec-
table polar patterns is virtually frequency
independent so that reflected sound, too
will be reproduced accurately and uncol-
ored.
• Cardioid (center setting): This is a
standard setting for recording and
gives excellent results on all kinds of
voices and a wide range of instru-
ments. Remember to aim the micro-
phone front (see fig. 5 on page 6) at
the sound source.
• Figure eight (left-hand setting): The
microphone will pick up sounds arriv-
ing from the front and rear with equal
8
sensitivity. Use this mode to mic up
the side signal in M/S stereo record-
ing or to record two sound sources
(talkers, instruments) facing each
other. It is also a good choice for
cymbal overhead miking.
• Omnidirectional (right-hand setting):
This is the preferred setting for "all
around the mic" recording, high qual-
ity ambience (audience sound) mik-
ing, or far-field recording in excep-
tionally good-sounding large or small
recording rooms, etc.

5 Cleaning

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