2 Description
2.1 Introduction
Thank you for purchasing an AKG product. This
Manual contains important instructions for setting
up and operating your equipment. Please take a
few minutes to read the instructions below care-
fully before operating the equipment and keep
the Manual for future reference. Have fun and
impress your audience!
The
PERCEPTION 120
and
PERCEPTION 220
are
heavy-duty, rugged condenser microphones built to
the same strict quality standards as all other AKG
products.
The
PERCEPTION 120
uses a 2/3-inch back electret
diaphragm, while the
PERCEPTION 220
is a true
condenser microphone with a 1-inch large dia-
phragm.
Designed on the basis of AKG’s decades of know-
how and feedback from sound engineers around
the world using AKG studio microphones every day,
these general-purpose microphones bring AKG stu-
dio quality to the worlds of recording, live sound,
and broadcasting.
2.2 Features
The
PERCEPTION 120
and 220 share the following
features:
•Cardioid polar pattern: The microphone is
most sensitive to sounds arriving from in front
of it while picking up much less of sounds arriv-
ing from the sides or rear (from monitor speak-
ers or neighboring instruments). This makes
the microphone equally suited for recording
and onstage use.
•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 pres-
sure levels.
•All-metal body: The all-metal body adds to the
rejection of RF interference so you can use the
L

microphone near transmitter stations and along
with wireless microphones or other communi-
cations 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 150 dB (PERCEPTION 120) or 155 dB (PER-
CEPTION 220) without introducing perceptible
distortion and built to resist high temperatures
and humidity, the microphone will give excellent
results in a wide range of applications.
•Bass cut filter: Selector 1 on the microphone
front (refer to fig. 1) 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.
•Switchable preattenuation pad: Selector 2
on the microphone front (refer to fig. 1) lets you
increase the headroom by 20 dB for distortion-
free close-in recording. The preattenuation pad
prevents the microphone's output level, partic-
ularly at low frequencies, from overloading the
miniature transformers used in many mixer
input stages, etc.
2.3 Optional Accessories
•PF 80 studio pop screen
• ST 305 floor stand
•W 4000 external windcscreen

3 Interfacing
3.1 General
Section 3 applies to both the
PERCEPTION 120
and the
PERCEPTION 220
.
The microphone uses a condenser transducer de-
signed for 48-volt phantom powering to DIN 45 596/
IEC 268-15 and needs an external power supply.
3.2 Pinout
The microphone provides a balanced output on a 3-
pin male XLR connector:
Pin 1: ground
Pin 2: hot
Pin 3: cold
3.3 Connecting the Microphone
Refer to fig. 2.
1. Use an XLR cable to connect the microphone to
a balanced XLR input with phantom power.
2. Switch the phantom power on. (Refer to the user
manual of the unit to which you connected your
microphone.)

4 Using Your Microphone
4.1 General Hints
The
PERCEPTION 120
and
PERCEPTION 220
are gen-
eral-purpose cardioid microphones 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.
The following hints apply to both the
PERCEPTION
120
and the
PERCEPTION 220
.
• Refer to fig. 3. The front of the microphone is
the side of the body with the AKG logo on it.
Therefore, always aim the logo at the sound
source you are going to record!
Being a unidirectional (cardioid) microphone,
the
PERCEPTION 120/220
will pick up very little
sound from the rear.
• 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 short circuits in the
polarization voltage.
• If you use the microphone in the open air, use
an optional AKG W 4000 windscreen to pro-
tect 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 in-
crease the microphone’s capability of handling

sound pressure levels up to 150 dB (PERCEP-
TION 120) or 155 dB (PERCEPTION 220).
•Low-frequency noise: To suppress low-fre-
quency noise such as air conditioning rumble,
footfall noise, or traffic sounds, switch the bass
cut filter in.
5 Cleaning
• To clean the surface of the microphone body,
use a soft cloth moistened with water.
