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

AKG PERCEPTION 120

/220

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

AKG PERCEPTION 120/220

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

Fig. 3: Microphone front.

PERCEPTION 120 PERCEPTION 220

AKG PERCEPTION 120/220

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.

AKG PERCEPTION 120/220

fier.

4. Cable connectors are seated loosely.

5. Cable is defective.

6. No supply voltage.
