Phones for every head.
Talking about headphones, you go for the very best.
So do we.
Although high quality components are a prerequisite for any high qual-
ity product including headphones, it takes more than that to make an
excellent product, right?
In the case of AKG, the difference is more than 55 years of experience
and know-how, painstaking attention to the smallest detail, and our
constant endeavors to create better products that lead to future-
oriented headphone technologies.
We do not follow short-lived trends, but strive to develop true audio in-
novations. Countless awards and more than 1,400 international patent
applications attest that this has been a good strategy. The important
thing for us is to make sure you will be satisfied with our products and
services for many years.
Curious?
Why don’t you try our headphones and compare them against other
models. I am sure you will find that AKG headphones do not just re-
produce audio but make you e n j o y what you hear. That’s the differ-
ence.

“Pioneering spirit” best characterizes the ambitious work of AKG founders Dr.
Rudolf Görike and Ing. Ernst Pless. After the war, people went to the movies
seeking distraction from the stress of post-war life, so Rudolf Görike built movie
projectors and loudspeakers, while Ernst Pless used his rucksack and bicycle
to deliver the goods to constantly growing numbers of customers. Their very
first customer was unable to pay in cash so he settled the bill in food, fresh
from the black market.
AKG history
1953
When AKG was established in 1947, the company headquarters were located
in a basement in the suburbs of Vienna. Before long, many AKG microphones
were in use, mainly at radio stations, in the-
aters, on small stages, and at jazz clubs.
In the early 1950s, the two founders of AKG
made their business breakthrough with
completely new technologies. The micro-
phones of that era had a strangely shrill and
hollowsound,andAKGtechnologyaddedwarmthandfullnesstomicrophone’s
sound.
In 1953, the first AKG dynamic microphone in the world became an interna-
tional success, and the first large-diaphragm condenser microphone with re-
motely selectable polar patterns set new standards for professional micro-
phones. Almost every major radio or recording studio including BBC London,
one of the first buyers, used these microphones.
1967
1969
The following years saw numerous new developments. Many innovations of
that period are still in use today. The K 10 headphones used by the European
Parliament are but one example.
AKG research engineers have always loved exotic challenges. One of those
was a real-life test of hydrophones for the Austrian deep-sea scientist Hans
Hass and AKG designers were happy to
spend days swimming and diving at the “Di-
ana Bad” indoor pool in downtown Vienna
that was very popular in those days. The
AKG team also fulfilled the very special
wishes of Herbert von Karajan. They had to
hide all the microphones at the first post-
war Salzburg Festival because the maestro had decreed that the audio equip-
ment must be totally invisible to the audience.
1978
1987
1991
1996
2001
2003
2004
The company expanded and patents were applied for in rapid succession.
AKG supplied microphones to major tape recorder manufacturers including
Philips, Grundig, Uher, Loewe and others. Portable reverberation units created
a new market in the 1960s and 1970s. Telephone transducers soon became
a rapidly growing product line. This period also saw the advent of digital tech-
nologyandAKGmadeitssuccessful“digitaldebut”atthe1980OlympicGames
in Moscow.
As early as 1974, AKG built the first wireless headphones. At that time, con-
sumers were skeptical and many felt the new technology was too complicated.
In the late 1980s, AKG launched the K 1000 headphones that were a dramatic
improvement over all earlier attempts at creating a natural, binaural headphone
sound. The audio community was full of praise. The new results of psychoa-
coustic research were presented in exhibitions at the Deutsches Museum in
Munich, the Kunst Museum of Bonn, and even used by the “Audimir” space
flight project. The crew on board the “MIR” performed several tests to exam-
ine the meaning of sound source localization for the humans in space.
The new AKG wireless microphone systems launched in 1996 used a new,
revolutionary technology that was widely acclaimed in the marketplace. Big
name pop artists such as Rod Steward, Peter Gabriel, and Simply Red used
the systems on their tours and AKG became the preferred brand for many other
famous musicians.
At the turn of the millennium, AKG engineers came up with the latest genera-
tion of the HEARO Family, a new line of wireless headphone systems using the
latest surround technology.

A: Sound waves from a given source
arrive at one ear earlier than they do at

Amplitude and phase shifts allow us to
localize a sound source in space.
These four channels are encoded by a
special circuit and recorded in “piggy-
back” fashion on the two stereo tracks.
This allows the signal to be reproduced
in mono, stereo, or (using a decoder)

Ear matching curves
Sound waves from a given source arrive at one ear earlier than they
do at the other, (see also “IVA processing”, para A) because the head,
trunk, and ears cause amplitude and phase shifts. All these changes
can be illustrated by so-called “head-related transfer function”. Since
these curves differ from person to person, everyone perceives sound
in a different way. Ear matching curves are electronic models of outer
ear transfer curves that match the headphone’s sound to the user’s
acoustic perception.
The LOGIC7 decoder uses the localiza-
tion cues contained in stereo signals to
generate a 3-D sound that conveys to
the listener a sense of envelopment in
the sound rather than standing in front
of a pair of loudspeakers. Surround en-

Digital antenna diversity
Diversity reception is normally used in professional wireless micro-
phone systems to ensure perfect reception even under extremely dif-
ficult conditions. An adaptive algorithm makes sure the antenna that
delivers the better signal is always active to prevent dropouts.
Along with the standard 5.1 surround
format, LOGIC7 also provides left and
right side channels, for a total of seven
loudspeaker channels plus one sub-
woofer channel.

In addition, another surround center
channel is added in the headphone

a pair of stereo loudspeakers, with no
extra hardware. All you need is a
stereo amplifier and speakers. The

SOFTWARE
hearo player
Windows users love it: The Windows Media® Player is an impor-
tant tool for playing back music or video programming on the PC.
You can now make this program even more powerful, simply by
downloading a plug-in from AKG that provides 3-D sound through
conventional headphones without expensive peripherals or com-
plicated modifications.
The secret behind this miracle are two technologies that are also
used in the famous wireless surround headphone systems of the
HEARO Family. IVA processing developed by AKG provides a
sound that does not play inside the head as it would with normal
headphone reproduction, but actually seems to come from loud-
speakers placed in your listening room.
The LOGIC7 decoder automatically identifies the input signal for-
mat, monitors it constantly, and simulates up to eight loud-
speakers distributed around the room. It generates the 3-D sound
from almost every input signal format from stereo to the latest
surround standard.
To avoid overburdening your PC with its need for processing
power, the IVA surround processing level can be adjusted auto-
matically or manually. Selectable presets such as MOVIE and
JAZZ provide typical timbres for a more realistic sound.
- Five selectable sound presets (ROCK/POP, CLASSICAL, JAZZ, MOVIE,
NORM) let you match the HEARO Player sound to your personal pref-
erences.
The Hearo Player is a real bargain for those who are looking for a
way to enjoy surround sound from their PC at home or notebook
computer when traveling but do not want to invest in extra hard-
ware or throw away their favorite headphones.

TV
HARDWIRED
Loud and soft are highly
subjective terms.
This is why TV often causes quarrels among
friends or within the family. What sounds soft to
one person may be too loud for the next.
Of course, the volume should be set so that every-
body gets all the dialog but turning the volume up
does not necessarily mean the dialog becomes
any clearer and certainly won’t create a pleasant,
relaxed mood.
k 71 tv
These cost-efficient TV headphones feature a speech-optimized
sound and extra-long cable (20 ft. / 6 m). They are extremely light
and comfortable to wear. A control box provides separate left and
right volume controls. The k 71 tv has a dual-channel mode, too.
Sounds familiar?
The reasons are simple.
Everybody perceives sound differently, and your
left ear may be more sensitive than your right ear.
This means that sometimes it would be better if
the sound were a little louder at one ear than it is
at the other.
Another reason is that most headphones are de-
signed for music reproduction. If you just turn up
the volume of your TV set, the ambient sounds and
music become louder too so you won’t hear the
actors’ voices any better.
Long cable. Close-in sound.

You can see at first sight that these are special headphones. The Balance Series headphones have indeed been designed for lounging
on the sofa in front of the TV. Designed for couch potatoes, these wireless headphones are true stress-killers. Optimized for speech re-
production and featuring volume and balance controls, they make watching and listening to TV a highly comfortable experience, par-
ticularly, if your partner is less keen on listening to the sound of your favorite program. Another convenient feature is the automatic on/off
switch: the headphones will switch on automatically when you put them on and off as you take them off.

k 216 afc
The balance k 122 ir uses infrared transmission that depends on
a direct line of sight between the transmitter and receiver. Wher-
ever you can see the transmitter, you can move about as you like
and receive a clean signal.
The balance k 216 afc uses RF (radio) transmission. An Auto-tun-
ing button causes the receiver to tune automatically to the trans-
mitter frequency. You can move about freely inside your house or
garden while listening, because the radio signal penetrates walls
and ceilings.

An ideal diaphragm should combine
high compliance around the perimeter
with a piston-like motion in the center.
The patented Varimotion diaphragm
from AKG does exactly that. It is thicker
in the center than around its perimeter
so it moves like a piston and is immune
to partial oscillations. The result is ab-
solute accuracy, better imaging and
clarity at high frequencies. Being thin-
ner around the rim, the so-called move-
ment zone, the diaphragm will vibrate
more easily to provide a very powerful
bass range.

“The K 1000 from AKG have been
in production for ten years and
still provide exemplary clarity.”
REFERENCE CLASS
k 1000
Theonlythingthek1000 haveincommonwithconventionalhead-
phones is that you wear them on your head. They are the reward
for the many years AKG engineers spent searching for the ulti-
mate natural, spacious sound.
The k 1000 is a totally open design. Small leather pads hold the
speakers a small distance away from the ears, creating a defined
acoustic space.
ers would. On the inside, too, the k 1000 are totally different from
any other kind of headphones. Driven by dedicated VLD magnet
systems, minimum-friction multi-layer diaphragms provide plane-
wave sound fields in front of the ears. The sound field is subjected
only to the changes and reflections caused by the anatomy of the
user’s outer ears. This is the most natural way of headphone lis-
tening.
This is the visible aspect of the design that creates the same nat-
ural, binaural perception of sound as a pair of stereo loudspeak-
Small wonder that the k 1000 were chosen “Headphones of the
Year” more than once.
Incredibly natural, spacious sound.
k 1000
Top-of-the-line, fully professional headphone/monitor system
- Top-class reference headphones, ideal monitor headphones
for studio use.
- Proven AKG self-adjusting headband and swiveling earphones
(for adjusting the angle between speakers and ears) ensure
excellent comfort.
- Equivalent to a pair of high quality loudspeakers worn on your
head, its speakers “float” in front of the ears.
- Totally open design using minimum-friction multi-layer
diaphragms and VLD (Ventilated Linear Dynamic) magnet
systems for binaural sound.
- Each k 1000 system is individually tested and numbered, and
comes in a wooden box.
- Connecting cable with 4-pin XLR connector and stripped-
and-tinned leads for connection to the loudspeaker terminals
of your amplifier/receiver.
- Leather pads keep speakers at a defined distance from the
ears, and retractable support pads allow for individual adjust-
ment to every head shape.
- Frequency range: 30 Hz to 25 kHz.
