In the summer of 2002, nearly one billion people were listening to AKG.

Maybe you were one of them. Remember the opening ceremony of the soccer world cup in Seoul? The sound system there used the latest wireless technology from AKG.

One reason was that AKG is one of the world’s leading manufacturers of headphones and microphones plus AKG audio equipment has been in use in countless concert halls, conference rooms, broadcast and recording studios, theaters, and rock concert venues all over the world.

A lot of mobile phones and a growing number of cars including the new Maybach ultra-luxury sedan from DaimlerChrysler use AKG technology.

So, whether you own a Maybach or not, treat your ears to tailor-made

AKG sound and experience the finest reproduction available.

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 quality 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 futureoriented headphone technologies.

We do not follow short-lived trends, but strive to develop true audio innovations. 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 reproduce audio but make you e n j o y what you hear. That’s the difference.

“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.

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 theaters, 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 microphones of that era had a strangely shrill and hollow sound, and AKG technology added warmth and fullness to microphone’s sound.

In 1953, the first AKG dynamic microphone in the world became an international success, and the first large-diaphragm condenser microphone with remotely selectable polar patterns set new standards for professional microphones. Almost every major radio or recording studio including BBC London, one of the first buyers, used these microphones.

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 “Diana 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 postwar Salzburg Festival because the maestro had decreed that the audio equipment must be totally invisible to the audience.

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 technology and AKG made its successful “digital debut” at the 1980 Olympic Games in Moscow.

As early as 1974, AKG built the first wireless headphones. At that time, consumers 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 psychoacoustic 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 examine 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 generation of the HEARO Family, a new line of wireless headphone systems using the latest surround technology.

And the story goes on …

TECHNOLOGY

Dolby Surround Pro-Logic decoder

Movie soundtracks are usually mixed down to four channels. Left and Right are the same two channels used for hifi stereo. The third channel is the Center channel projected from above or below the video screen. The fourth channel is called “surround” or “rear” and is usually projected by two loudspeakers placed behind the listeners.

These four channels are encoded by a special circuit and recorded in “piggyback” fashion on the two stereo tracks.

This allows the signal to be reproduced in mono, stereo, or (using a decoder) through four separate channels. For surround reproduction, the signal needs to be decoded. This is the job of the Dolby

Surround decoder.

Dolby Digital decoder

The digital multi-channel format of Dolby

Laboratories, Inc. used in advanced commercial theater equipment is the most widespread digital surround standard for DVDs, laser discs, and digital

TV. The distinguishing feature of Dolby

Digital is that all tracks (five audio tracks plus one subwoofer track) are stored separately in digital form. These discreet channels allow an optimized spatial sound to be generated that can be processed in the digital domain by IVA without any degradation of sound quality.

IVA processing

Patented AKG IVA processing for spatial sound is the heart of each HEARO surround headphone system. IVA provides natural (binaural) imaging through headphones in a similar way as if you were listening to a pair or loudspeakers.

Binaural sound

A: Sound waves from a given source arrive at one ear earlier than they do at the other, and they “look” different, too.

Amplitude and phase shifts allow us to localize a sound source in space.

B: Headphones usually eliminate these important amplitude and phase shifts. Sound sources are perceived as being inside the head rather than in the room.

C: IVA processing developed by AKG adds to a stereo signal the amplitude and phase shifts that are necessary to create a sense of natural, spatial, “outside the head” imaging.

In short, IVA processing provides a perfectly natural, spatial (binaural) sound through headphones.

Digital transmission

Digital transmission ensures pristine surround sound with a CD-level dynamic range and no perceptible noise.

Digital radio links are immune to interference and “jamming” from devices emitting RF radiation such as

Eight-channel surround

Eight-channel surround is an improved version of the internationally accepted five-channel format. The new format models eight virtual loudspeakers distributed around the room. The result is an incredibly spacious sound. Eight-channel surround requires a

LOGIC7 decoder.

➝

LOGIC7 decoder

Up to now, the latest development by the innovative engineers at LEXICON was only used in high-quality, high-end processors. Now, the unique advantages of the LOGIC7 decoder are available for headphones for the first time.

The LOGIC7 decoder automatically identifies the input signal as mono, stereo, or surround encoded and processes the signals appropriately.

The LOGIC7 decoder uses the localization 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 encoded signals are reproduced exactly as defined in the mix.

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 subwoofer channel.

In addition, another surround center channel is added in the headphone mode. In conjunction with IVA processing, LOGIC7 provides its full performance level with eight virtual loudspeakers.

The result is far more natural and accurate imaging.

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.

Digital antenna diversity

Diversity reception is normally used in professional wireless microphone systems to ensure perfect reception even under extremely difficult conditions. An adaptive algorithm makes sure the antenna that delivers the better signal is always active to prevent dropouts.

Windows users love it: The Windows Media® Player is an important 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 complicated 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 loudspeakers placed in your listening room.

The LOGIC7 decoder automatically identifies the input signal format, monitors it constantly, and simulates up to eight loudspeakers 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 automatically or manually. Selectable presets such as MOVIE and

JAZZ provide typical timbres for a more realistic sound.

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 hardware or throw away their favorite headphones.

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 everybody 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.

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 designed 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.

The comfortable TV headphones from AKG have been optimized for speech reproduction and allow you to adjust the left/right volume ratio. They bring a new level of fun to TV watching.

Varimotion diaphragm

The diaphragm is the most important part of the speaker capsule.

Acoustic scientists require this extremely thin piece of foil to perform the most spectacular feats.

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 absolute accuracy, better imaging and clarity at high frequencies. Being thinner around the rim, the so-called movement zone, the diaphragm will vibrate more easily to provide a very powerful bass range.

The audiophile-grade k 501 uses a thicker 80-µm foil with even more stable vibration performance. The diaphragms on the k 501 are hand-selected and feature trapezoidal corrugations that further enhance their excellent acoustic performance.

The undisputed flagship of our reference class and many reviewers’ favorite delivers a spacious, airy sound at the high frequencies, which has earned it an excellent reputation among lovers of classical music. Although the physical difference is minimal, it makes an enor-mous difference for sound purists. The diaphragm is 80 µm thick in its central area for enhanced clarity at high frequencies and thinner around its perimeter for solid, accurate bass response. To further improve the sound, the hand-selected diaphragms are reinforced with trapezoidal corrugations.

REFERENCE CLASS

k 1000

The only thing the k 1000 have in common with conventional headphones is that you wear them on your head. They are the reward for the many years AKG engineers spent searching for the ultimate 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.

This is the visible aspect of the design that creates the same natural, binaural perception of sound as a pair of stereo loudspeakers 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 planewave 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 listening.

Small wonder that the k 1000 were chosen “Headphones of the

Year” more than once.

Incredibly natural, spacious sound.

Top-of-the-line, fully professional headphone/monitor system

- Top-class reference headphones, ideal monitor headphones for studio use.

- 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.

- Leather pads keep speakers at a defined distance from the ears, and retractable support pads allow for individual adjustment to every head shape.

- Proven AKG self-adjusting headband and swiveling earphones

(for adjusting the angle between speakers and ears) ensure excellent comfort.

- Each k 1000 system is individually tested and numbered, and comes in a wooden box.

- Connecting cable with 4-pin XLR connector and strippedand-tinned leads for connection to the loudspeaker terminals of your amplifier/receiver.

- Frequency range: 30 Hz to 25 kHz.
