7 Important Notes
1. Operating switches on or connecting the transmitter to your audio source may cause clicks which at high volume settings may affect your hearing. Therefore, be sure to set the VOLUME control on the headphones to minimum before switching between different sources (tuner, turntable, CD player, etc.) or connecting the transmitter. Listening over headphones at high volume levels, particularly over extended periods of time, may damage your hearing. Your K 306/K 406/K 506 AFC is a radio frequency device that conforms to the strict European standards. For physical reasons that have nothing to do with the quality of the product, extremely strong interference sources may affect reception. In order to maintain interference-free listening pleasure, do not operate your K 306/K 406/K 506 AFC in the close vicinity of radio equipment, cellular telephones, or directly above TV or computer monitor picture tubes (see fig. 11). The supplied connecting cable is long enough to allow the transmitter to be placed at a safe distance from interference sources. Interference caused by other users of the 864 MHz LPD band are beyond AKGs control.

SURROUND FOR TV / HOME THEATER / HI-FI
Authentic theater surround sound.
Welcome to digital Cloud 9. The hearo 888 digital is a digital surround personal listening system with the kind of wireless headphones that high-end enthusiasts have been waiting for. Digital radio transmission and digital antenna diversity circuitry afford virtually noise and dropoutfree reception. Incredible as it may seem, the hearo 888 digital actually provides the same audio quality as comparable hardwired headphones. Patented IVA processing makes the headphone sound seem to come from loudspeakers, while the integrated Dolby Surround Pro-Logic and LOGIC7 surround decoders add surround sound signals. So, if you are looking for headphones that are equally good at dramatic movie sound effects, crystal-clear dialog, accurate music reproduction as well as the most delicate violin sound, the quietest piano notes, or the most ethereal guitar overtones, then the Hearo 888 digital is the best choice for your discriminating ears.
In short, IVA processing provides a perfectly natural, spatial (binaural) sound through headphones.
Digital transmission ensures pristine C 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 TV sets or computers.
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.
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 headphones sound to the users 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.
VMAx provides surround sound from a pair of stereo loudspeakers, with no extra hardware. All you need is a stereo amplifier and speakers. The VMAx processor simulates the envelopment of surround sound.
- Five selectable sound presets (ROCK/POP, CLASSICAL, JAZZ, MOVIE, NORM) let you match the HEARO Player sound to your personal preferences. - Automatic or manual matching of IVA processing level to available computing power.
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.

UNIQUE AKG FEATURES Self-adjusting headband The headband automatically adjusts to your head to ensure a perfect fit. The headband also takes the weight of the headphone off of your ears and distributes it on top of your head. 3 in 1 The transmitter serves as a storage cradle and battery charger for the headphones (except k 105 uhf ). As soon as you place the headphones on the transmitter cradle, battery re-charging starts automatically. High-capacity rechargeable batteries The supplied batteries have a long life, with no risk of overcharging and minimum memory effect. Speech-optimized response AKG TV headphones boost the frequency range of human speech. Therefore, dialogue will be more intelligible amid the ambience, sound effects, and music, making it easier to catch all the subtle nuances of your favorite actors voice. Balance control Everybody perceives sound differently, and there may even be differences in sensitivity between your left and right ears. The balance control lets you adjust left and right volumes for an optimally balanced sound. Auto-tuning function Pressing the Auto-tuning button causes the headphones to tune automatically to the frequency selected on the transmitter. Patented AKG Varimotion diaphragm The diaphragm is the most important part of the speaker capsule. 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. The result is absolute accuracy, better imaging and clarity at high frequencies. Being thinner around the rim, the diaphragm will vibrate more easily to provide a very powerful bass range.
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 wont 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 wont 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.

The balance k 122 ir uses infrared transmission that depends on a direct line of sight between the transmitter and receiver. Wherever 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-tuning button causes the receiver to tune automatically to the transmitter frequency. You can move about freely inside your house or garden while listening, because the radio signal penetrates walls and ceilings.
A new way of listening. No cable.

Headphones for special applications Self-adjusting headband Gold-plated screw-on jack plug and detachable cable Replaceable ear pads For DJ and mixing use with plug-in cable PORTABLE
UNIQUE AKG FEATURES Self-adjusting headband The headband automatically adjusts to your head to ensure a perfect fit. Gold plated Vario jack plug matches both 1/4 and mini-TRS jacks. The single, 99.99% oxygen-free cable provides loss-free signal connection for years of useful life. Plug-in cable with high quality miniXLR connector for easy cable replacement. Optional accessories: EK 500 S coiled headphone cable (5 m/16 ft. long; mini jack plug; mini XLR plug for connection on headphones) EK 300 headphone cable (3 m/10 ft. long; mini jack plug; mini XLR plug for connection on headphones) Replaceable ear pads are made of breathing, skin-compatible material and easy to clean. Patented AKG 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-m 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 best choice for tough use in loud environments. DJs love these rugged headphones that allow for comfortable single-ear monitoring and the incredible amount of isolation delivered by these closed-back earphones. And it goes without saying that the k 171 studio deliver exactly the kind of powerful sound a DJ needs.
Minimum leakage and ambient noise reduction are important requirements for monitoring in radio, TV, and recording studios. At the same time, these circum-aural headphones sound great and are light and easy to use. What makes them a first choice among studio engineers is their accurate response and the auto-shutoff feature that mutes the headphones when the user takes them off.
- Varimotion XXL speakers for ultimate accuracy. Crisp sound even at high volume levels. - High efficiency and wide dynamic range, a good choice for portable use. - Single, plug-in, easily replaceable cable with mini-XLR connector. - Frequency range: 18 Hz to 24 kHz.
For technical explanations, see page 22.
Although an open-back design, the K 240 suppressed ambient noise quite efficiently Soundwise, they were the powerful kind, but still felt very agile. Perhaps a little reserved at the high end, they provided a beautifully chiseled mid range.

These headphones are actually breathing music; rarely does a pair of headphones create such an accurate bass foundation, and no other model achieves this feat without stifling your ears.
Ranking Top class.
The K 1000 from AKG have been in production for ten years and still provide exemplary clarity.
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 users 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.
