The diaphragm is the most important part of the speaker capsule. Acoustical engineers require this extremely thin piece of foil to perform the most spectacular feats. High-performance cable with 1/4" jack plug The single, 99.99% oxygen-free cable provides consistently excellent audio and is terminated in a 1/4" jack plug for connection to any 1/4" headphone output. Self-adjusting headband The headband optimally adjusts to your head to ensure perfect fit. 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. Replaceable ear pads are made of breathing, skin-compatible material and easy to clean. Being thinner around the rim, the so-called movement zone, the diaphragm will vibrate more easily to provide a very powerful bass range. 7 HOME ENTERTAINMENT Experience pure perfection!

Left and Right are the same two channels used for hi-fi 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. t e r u o i Up to now, the latest development by the innovative engineers at LEXICON was only used in highquality, 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. SURROUND 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 of loudspeakers. Binaural sound: A Sound waves from a given source arrive at one ear earlier than they do 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 TV sets or computers. 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. 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. 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. VMAx 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. 29 HOME ENTERTAINMENT HIGH-END Completely digital wireless headphone system with Dolby Digital decoder for audiophile individualists. hearo 999 audiosphere II Integrated Dolby Surround Pro Logic and Dolby Digital decoders Wireless eight-channel surround headphone system with digital radio link for use with high-end systems hearo 888 digital Integrated Dolby Surround Pro Logic and LOGIC7 surround decoders Wireless eight-channel surround headphone system for TV, home theater, hi-fi use hearo 787 surround Integrated Dolby Surround Pro Logic and LOGIC7 surround decoders 30 SURROUND • For TV/video/DVD/DVD(A)/Hi-fi/ (SA)CD/PC/game consoles • Accepts analog and digital input formats • Selectable surround and stereo modes.
