User manual AKG HEARO 999 AUDIOSPHERE PROCESSOR MOUNTING DRAWING

[. . . ] For other products and distributors worldwide see our website: http://www. Never place the equipment near heat sources such as radiators or electric heaters or expose it to direct sunlight, excessive dust, humidity, rain, temperatures below freezing, or impacts. Never use petroleum-based cleaners or paint thinners to clean the equipment. When scrapping the equipment, separate the case, circuit boards, and cables, and dispose of all components in accordance with local waste disposal rules. [. . . ] MOVIE: Simulates the typical sound of theater speakers and is therefore recommended for videos and DVD movies in Dolby Surround or Dolby Digital formats. In VMAx mode, only the speaker spreader function without the sound programs will be available. DYNAMIC: The dynamic range (the difference between the loudest and softest passages) of Dolby Digital encoded input signals may sometimes be so great that soft dialogs may become unintelligible. This means that very soft passages will automatically be raised in level while very loud passages are attenuated. With the DYNAMIC switch IN, the full dynamic range of the input signal is preserved and the green LED next to the switch illuminates. COAXIAL: RCA input jack for an optional coaxial cable for interfacing with a digital audio source with a coaxial output. OPTICAL: Input connector for the supplied fiber optical cable for interfacing with a digital audio source with an optical output. You may use the HEARO 999 AUDIOSPHERE either free-standing or install it in a 19" rack using the optional RMU 60 rack mount kit. You can connect the HEARO 999 AUDIOSPHERE to any analog headphones output (mini jack or 1/4" jack), to the LINE or REC output of your amplifier, or to an optical or coaxial digital output. Before connecting the HEARO 999 AUDIOSPHERE to your audio source, switch power to your audio source OFF. Plug the red RCA connector (right channel) on the supplied RCA/jack cable into the red LINE IN RIGHT jack (14) and the white RCA connector (left channel) into the white LINE IN LEFT jack (14) on the HEARO rear panel. If the headphones output on your equipment is a 1/4" jack, plug the supplied mini jack to 1/4" adapter onto the mini jack. Before connecting the transmitter to your audio source, switch power to the audio source OFF. Use a stereo RCA cable (not supplied) to connect the white LINE OUT L or REC OUT L jack on your audio source to the white LINE IN LEFT jack (14) on the HEARO rear panel and the red LINE OUT R or REC OUT R jack to the red LINE IN RIGHT jack (14). Use an optional coaxial cable (mono RCA cable) to connect the coaxial output on your DVD or CD player, digital TV set, or other equipment to the COAXIAL jack (16) on the HEARO rear panel. If the DIGITAL IN switch (17) is IN, push it once to activate the coaxial input. Use the supplied fiber optical cable to connect the optical output on your DVD or CD player, digital TV set, or other equipment to the OPTICAL jack (18) on the HEARO rear panel. If the DIGITAL IN switch (17) is OUT, push it once to activate the optical input. You can connect each digital input to a digital audio source and use the DIGITAL IN switch (17) to toggle between the two audio sources. Use the supplied RCA cable to connect the white "TAPE IN", "AUX IN", or "PLAYBACK IN" jack on the amplifier to the white LINE OUT LEFT jack (15) and the red "TAPE IN" , "AUX IN", or "PLAYBACK IN" jack on the amplifier to the red LINE OUT RIGHT jack (15) on the HEARO rear panel. Refer to the operating manual of your amplifier for instructions on how to listen to and mute the signal at the TAPE", "AUX", or "PLAYBACK" input. On most amplifiers, you can push the "TAPE MONITOR" switch IN to listen to the processed signal and OUT to cut the processed signal. [. . . ] Make a list of the three or four ear matching curves where you perceived the smallest change in sound compared to the unprocessed test signal, and which you felt sounded the most natural. Use the EARS selector (10) to compare the ear matching curves on your shortlist with one another. Make a list of those ear curves where the signal most closely approximated a "point source" (a sound source of zero width). For this test, it makes no difference whether you perceive the signal inside or outside your head. [. . . ]
