User manual AKG HEARO 999 AUDIOSPHERE II

[. . . ] Please read the manual before using the equipment!FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Parts 74, 15, and 90 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. [. . . ] VMAx also allows you to increase the virtual distance between closely spaced stereo loudspeakers (e. The processed signal is available at the analog audio output so you can use a standard stereo amplifier to reproduce the VMAx signal. The green LED next to the ON switch lights to indicate the unit is ON. The green LED next to the DIGITAL switch lights to indicate the digital input has been selected. The bi-color LED next to the control indicates the signal level at the input to the audio circuitry: flickering/lighting green indicates optimum level range, red indicates overload. : This four-step rotary switch selects three different channels within the carrier frequency band of the integrated transmitter or switches the transmitter off ("0" position). SURROUND: This five-step rotary switch is located in the signal path between the input stage and the MODE switch. It switches the Dolby decoders on and off or adds one of three different reverb programs to normal stereo signals. the output signal of the SURROUND selector passes through the MODE switch and on to the IVA or VMAx processor or directly to the output. AUTO: This mode automatically activates the Dolby Surround Pro-Logic or Dolby Digital decoder depending on whether a Pro-Logic or Dolby Digital signal is present at the input. One green LED each will light to indicate which decoder is currently active. If a normal stereo signal is present at the input, we recommend that you set the SURROUND selector to "OFF" in order to avoid undesired sonic results. CLUB, HALL, STADIUM: Acoustic simulations of three different venues of different sizes. STEREO: This green LED indicates the following modes: Stereo signal at the input and SURROUND selector (7) in "OFF" position: SURROUND selector (7) in "CLUB", "HALL", OR "STADIUM" position: SURROUND selector (7) in "AUTO" position: MODE selector (9) in "DIRECT" position: STEREO LED off MODE selector (9) in "IVA-PHONES" or "VMAx" position and SURROUND selector (7) in "AUTO" position: 9. MODE: This three-step rotary switch selects the following modes: IVA-PHONES: The IVA processor is active and affects the signal at the PHONES and LINE outputs as well as the signal transmitted to the wireless headphones. In this mode, the green LED below the IVA-PHONES label will be illuminated. DIRECT: In this mode, all signal processors are out of circuit and all controls and indicators to the right of the MODE selector are disabled. You will hear the unchanged stereo input signal in the hardwire and wireless headphones and the loudspeakers STEREO LED on A Dolby Digital encoded signal present at the input will be automatically mixed down to a Pro-Logic encoded stereo signal. vMAx: The VMAx processor derives a 3-D signal for loudspeaker reproduction. In VMAx mode, the green LED above the VMAx label will be illuminated. EARS: The shape of the outer ear changes the waveform of impinging sound in a unique way that differs from person to person. Using headphones defeats these outer ear transfer functions because the sound sources are located immediately in front of the ears. [. . . ] Use the first signal, "Applause", to make a shortlist of the best ear matching curves. The second signal, "Acoustic Guitar Solo", is a pure mono signal (identical signals in the left and right channels) for "choosing the winner". Of course, you may as well use applause and a mono signal rich in transients (such as a solo piece for acoustic guitar) from an existing sound carrier. Make a list of the three or four ear matching curves where you perceived the smallest 4. [. . . ]
