iPod SETUPThe iPod Setup menu allows you to preset the following associated settings when iPod is the selectedsource:Enabled : Select [Yes] to enable iPod as a Source or [No] to disable it.Auto : Select [Yes] to automatically enable and connect the iPod player docked in the linked NADiPod docking station when Source 5 (the default iPod source allocation in the T 775) is selected.Select [No] if you do not want for the iPod connection automatically connected.Menu Timeout : Set the time for the OSD to revert to the ‘Now Playing’ display when the iPodmenu has been left idle (no scrolling or navigation being done) for the specified time out time. Forthe ‘Now Playing’ OSD to be shown, there should be a song paused or being played before goingto the iPod menu. You can set the ‘Menu Timeout’ between the range 5s to 60s at 5s increments. Ifyou do not want for the menu to timeout, select ‘Off.’SPEAKER SETUPAfter connecting all ancillary sources and other combinations, the Speaker Setup menu will guideyou on how to manage and setup your speakers in order to achieve optimum sound acoustics in yourlistening environment.The following are the Speaker Setup Menu sections.AUDYSSEY AUTO CALIBRATIONIt has been shown that many, if not most, surround sound systems are not accurately setup andcalibrated. To be done properly, calibration requires special knowledge and instrumentation that theaverage person probably doesn’t possess.The Audyssey Auto Setup and Calibration featured in T 775 uses a microphone, along withsophisticated digital electronics built into your T 775, to automatically setup and calibrate the T 775 tothe exact speakers and speaker placement of your own unique Home Theatre.The following measurements are performed:• Detection : Speaker configuration is detected including number of surround speakers andwhether a subwoofer and center channel is connected.• Size : T 775 crossover is set based on each channel’s signal handling capability and the subwoofercrossover is automatically set.• Level : SPL of each speaker is matched within 1dB at the microphone position.• Distance : is accurately set to within 1 foot (30 centimeters) of the microphone for each speakerposition.• Polarity : the setup program will detect and notify the user if any speakers are connectedimproperly. Incorrect polarity can ruin the illusion of realism offered by surround sound.This is a one-time set up, unless speakers are moved or changed, in which case the calibration shouldbe performed again.AUDYSSEY MultEQ XT ROOM ACOUSTICS CORRECTIONSound reflecting from room boundaries can disturb the spatial illusion of surround sound, and can alsodistort the tonal balance of the system. Professional Acoustical Engineers often add wall treatmentsand even move walls and relocate speakers to improve system performance, but for the average HomeTheatre, this is either too expensive or just not a practical solution.Audyssey MultEQ XT, using multiple measurements from the actual listening positions, and processingthis information using very sophisticated digital signal processing, is able to “precondition” the signal toeffectively make the walls disappear. This creates a ‘family size’ sweet spot where the sound and spatialcues are very accurately reproduced.MultEQ XT is designed to tame room acoustics without changing the sonic character of yourloudspeakers. While it will make the most of whatever loudspeakers you have, it will not make poorspeakers sound like good ones!Connect the Audyssey microphone jack into the front panel’s MP/MIC input and the Audyssey AutoCalibration wizard will guide you through a simple step-by-step configuration. Once setup andcalibrated, the next greatest improvement in performance is obtained by eliminating the acousticinterference caused by room boundaries interacting with your speakers.OPERATIONUSING THE T 775 – SETUP MENU0ENGLISH FRANÇAIS ESPAÑOL ITALIANO DEUTSCH NEDERLANDS SVENSKA РУССКИЙ
