Ipod Setup; Speaker Setup; Audyssey Auto Calibration - NAD T785 Owner's Manual

iPod SETUP

The iPod Setup menu allows you to preset the following associated settings when iPod is the selected
source:
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 NAD
iPod docking station when Source 5 (the default iPod source allocation in the T 785) 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 iPod
menu has been left idle (no scrolling or navigation being done) for the specified time out time. For
the "Now Playing" OSD to be shown, there should be a song paused or being played before going
to the iPod menu. You can set the "Menu Timeout" between the range 5s to 60s at 5s increments. If
you do not want for the menu to timeout, select "Off".

SPEAKER SETUP

After connecting all ancillary sources and other combinations, the Speaker Setup menu will guide
you on how to manage and setup your speakers in order to achieve optimum sound acoustics in your
listening environment.
The following are the Speaker Setup Menu sections.

AUDYSSEY AUTO CALIBRATION

It has been shown that many, if not most, surround sound systems are not accurately setup and
calibrated. To be done properly, calibration requires special knowledge and instrumentation that the
average person probably doesn't possess.
The Audyssey Auto Calibration featured in T 785 uses a microphone, along with sophisticated digital
electronics built into your T 785, to automatically setup and calibrate the T 785 to the 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 and
whether a subwoofer and center channel is connected.
• Size: T 785 crossover is set based on each channel's signal handling capability and the subwoofer
crossover 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 speaker
position.
• Polarity: the setup program will detect and notify the user if any speakers are connected
improperly. 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 should
be performed again.
AUDYSSEY MultEQ XT ROOM ACOUSTICS CORRECTION
Sound reflecting from room boundaries can disturb the spatial illusion of surround sound, and can also
distort the tonal balance of the system. Professional Acoustical Engineers often add wall treatments
and even move walls and relocate speakers to improve system performance, but for the average Home
Theatre, this is either too expensive or just not a practical solution.
Audyssey MultEQ XT, using multiple measurements from the actual listening positions, and processing
this information using very sophisticated digital signal processing, is able to "precondition" the signal to
effectively make the walls disappear. This creates a "family size" sweet spot where the sound and spatial
cues are very accurately reproduced.
MultEQ XT is designed to tame room acoustics without changing the sonic character of your
loudspeakers. While it will make the most of whatever loudspeakers you have, it will not make poor
speakers sound like good ones!
Connect the Audyssey microphone jack into the front panel's MP/MIC input and the Audyssey Auto
Calibration wizard will guide you through a simple step-by-step configuration. Once setup and
calibrated, the next greatest improvement in performance is obtained by eliminating the acoustic
interference caused by room boundaries interacting with your speakers.
