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 Connect: Select "Yes" to automatically enable and connect the iPod
player docked in the linked NAD iPod docking station when Source 4 (the
default iPod source allocation in the M15 HD) is selected. Select "No" if
you do not want a docked iPod to be 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 "0ff".

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.
IMPORTANT NOTICE
The M15 HD is an AV Surround Sound Preamplifier and therefore has
no speakers. The mention of "Speaker(s)" in this manual refers to the
speakers of your external amplifier as interfaced with the M15 HD.

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 Setup and Calibration featured in M15 HD uses a
microphone, along with sophisticated digital electronics built into your
M15 HD, to automatically setup and calibrate the M15 HD to the exact
speakers and speaker placement of your own unique Home Theatre.
The Left Channel of AUDIO 1 IN is the assigned port where the supplied
3.5mm female jack to RCA plug Adapter can be connected. Plug in the
Audyssey microphone into the adapter for Audyssey Auto Calibration.
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 : M15 HD 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.
