the manufacturer’s instructions, and should use a mounting accessory
recommended by the manufacturer.
9. Cart - A product and cart combination should be moved
with care. Quick stops, excessive force, and uneven surfaces
may cause the product and cart combination to overturn.
10. Ventilation - Slots and openings in the cabinet are provided for
ventilation to ensure reliable operation of the product and to protect it
from overheating. These openings must not be blocked or covered. The
openings should never be blocked by placing the product on a bed,

that they are not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to cords at plugs,
convenience receptacles, and the point where they exit from the
product.
13. Mains Plug - Where the mains plug or an appliance coupler is used
as the disconnect device, the disconnect device shall remain readily
operable.
14. Outdoor Antenna Grounding - If an outside antenna or cable system
is connected to the product, be sure the antenna or cable system is
grounded so as to provide some protection against voltage surges
and built-up static charges. Article 810 of the National Electrical Code,
ANSI/NFPA 70, provides information with regard to proper grounding
of the mast and supporting structure, grounding of the lead-in wire
to an antenna discharge unit, size of grounding conductors, location
of antenna discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installer’s attention to Section 820-40
of the NEC which provides guidelines for proper grounding and, in particular, specifies
that the cable ground shall be connected to the grounding system of the building, as
close to the point of cable entry as practical.
15. Lightning - For added protection for this product during a lightning
storm, or when it is left unattended and unused for long periods of
time, unplug it from the wall outlet and disconnect the antenna or
cable system. This will prevent damage to the product due to lightning
and power-line surges.
16. Power Lines - An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light or power circuits,
or where it can fall into such power lines or circuits. When installing an
outside antenna system, extreme care should be taken to keep from
touching such power lines or circuits as contact with them might be
fatal.
17. Overloading - Do not overload wall outlets, extension cords, or
integral convenience receptacles as this can result in a risk of re or
electric shock.
18. Flame Sources - No naked ame sources, such as lighted candles,
should be placed on the product.
19. Object and Liquid Entry - Never push objects of any kind into this
product through openings as they may touch dangerous voltage
points or short-out parts that could result in a re or electric shock.
Never spill liquid of any kind on the product.
20. Headphones - Excessive sound pressure form earphones and
headphones can cause hearing loss.
21. Damage Requiring Service - Unplug this product from the wall
outlet and refer servicing to qualied service personnel under the
following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally by following the
operating instructions. Adjust only those controls that are covered
by the operating instructions as an improper adjustment of other
controls may result in damage and will often require extensive
work by a qualied technician to restore the product to its normal
operation.
e. If the product has been dropped or damaged in any way.
f. When the product exhibits a distinct change in performance-this
indicates a need for service.
22. Replacement Parts - When replacement parts are required, be sure

THANK YOU FOR CHOOSING NAD.
The M12 Digital Preamp DAC is a technologically advanced and highly
capable product — yet we have invested great eort in making it simple
and easy to use. The M12 is an ultra-high resolution digital audio hub that
interfaces to musical sources and renders the digital or analog source
perfectly to power ampliers and active loudspeakers.
Overall 24 bit accuracy is guaranteed by the 35 bit data path with 24 bit
coecients and 62 bit accumulation which is dithered back to 35 bits after
DSP functions. And because of the super high resolution, even 24 bit les
are processed without truncation or loss of information.
As with all our products, NAD’s “Music First” design philosophy guided the M12’s
design. The M12 delivers a range of genuinely useful options using powerful

OWNER’S MANUAL.
digital signal processing and superbly accurate digital-audio circuitry. However,
we have also been careful to ensure that the M12 is as musically transparent,
faithful to every detail and spatially accurate as possible, incorporating much of
what we’ve learned from more than a quarter-century’s experience designing
audio, video and home-theater components.
We encourage you to take a few minutes now to read right through this
manual. Investing a little time here at the outset might save you a good
deal of time later, and is by far the best way to ensure that you make the
most of your investment in the M12.

INTRODUCTION
GETTING STARTED
WHAT’S IN THE BOX
Packed with your M12 you will nd
• A detachable mains power cord
• HTRM 2 remote control with 4 AA batteries
• Four pieces of magnetic feet
• Cleaning cloth
• USB ash drive
• Quick Setup Guide
SAVE THE PACKAGING
Please save the box and all of the packaging in which your M12 arrived.
Should you move or otherwise need to transport your M12, this is by far
the safest container in which to do so. We’ve seen too many otherwise
perfect components damaged in transit for lack of a proper shipping
carton, so please: Save that box!
CHOOSING A LOCATION
Choose a location that is well ventilated (with at least several inches to
both sides and behind), and that will provide a clear line of sight, within
25 feet / 8meters, between the M12’s front panel and your primary
listening/viewing position—this will ensure reliable infrared remote control
communications. The M12 generates a modest amount of heat, but
nothing that should trouble adjacent components.
It is perfectly possible to stack the M12 on top of other components, but
the reverse usually should be avoided.
RESTORING M12 TO ITS FACTORY DEFAULT SETTINGS
1 Press and hold front panel’s “Main” display.
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
2 Select “Factory Reset” display option.
3 Select “Yes” to reset your M12 to factory default settings or “No” if you
decide not to reset your M12.
4 Factory reset is complete when the M12 goes to standby mode.
IMPORTANT NOTE
After factory reset, wait out for at least one minute to switch back the
M12 from standby mode to operating mode. This wait time can be
bypassed by turning OFF/ON the rear panel power switch and then
press Standby button.
