THANK YOU FOR CHOOSING NAD.
The M4 Tuner is a technologically advanced and highly capable product
— yet we have invested great eort in making it simple and easy to use.
We have been careful to ensure that the M4 is as musically transparent
and spatially accurate as possible, incorporating much of what we’ve
learned from a quarter century’s experience designing audio and hometheater components. As with all our products, NAD’s “Music First” design
philosophy guided the M4’s design, such that it can condently promise
you both state-of-the-art and audiophile-quality music listening for years
to come.
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 M4, and get the most from this powerful
and exible audio component.
One more thing: We urge you to register your M4 ownership on the NAD
Worldwide Web site:

INTRODUCTION
GETTING STARTED
WHAT’S IN THE BOX
Packed with your M4 you will nd
· An AM loop antenna.
· A FM ribbon-wire antenna with balun.
· A DAB antenna (230V version only)
· A removable AC cable (if you wish, any IEC-standard AC cable of suitable
wattage may be substituted).
· The M4 remote control with 2 (two) AA batteries.
· This owner’s manual.
SAVE THE PACKAGING
Please save the box and all of the packaging in which your M4 arrived.
Should you move or otherwise need to transport your M4, 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 23feet/7
meters, between the M4’s front panel and your primary listening/viewing
position—this will ensure reliable infrared remote control communications.
The M4 generates a modest amount of heat, but nothing that should
trouble adjacent components. It is especially important that sucient
ventilation be provided. If you are contemplating on locating the M4 within
a cabinet or other furniture, consult your NAD audio/video specialist for
advice on providing adequate airow.
ABOUT M4
The M4 Tuner is equipped with DAB (230V version only), XM-input (for
120V version only) and RDS (Radio Data System), bringing a wide range of
information to radio listeners. These are in addition to the normal AM/FM
band reception.
Now in use in many countries, RDS is a system for transmitting station
identication, a description of the station’s program type, indication of
national, regional or local programs and the correct time. RDS also allows
you to search for favorite program types.
The M4 is “XM Ready” which means that with the addition of separately sold
XM Mini-Tuner CPC-9000 and XM Mini-Tuner Home Dock, it has everything
you need to listen to live XM.
Until now, analogue radio signals such as FM or AM have been subject to
numerous kinds of interference on their way from the transmitter to your
radio. These problems were caused by mountains, high-rise buildings
and weather conditions. With DAB (Digital Audio Broadcast), you can now
receive CD-like quality radio programs without any annoying interference
and signal distortion.
