THANK YOU FOR CHOOSING NAD.
The C 427 AM/FM Tuner is a technologically advanced and highly capable
product — yet we have invested great effort in making it simple and
easy to use. We have been careful to ensure that the C 427 is as musically
transparent 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. As with all our products,
NAD’s “Music First” design philosophy guided the C 427’s design, such that
it can confidently 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 C 427.
One more thing: We urge you to register your C 427 ownership on the NAD

ESPAÑOL
SAVE THE PACKAGING
Please save the box and all of the packaging in which your C 427 arrived.
Should you move or otherwise need to transport your C 427, 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
PORTUGUÊS
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 23 feet/7
meters, between the C 427’s front panel and your primary listening/viewing
position—this will ensure reliable infrared remote control communications.
Avoid placing the unit in direct sunlight or near sources of heat and damp.
It is perfectly possible to stack the C 427 on top of other components.

NEDERLANDS
AM ANTENNA TERMINAL
• The AM loop antenna supplied with the C 427 (or a suitable
replacement) is required for AM reception. Open the clip terminal
lever; insert the wire making sure to match the color-coded (white
and black) ends of the wire to that of the terminal and close the
lever ensuring that the lever locks the wire in place.
• Testing different positions for the antenna may improve reception;
vertical orientation will usually produce the best results. Antenna
proximity to large metal objects (appliances, radiators) may impair
reception, as will attempts to lengthen the wire to the loop.
• If an external AM antenna is used, make connections to the AM
and GND terminals in accordance with the instructions supplied
with the antenna. Refer also to the item about ASSEMBLING THE
LOOP ANTENNA at the LISTENING TO AM/FM RADIO section of the
OPERATION page.
5 +12V TRIGGER IN
• This input allows the C 427 to be switched remotely to standby
mode and ON by ancillary equipment, such as an amplifier, preamp,

DIRECT RECALL OF A PRESET
You can directly recall a desired Preset number.

ABOUT RDS
The Radio Data System (RDS) permits sending small amounts of digital
information using conventional FM radio broadcasts. The C 427 supports
two RDS modes, program-service name (PS mode) and radio-text (RT
mode). Not every FM station incorporates RDS in its broadcast signal. In
most areas you will find from one to several RDS-enabled stations, but it is
by no means impossible that your favorite stations will not be broadcasting
RDS data.
ITALIANO
When an RDS-enabled FM broadcast is tuned, the VFD will show its
program-service name (PS) text and the station’s radio-text (RT) readout,
if any, which might scroll song- or artist-name, or any other text of the
station’s choosing.
PORTUGUÊS
The C 427 offers very high quality sound from radio broadcasts. The
reception and sound quality will always be dependent to a degree however
on the type of antenna(s) used as well as proximity to the broadcast origin,
geography and weather conditions.
