NOTES ON INSTALLATION
Your NAD C420 should be placed on a firm, level surface. Avoid
placing the unit in direct sunlight, near sources of heat and damp
or in poorly ventilated positions. It comes with RCA leads for
connection to your amplifier. Ensure that leads and connectors are
not damaged in any way and all connectors are firmly pushed home.
If the unit is not going to be used for some time, disconnect the
plug from the AC socket. Should water get into your NAD C420,
shut off the power to the unit and remove the plug from the AC
socket. Have the unit inspected by a qualified service technician
before attempting to use it again. Do not remove the cover,
there are no user-serviceable parts inside.
Use a dry soft cloth to clean the unit. If necessary, lightly dampen
the cloth with soapy water. Do not use solutions containing benzol
or other volatile agents.
QUICK START
Use the RCA-to-RCA lead to connect the NAD C420 left & right
outputs to the Tuner Input of your amplifier.
1. Plug in the AC power cord.
2. Connect C420's output to amplifier.
3. Connect AM and FM antenna.
4. Press the POWER button (No. 1) to turn on the NAD C420.
5. Press the AM/FM button (No. 6) to select AM or FM reception.
6. Press Preset/Tune button so that "PRESET" isn't lit in display;
the tuner is now in Tune mode.
7. Use TUNE/PRESET
REAR PANEL CONNECTIONS
1. FM ANTENNA
A ribbon wire FM antenna is included and should be connected to
the FM connector at the rear of the unit using the supplied
"balun" adapter (see fig 1). The ribbon aerial should be mounted
on a vertical surface and placed so that it forms a "T".
GB
Experiment with placement of the antenna to find the position that
gives the best signal strength and lowest background noise. An
inadequate FM signal normally results in high levels of hiss,
especially in stereo, and interference from external electrical
sources. In areas of poor FM reception, the tuner section's
performance can be improved by using an externally mounted FM
antenna. A qualified aerial installer will be able to advise and fit a
recommended aerial for your reception conditions.
2. AM ANTENNA
An AM loop antenna is supplied with the NAD C420 and is required
for AM reception. To connect the AM antenna, first press the keys
on the Antenna terminals downwards. Insert the bare antenna wires
into the two terminal holes and push the connector keys upwards
again to secure the connection (see fig 2). Test various positions for
the antenna but always ensure the loop is placed vertically for best
reception. Placing the antenna close to large metal items such as
metal shelves or radiators may interfere with reception.
3. OUTPUT
Using twin RCA-to-RCA leads, connect to the left (white) and right
(red) audio outputs to the "Tuner" input or other line-level input
such as "Aux" input of your amplifier. Do not connect this cable
to the amplifier's "Phono" input.

4. NAD-LINK IN OUT
The NAD-Link connector is used to pass commands from other
units fitted with NAD-Link connectors. This allows centralised
control of a complete system, and also allows some of the basic
functions of other NAD components (such as a CD player or
cassette-deck) also equipped with NAD-Link to be controlled with
an NAD system remote control. To function with such other units,
connect the C420's NAD-Link Out to the NAD-Link In on the other
unit. NAD-Link connectors can be daisy-chained, IN to OUT, so
that a whole system can be controlled from the remote control
facilities of one unit.
NOTES: The NAD C420 has a built-in receiver for commands
from a remote control and doesn't need to rely on NAD Link to be
remotely operated. It is advisable not to connect NAD-Link if the
other units that have their own built-in remote control command
receiver and are positioned together, in direct view from the
remote control handset. If you are unsure, try operating the
products without NAD-Link first; If the unit responds to the remote
control command, it will not be necessary to connect NAD-Link.
Never loop the last unit back to the first NAD unit in the NAD-Link
chain. Unplug all units from the mains before connecting or
disconnecting NAD-Link.
5. 12V TRIGGER IN
This input allows the C420 to be switched remotely to Stand-by
and On by ancillary equipment such as an amplifier or preamp, AV
processor, etc. which are also equipped with a 12V trigger output.
For switching Stand-by/Power On of the C420 by an external
component, connect the12V-trigger input of the C420 to the
remote component's DC output jack. The plug required is a
standard 3.5mm Mini-Jack plug ("mono"): The tip is the live or
+ connection, the shaft of the input jack is the 12V-trigger - or
ground connection.
NOTES: The C420's 12V Trigger will work within a range of 6 to
15 V DC level and typically draws less than 10mA of current.
Check the specifications of the Trigger output terminal on the
remote component to ensure it is compatible with the C420's 12V-
trigger input. NAD components equipped with 12V output triggers
are fully compatible with the C420's 12V input trigger.
Before making any connections to any 12V trigger input or output,
make sure all components are disconnected from the AC mains.
Failure to observe the above may result in damage to the C420 or
any ancillary components attached to it. If in doubt over the
connections, installation and operation of the 12V trigger output
consult your NAD dealer.
6. AC LINE CORD
Plug the AC power cord into a live AC wall socket or to an AC
convenience outlet at the rear of your amplifier.
