If an indoor antenna is used (either built into the set or installed separately), never allow any part of the antenna to touch the metal parts of other electrical appliances such as a lamp, TV set etc. ATTENTION CAUTION CAUTION POWER LINES Any outdoor antenna must be located away from all power lines. OUTDOOR ANTENNA GROUNDING If an outside antenna is connected to your tuner or tunerpreamplifier, be sure the antenna 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 No. 70-1984, provides information with respect 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. a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze wire, or larger, as a ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 - 1.83 m) apart. c. Mount antenna discharge unit as close as possible to where leadin enters house. d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. see NEC Section 810-21 (j). EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 - RADIO AND TELEVISION EQUIPMENT. NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installer's attention to Article 820-40 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the ground cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

REPLACEMENT WITH UNAUTHORIZED PARTS MAY RESULT IN FIRE, ELECTRIC SHOCK OR OTHER HAZARDS. 2 REAR PANEL CONNECTIONS FRONT PANEL CONTROLS 3 NAD C420 Stereo AM/FM Tuner 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 or to select a station. 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". 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 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 12Vtrigger 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. GB FRONT PANEL CONTROLS 1. POWER ON/OFF POWER switches the tuner on or off. Pressing the Power switch turns the Tuner on, the Display Panel and Power Status Indicator (No. 2) will light up. Pressing the Power button again will switch the unit off. NOTES: The C420 has a receiver for remote control commands built-in. Most NAD system remote control handsets with an On/Off toggle button or separate On and Off button will be able to switch the tuner from On to Stand-by and vice-versa. The C420 uses a memory back-up system to store Preset information. This information is retained for several weeks, even if the unit is switched off completely or unplugged. When switching power On, the C420 will go back to the station last tuned to before the unit was turned off. This will allow you to make timer recordings using an external timer and recorder. 2. POWER STATUS INDICATOR The Power Status Indicator will light up green when Power is on. When the tuner is switched to Stand-by mode (through either a remote control or the 12V trigger input) the indicator will light up am ...
