Do not use this unit near water; for example, near a bath tub, washbowl, kitchen sink, laundry tub, in a wet basement or near a swimming pool. The unit should be installed so that its location or position does not interfere with its proper ventilation. For example, it should not be situated on a bed, sofa, rug or similar surface that may block the ventilation openings; or placed in a built-in installation, such as a bookcase or cabinet, that may impede the flow of air through its ventilation openings. If an outside antenna is connected to your tuner or tuner-preamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 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 lead-in 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.

REPLACEMENT WITH UNAUTHORIZED PARTS MAY RESULT IN FIRE, ELECTRIC SHOCK OR OTHER HAZARDS. NAD

NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installer’s attention to Article 820-22 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.

CLASS 1 LASER PRODUCT

Install the Compact Disc player on a level, vibration-free surface. (Severe vibration, or operation in a tilted position, may cause the player to mis-track.) The player may be stacked with other stereo components, as long as there is adequate ventilation around it. If the player is placed in close proximity to a radio tuner (AM or FM), a VCR, or a television set, the operation of its digital circuits may produce static that would interfere with reception of weak broadcast signals. If this occurs, move the CD player away from other devices or switch it off when viewing or listening to broadcasts.

Connect this power cord to an AC mains wall outlet or to an AC convenience outlet at the rear of your amplifier. FRONT PANEL CONTROLS (fig.2)

Press this green button to switch on the power to the disc player. Press again and release to switch the power off.

1. Connect a stereo cable from the L (left) and R

(right) Line Output jacks to the corresponding CD inputs on your amplifier.

2. Plug in the AC power cord.

3. Press the green POWER button to turn on the

4. Press OPEN to open the disc drawer.

5. Place a CD, label side up, in the tray’s circular

recess. Be certain that the disc is centered within the recess. To play a disc, press the OPEN button to open the disc drawer. Place the CD within the large circular recess in the drawer, with its transparent playing surface facing down. The label must face UP. CD-3 discs (3-inch CD ‘singles’) can be played without the aid of an adapter. Place the disc in the drawer, centered in the smaller circular recess, with its label facing UP.

6. Press PLAY/PAUSE. The drawer closes automatically, and the disc begins to play.

NOTE: This player was not designed to accommodate a ‘damping disc’ placed on a CD, nor two CDs stacked together. It plays audio CDs, but not discs identified as CD-V, DVD, CD-I, CD-ROM, or PHOTO CD.

7. At any time you may press SKIP

select different tracks on the disc.

8. Press PLAY/PAUSE if you want to stop play

temporarily while keeping the pickup at its current position on the disc. Press PLAY/PAUSE again when you want to resume playback. Press STOP if you want to end play and re-set the pickup to the beginning of the disc. REAR PANEL CONNECTIONS (fig.1)

Connect a cable from these jacks to your amplifier. Plug one end of a stereo audio cable into the L (upper) and R (lower) output jacks. Connect the other end of the cable to your stereo amplifier’s CD input, or to any other ‘line-level’ input jacks (such as the AUXiliary inputs). Do NOT connect this cable to the amplifier’s PHONO input jacks.

The digital playback signal is available at this output jack. The serial data output is taken after the error correction but before the digital-to-analogue conversion and filtering. The output is transformer-isolated from the built-in D-to-A circuits. It may be connected to any digital signal processor that conforms to the Sony/Philips (SPDIF) standard. To use the digital output, connect a cable from this NAD

jack to the “CD Digital” or equivalent input on a digital processor. For best results, the cable should be a 75 ohm coaxial cable of the type used for video signals, with an RCA phono plug at each end. (To distinguish them from similar phono-plug cables used for analogue audio signals, video and digital signal cables often are colour-coded with yellow plugs.) The display provides information about playback status and about the laser pickup’s location on the disc. The displayed track/time information is obtained by reading inaudible ‘sub-codes’ in the disc. TRACK NUMBER. Each disc is segmented into numbered tracks when the recording is made; typically each numbered track will correspond to a different song, symphonic movement, etc. These track numbers are identified on the CD package and are encoded in the disc by its manufacturer. In some CDs, at the manufacturer’s option, tracks may be sub-divided into sections identified by Index numbers. This player does not display Index numbers. TIME. Normally this display shows the time elapsed since the beginning of the current track. Using the TIME button you can switch the display to show the playing time remaining to the end of the disc. When you load a different disc and use the OPEN button to close the disc drawer, the display shows the number of tracks and the total playing time of all the tracks on the disc. STATUS. A right-pointing arrowhead , located near the left edge of the time display, glows during

PLAY. Two vertical bars indicate that the player is in PAUSE. In STOP mode the display reverts to showing the number of tracks and total playing time of the disc. ‘no diSC’ glows in the display when no disc is present or when you load a disc that cannot be read (because it is dirty or is upside-down). REPEAT ONE glows in the upper-left corner during repeat-play of a single track. REPEAT ALL glows during repeat-play of the entire program or disc REMAIN glows in the top centre area of the display if you have pressed the TIME button to show the remaining time in the disc. RANDOM. When the C520 is in Random mode “RANDOM” will be shown in the Display Panel. CALENDAR DISPLAY TRACK LISTING. Displays a list of tracks available on the disc. As each track is played its number is blanked out on the Track Listing, giving a simple indication of how much of the disc has been played and how much remains. The display shows up to 16 numbered tracks. REMOTE RECEIVER. An infrared sensor, located at the right-hand portion of the display window, receives commands from the remote control. There must be a clear line-of-sight path from the remote control to this window; if that path is obstructed, the remote control may not work.

Press this button to open the disc drawer, and press it again to close the drawer. If this button is pressed while a disc is being played, the playback will stop, the pickup will re-set to the beginning of the disc, and the drawer will open. When the disc drawer is open, the drawer-closing mechanism can also be activated by pressing PLAY or by gently pushing the drawer inward. CAUTION: The disc drawer is opened and closed by an internal motor. Do not close the drawer by hand with the power off. When the drawer closes, the player scans the disc’s ‘table of contents’ and displays the number of tracks and total playing time on the disc. If you press PLAY to close the drawer this display is skipped, and play commences immediately at Track 1.

This dual-function button alternates between starting and stopping playback. Press to start play or to resume play after Pause. During play, press this button to stop playback temporarily, keeping the laser at its current position on the disc. The PLAY mode is identified by a right-pointing arrowhead in the display. The PAUSE mode is identified by two vertical bars To resume playback at the exact point where it stopped, press PLAY/PAUSE again. If you don’t want to resume play at the same point, you may use the SKIP and SCAN controls to cue the pickup to a different starting point before pressing PLAY again.

The TIME button has two modes, as follows: TIME: the elapsed time since the beginning of the current track, in minutes and seconds. (This is the ‘default’ setting, selected automatically when the player is turned on.) REMAIN: the total playing time that remains until the end of the disc and the total number of remaining tracks (including the current track).

This button stops play, cancels any repeat-play cycle, and re-sets the pickup to the beginning of the disc. The display reverts to showing the number of tracks and total playing time on the disc.

This button engages an endless-repeat cycle. Press the Repeat button once to select the REPEAT ONE mode, in which only the current track is repeated over and over again. Pressing the Repeat button once again selects the REPEAT ALL mode, in which the entire disc is played from beginning to end, over and over again. Press the Repeat button a third time to cancel the repeat cycle and return to normal operation.

Pressing RANDOM will play all the tracks on the CD in a random order. Press RANDOM either from the Stop or the Play mode and the C520 will play the tracks on the CD in random order until all the tracks have been played. Press RANDOM button again to cancel Random play and return the C520 to the normal Play mode. When the C520 is in Random mode ‘RANDOM’ will be shown in the Display Panel.

SCAN BACK The SCAN button causes the optical pickup to scan backward through the recording at high speed. This button works only while the player is in PLAY or PAUSE. After a STOP command, or after loading a new disc, you must press PLAY before the scan circuit will work. If the scan is initiated while the player is in PAUSE the scan is silent, approximately 15-20 times faster than playing speed. If the scan is initiated during PLAY it is much slower (approximately three times playing speed), and the music will be heard in fragmentary form at reduced volume as the player scans through it. Use this ‘audible scan’ to cue the player precisely to the spot where you want to resume play. If you scan back to the beginning of the disc while playing Track 1, the player automatically reverts to normal playback. SCAN FORWARD The SCAN button causes the optical pickup to scan rapidly forward through the music. The behavior NAD

of this function is similar to SCAN

If you scan forward to the end of the disc while playing the final track, the scan will stop and the Time display will show the table of contents. (There is no ‘wrap-around’ mode.)

SKIP BACK The SKIP button causes the laser to jump backward to the beginning of each numbered track on the disc. The first press skips back to the beginning of the current track. Press SKIP twice to skip back to the previous track. Continuous pressure will cause the player to skip tracks repeatedly, concluding at the beginning of the disc (Track 1). Pressing SKIP once during play causes the pickup to jump back to the beginning of the current track and play it again. To access the previous track while in Play Mode you must tap SKIP twice in rapid succession, once to reach the beginning of the current track and again to jump to the previous track. SKIP FORWARD During play, pressing SKIP will jump the laser to the beginning of the next track and resume play there. Thus, to sample each song on a disc, press PLAY and then tap SKIP after you’ve heard a few seconds of each track. REMOTE CONTROL A wireless remote control is provided with your compact disc player, enabling you to operate playback functions from the comfort of your chair or from virtually anywhere in the room. For reliable operation there should be a clear lineof-sight path from the remote control to the front of the CD player. If the player does not respond to remote commands, it may be that this line-of-sight path is obstructed by clothing, paper, or furnishings. Numeric keypad. Most of the buttons on the remote control handset have the same effect as the corresponding buttons on the front panel of the disc player. In addition the handset is equipped with a direct-entry numeric keypad, which causes the player to jump directly to the beginning of a numbered track and commence play. Thus to play Track 5, simply press 5. To play Track 23 press +10, +10, 3. NAD

and press gently until it latches. In some cases, poor operation may be caused by corrosion or fingerprint oil on the battery contacts. Remove both cells, rub the metal contacts at both ends of each cell with a clean cloth or a pencil eraser, and re-install the cells, being careful to orient them correctly. MAINTENANCE At periodic intervals, open the disc drawer and wipe with a damp cloth to remove any loose dust.

HANDLING COMPACT DISCS

Handle Compact Discs with care. The playback of a disc will not be impaired by small dust particles, a few light fingerprints, or slight scratches. But large scratches, or a thick layer of oily fingerprints, can prevent the player from tracking the disc. (Incidentally, although the tracking laser ‘plays’ the disc through its clear side, the actual data surface is embedded directly beneath the label, protected only by a very thin coating of lacquer. So a scratch that cuts through the label may damage the disc more than a similar scratch on the transparent ‘playing’ surface. Thus you should treat both surfaces of the disc with care.) Severe scratches or fingerprints may cause the player to mis-track (skipping ahead, or repeating the same passage). Less severe damage may produce very brief bursts of high-frequency noise. The tracking and error-correction circuits of this NAD CD player are unusually sophisticated, providing secure tracking of flawed discs that are unplayable on some other players. Nevertheless, the discs should not be abused or handled carelessly. For best results, grasp the disc only by its edges. Another safe method is to put a finger in the center hole, using the thumb at the edge to hold the disc steady. Each disc should be kept in its protective storage case when not in use. To open the standard Philipstype plastic CD case, grasp the top and bottom of the case with the fingers and thumb of the left hand; then grasp the left and right edges of the case with the fingers and thumb of the right hand, and pull the case open with the right thumb.

INSTALLING AND REPLACING BATTERIES

The disc is held in place within the case by an expansion hub in its center hole. To remove the disc, press the hub with a finger to release the disc, then lift it out by gripping its edges between the fingers and thumb. To replace the disc in the case, simply align its center hole with the hub and press the disc onto the hub. The remote control requires two 1.5-volt AAA-size (i.e. UM-4 or IEC RO3) cells. Alkaline cells are recommended, to obtain maximum operating life. CLEANING DISCS To open the battery compartment, place your fingertip in the recess on the rear of the remote control , push against the flexible edge of the battery cover and lift the cover upwards. Install fresh cells, orienting them as shown on the diagram within the compartment. The coil springs should contact the (-) end of each cell. Push the battery compartment cover back Soiled discs may be cleaned by wiping with a soft cloth, either dry or moistened with water. Do NOT use conventional LP record-cleaning products (cleaning solutions, sprays, treated cloths, or anti-static preparations), nor any kind of chemical solvent (alcohol, benzene, et al). A severely soiled disc may be washed in a warm-water spray, possibly with a small

amount of a mild kitchen detergent added, and then wiped dry with a clean, soft towel. When cleaning the disc, use only RADIAL strokes (from center to edge). Never use a circular wiping motion like that used for cleaning ordinary LP records, because in wiping the disc there is a risk of scratching it. A radial scratch will do the least harm because it affects only a small portion of each circular data track, which can be fully compensated by the player’s error-correction circuits. But a circular scratch that follows a data track may damage such a long continuous segment of data that it cannot be corrected. bits, while photo-diodes detect the reflected illumination from the disc and convert it into an electronic signal which is then decoded to recover the musical waveform in each stereo channel. You cannot see the laser operating, because it operates at wavelength of 7800 Angstroms, which is in the infrared and thus invisible to the human eye. The Compact Disc player is completely safe for children to use. The laser operates at very low power and is concealed within the player mechanism. Even when the player is disassembled, the laser remains sealed within an optical system that causes its light to focus only 1 millimeter from the lens and then diverge rapidly, reducing its intensity to negligible levels.

The Compact Disc player uses a solid-state semiconductor diode laser, mounted on a tracking servo mechanism, to play the disc. The laser illuminates the track of microscopic pits representing the digital data TROUBLESHOOTING SYMPTOM POSSIBLE CAUSE No Power when the POWER button is set to ON Poor or no power plug connection at the AC outlet. Insert the power plug firmly into the AC outlet. Disc play does not start The disc is loaded upside down. Reload the disc with the label side UP. The disc is too dirty. Clean the disc. No sound Incorrect audio cable connections. Connect the CD player to the amplifier/receiver correctly. Incorrect amplifier/receiver operation. Make sure that the input selector on your amplifier or receiver is set to CD. Sound skips The CD player is subject to vibration or physical shock from external sources.
