TESTING PROCEDURE (1) Load the test disc (Sony Test CD YEDS-7) and set the unit into PLAY mode. (2) Connect the scope to R227 (Pin 15 of U101) and DGND (J144). Scope setting: Coupling : AC. Vertical sensitivity : 0.2 V/ div. Horizontal time base : 0.5 S/div. (3) Observe the waveform is 2.0V p-p +/-5% and the eye pattern is at its best shape (see FIG. 1).

IMPORTANT NOTES

INSTRUCTION FOR HANDLING OPTICAL SYSTEM BLOCK PICK-UP
Electrostatic breakdown of the laser diode in the optical system block may occur due to a potential difference caused by electrostatic charge accumulated on clothing, human body, etc. A ground must be provided as follows to prevent any electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a ground band (1M ohm) that is properly to remove any static electricity that may be charged on the body. 2. Ground for Work Bench Be sure to place a conductive sheet (1M ohm) or copper plate with proper grounding on the work bench or other surface on which the pick-up is to be placed. 3. Because the static electricity charge on the clothing does not discharge through the body grounding band, do not let clothing to get in contact with the pick-up unit.

INCORRECT

CORRECT

1.Grounding band 1M ohm

1M ohm 2.Conductive Sheet or Copper Plate
NOTE: Laser diodes are so susceptible to damage from static electricity that even if a static discharge does not ruin the diode, it can shorten its life or cause it to work improperly.
PRECAUTIONS FOR CHECKING BEAM EMISSION
The laser beam of this unit is focused on the reflecting surface of the objective lens in the optical system block. Therefore, keep your eyes at least 12 inches (30 cm) away from the objective lens when the laser diode is ON. (Operation Check Method for Laser Diode and Focus Search Function.) When the POWER switch is turned ON after the chucking plate is removed, observe the objective lens and confirm that the following operations are performed properly. (The optical system should be at the lead-in area position when it is checked at this time.) (1) The laser should be at the innermost position after the chucking plate is removed. (2) The diffused light of the laser beam can be seen when the POWER switch is turned ON. (3) Vertical (up and down) movement of the objective lens (2 or 3 times) will take place.

PRECAUTIONS WHEN CHANGING LASER PICK-UP
When removing the pick-up assembly, short circuit the PCB tracks on the optical block as show in the drawing in order to protect the pick-up before removal. NOTE: Replacement pick-up assemblies are supplied with the PCB pattern already protected. DO NOT REMOVE THE SHORT CIRCUITS UNTIL YOU HAVE FINISHED FITTING THE PICK-UP.

Protective soldering place for laser diode Caution: Laser diodes are extremely susceptible to damage from static electricity. Even if a static discharge does not ruin the diode, it can shorten its life or cause it to work improperly. When replacing the pick-up, use a conductive mat, a grounded soldering iron, and so on, to protect the laser diode from static damage. Ground Conductive Wrist Band for Body
Soldering Iron with Ground wire
Ground Line Less than 10 ohm
Conductive Gum Mat - 11 -

quickly accessed using the SKIP function (Forward and Back), and the SCAN function (Forward and Back) gives an aural prcis of individual tracks, giving the listener the opportunity to reach specific sections of the track. The Vacuum Fluorescent display provides clear and understated, yet comprehensive information to the listener. The track number is displayed, and for those who regularly transfer CDs to cassette, MiniDisc or CD-R, the button displays the current time elapsed or remaining for complete CDs or individual tracks. A calendar type section in the display gives immediate visual information of how many tracks in total there are on the CD. Not all digital outputs are equal. In the case of the NAD C542, careful attention has been paid so that best use can be made of the ever increasing number of products now available with digital inputs (CD, MD recorders, computer sound cards, outboard D to A converters, etc.). Unusually at this price point, the coaxial output is buffered and isolated by a transformer from the converter itself and the output impedance has been carefully tailored to produce a precise 75 ohms impedance to ensure perfect matching. This attention to detail reduces the timing errors (jitter) that could otherwise distort the digital data stream. An optical Toslink output is also provided allowing connection to devices that only provide this option. The Model C542 comes supplied with the new NAD CD6 full function remote control, offering all of the features described above from the comfort of your listening chair. On top of that, the remote control handset gives you direct track access and programming facilities, as well, saving the users time when theyre storing preferred song titles. Up to 20 tracks can be programmed. It is possible to delete tracks without using the program function by simply using the delete key. Separate power regulators for the digital and analog sections isolate the two electrically, reducing interference effects. Furthermore, careful layout of the PCB tracks around the Digital-to-Analogue converter helps to contain RF radiation and interference.

The C542 replaces NADs venerable C541i. With the worldwide acclaim and numerous awards for outstanding performance and value, it is fair to ask why NAD would mess with success. But NAD has never rested on its laurels; rather development is ongoing at the NAD Lab and new models are launched when we feel a significant improvement has been achieved. Such is the case with the C542. Besides the new more refined cosmetics and improved remote control, many component changes have been implemented in the C542s circuits. The cumulative effect of these changes is quite dramatic, improving low frequency slam and extension, while maintaining the pace and timing for which the C541i was so lavishly praised. Image depth and scale are further enhanced while retaining the timbral accuracy and lucid harmonic structure of its predecessor. Features and Circuitry Creating ones own favorite compilation CD-R and CD-RWs on a CD Recorder is becoming ever more popular, and unlike ordinary CD players, the C542 will easily play these discs. We have included a number of additional features to make your listening more enjoyable: RANDOM gives the listener a random selection of all tracks on the disc in play, and REPEAT allows repeat playing of either the entire disc, or individual tracks. Individual tracks can be

filter was chosen for its excellent low-level linearity and detail retrieving capabilities. Metal film resistors and polypropylene capacitors are used in key areas to ensure a highly accurate frequency response. High quality Burr Brown 2134 professional grade op-amps are used instead of the much lower grade and type normally found at this price level. Apart from the single output capacitor, no other capacitors are used in the signal path. The output impedance is very low at 300 ohms, making the NAD C542 less sensitive to cables or the ancillary equipment it is partnered with.
We urge you to listen to the NAD C542 with a wide range of program material and with the best ancillary equipment to fully appreciate the refinement of this modest looking and by High end standards inexpensive CD player. You can spend a lot more money for a CD player, but we think youll have a difficult task finding a more musically complete and rewarding performance than that offered by the NAD C542. A new benchmark has been set.
