NAD C542 Compact Disc Player -
Design Details

Creating one’s own favourite compilation CD-R and CD-RW’s on a CD Recorder is becoming ever more popular, and unlike ordinary CD players, the C 542 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 quickly accessed using the SKIP function (Forward and Back), and the SCAN function (Forward and Back) gives an aural précis 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 C 542, 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 TOS Link output is also provided allowing connection to devices that only provide this option.

The Model C 542 comes supplied with the new NAD CD-6 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 user’s time when they’re 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 analogue 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 24 bit high resolution Burr-Brown Sigma-Delta Digital-to-Analogue converter chip with built in Pacific Microsonics digital

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 150 ohms, making the NAD C 542 less sensitive to cables or the ancillary equipment it is partnered with.

We urge you to listen to the NAD C 542 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 you’ll have a difficult task finding a more musically complete and rewarding performance than that offered by the NAD C 542. A new benchmark has been set.
