Informative display with switchable track, time and repeat
Random play and Repeat modes for single track or entire CD
Background :
Over the years NAD has built up an enviable reputation for building fine cd players offering outstanding value for money - the NAD 510
will further enhance that reputation. As always, sonic performance is the first priority at NAD. By deleting the remote control
and many seldom used features, the NAD engineers could spend the money saved on design and engineering directly related to performance
Not surprisingly, as a direct result of this approach the sound quality belies the NAD 510's keen price. Behind the deceptive simple front
panel lies sophisticated circuitry
Design :
As with all NAD cd players, particular attention has been paid to keep the analogue path free from RF interference [which can otherwise severely contaminate the purity of the audio signal]. For a start, all circuitry not directly related to the sound itself [ transport, servo's, display drivers, etc. ] has been relegated to separate circuit boards. The audio section has its own dedicated PCB located directly behind the output socket, minimising the length of the signal path and physically keeping it removed from the other boards. Separate power regulators for the digital and analogue sections isolate the two electrically as well, and furthermore, careful lay-out of the PCB tracks around the Digital-to Analogue converter helps to contain any remaining RF.
For the NAD 510 the much acclaimed Bitstream Digital-to-Analogue single bit converter chip was chosen for its excellent low level linearity
The output impedance is very low at 110, making the NAD 510 less sensitive to cables or the ancillary equipment it is partnered with. Paired with a 5-pole filter in the analogue stage and using high grade components, the result is an unparalleled open, rich and detailed sound that is commonly only available from more expensive machines
The understated yet comprehensive display gives the listener all the vital information required to access and enjoy the selected music. The track number is displayed and for those who regularly transfer cds to cassette tape, 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 how many tracks in total there are on the cd.
RANDOM gives the listener a random selection of all tracks on the disc in play and REPEAT allows repeat playing of the disc or individual tracks. Individual tracks are easily accessed by SKIP [Forward and Back]. SCAN [Forward and Back] gives an aural precis of individual tracks, giving the listener the opportunity to reach specific sections of the track
