| NAD 517 5-cd multi player |
The NAD 517 combines the convenience of a five disc "carousel" with the kind of performance that has won widespread acclaim for single-disc NAD players. Careful, innovative electrical and mechanical design endow the NAD 517 with a degree of audiophile sound quality not associated with a CD changer. And, of course, the NAD 517 represents excellent value for money - just as one expects from NAD. The NAD 517 offers all the convenience of a CD changer and more : Its drawer-loading transport accomodates five CDs, making uninterrupted music available for as long as six hours. Whilst playing one disc the listener can open the drawer and replace two discs. Fast disc and track access are also notable NAD 517 features
Unlike many multi-disc designs the NAD 517's 32 random-access programming and automatic "Shuffle play" features can both operate across all loaded discs. Another useful feature of the NAD 517 is the edit function. Use of this feature means that abrupt ending on tapes recorded from CD's are a thing of the past. After having selected the total tape time available (side A + B) on the NAD 517 it will automatically decide how many tracks will fit on one side of the tape. The supplied remote control handset makes changing discs and / or tracks easy with its direct access numeric key-pad from the comfort of your listening chair.
Besides convenience, ease-of-use and keen pricing, NAD products are also renowned for their sound quality and the NAD 517 is no exception : Digital-to-Analogue conversion is handled by the now world-wide acclaimed Bit stream converter which, due to the way it works, is free of all the non-linearity errors which plague so many of the compact disc players equipped with Multi-Bit converters. NAD engineers realised that it is not just the Digital-to Analogue converter which has an impact on the sound quality. The digital and analogue power supply stages are separated from each other by means of individual regulators to prevent any contamination of the analogue audio signal from the digital section. The entire output stage is completely DC coupled - a feature to be found almost exclusively in expensive single disc players - and controlled by DC servo circuitry to prevent any DC offset on the output.
The low output impedance ensures perfect interfacing with other components and interconnecting cables [even long stretches of cable] without any adverse effects. High grade components, have been used throughout all circuits, normally only to be found in expensive single disc players. Furthermore, multi-stage filtering removes unwanted ultra-sonic by-products [which would otherwise cause interference with your amplifier and other components of your system] of the decoding process without affecting the critical audio band.
As usual with NAD products, future upgrading and flexibility is easy and straightforward. The NAD 517 boasts a coaxial digital output from which the digital data can directly be transferred to digital recording formats such as DAT, MD or DCC recorders. To maintain the integrity of the digital data stream and to isolate the Digital-to-Analogue converter from the outside world an isolating transformer between the converter and output has been used.
