NAD 5220 CD player

NAD's Compact Disc players are known for fine sound, superior tracking, powerful error correction, and reliable construction. But the greatest differecnce between NAD players and other is NAD's uniquely simple and logical approach to design.

The NAD 5220  CD player is securely in this no-frills, high-performance, best buy tradition. They were created for people whose primary interesst is music, not gadgets. The theme of simplicity extends to their analog output circuits as well; with only a handful of electronic components in the signal path, their sound is particularly pure and clean.

This player is eqquipped withh full-disc automatic repeat and programmable memory playback of up to sixteen selections in any order. And both players include new features of significant value to users. The economical NAD 5220 adds a Timer Pay feature that autimatically plays a disc when the power is switched on. So, by plugging the player's AC power cord  into a clock timer, you can provide your own choice of wake up music in the morning instead of depending on a clock radio.

NAD 5220 employ a solid metal chassis for maximum stability, precise alignment, and long-term reliability. The metal chassis provides electrical shielding to reduce leakage of interference from the digital circuits into your phono preamp or FM tuner. The playback mechanism floats on springs within, minimizing the transmission of vibration to the spinning disc, ensuring secure tracking even in the presence of the powerful vibrations produced by your loudspeakers.

The output circuit in this player exemplifies the "less is better" approach, with only a handful of electronic components in the signal path. The elegantly simple analog stage has only one active circuit in each channel; a high-speed filter that provides de-emphasis and removes unwanted ultrasonic noise. To ensure that this active filter circuit cannot be overdriven into transient distortion, the analog signal is pre-smoothed by a passive multipole filter that is connected directly to the digital de-multi-plexer. High-quality polypropylene capacitors are used at sonically critical points in the circuit, e.g., in the treble de-emphasis network.
