Introduction

Thank you for purchasing this Cambridge Audio Azur 351C CD player.
Like all Cambridge Audio products, the 351C adheres to three core
principles - stunning performance, ease of use and incredible value.
Developed as part of our on-going research and development regime,
including extensive listening tests, we have incorporated many subtle
tweaks and improvements to our circuits, components and layouts in the
pursuit of our passion for sound quality.
The 351C features our S3 Servo, our third generation of proprietary
audiophile servo solution which can dynamically adjust the focusing,
tracking and output level of the laser in real-time. This allows for
maximum retrieval of the digital information with extremely low jitter.
This is complemented by our use of a highly accurate master clock
oscillator and very carefully designed impedance-matched clock
buffering schemes. We have also incorporated support for CD-text for
those discs that feature it.
For the critical Digital to Analogue converter stage, a WM8728 Digital to
Analog converter from Wolfson Microelectronics is featured on a double-
sided surface-mount PCB to remove wire links and shorten all signal
paths. Polypropylene caps and custom-made electrolytic capacitors have
been used for their superior sound quality.
A toroidal transformer is fitted to provide lower noise and less waveform
distortion for quieter PSU operation and improved regulation.
The 351C also incorporates a rigid casework design for control of
resonance. Another highlight is an eco-friendly low power (<1W) standby
circuit. This circuit completely powers down the CD player circuits in
Standby mode yet is itself totally isolated when the CD player is on, thus
having no effect on sound quality.
Your CD player can only be as good as the system it is connected to.
Please do not compromise on your amplifier, speakers or cabling.
Naturally, we particularly recommend amplification from the Cambridge
Audio Azur range, which has been designed to the same exacting
standards as our CD players. Your dealer can also supply excellent
quality Cambridge Audio interconnects to ensure your system realises
its full potential.
Thank you for taking the time to read this manual; we recommend you
keep it for future reference.
