Introduction

Thank you for purchasing this Cambridge Audio Azur 651C CD player.
Like all Cambridge Audio products, the 651C adheres to our 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.
Our third generation S3 servo solution is featured which can dynamically
adjust the focusing, tracking and output level of the disc reading laser in
real-time. This ensures maximum retrieval of the digital information with
extremely low data jitter (timing variantions).
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.
Twin WM8742 24bit/192kHz-capable
Microelectronics coupled to our proprietary Double Virtual Earth Balanced
filter topology perform the critical Digital to Analog conversion. Special
Metal Electrode Face resistors, polypropylene caps and custom-made
electrolytic capacitors have all been used for their superior sound quality.
A toroidal transformer is fitted to provide lower noise and less waveform
distortion for quieter PSU operation.
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 this CD player. 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.
