Thank you for purchasing this Cambridge Audio Azur 550C or 650C CD

player. Like all Cambridge Audio products, the 550C and 650C adhere

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.

We have developed a completely new S3 servo for these models. The S3

is our third generation proprietary audiophile servo solution and draws

on all our experience with this technology. It utilises the latest double-

sided surface-mount technology for ultra short signal paths with freedom

from wire links. It can dynamically adjust the focusing, tracking and

output level of the laser in real-time, allowing for maximum retrieval of

the digital information with extremely low data 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 to enhance those discs that feature it.

For the critical Digital to Analogue converter stages, we have also moved

to double-sided surface-mount to remove wire links and shorten all signal

paths. New Metal Electrode Face resistors, polypropylene caps and

custom-made electrolytic capacitors have all been used for their superior

sound quality.

Both models employ the WM8740 24bit/192kHz-capable Digital to

Analog converter from Wolfson Microelectronics. This very high quality

part is coupled to our proprietary Double Virtual Earth Balanced ﬁlter

topology which has been revised and re-calibrated for Bessel coefﬁcients

in both the 550C and 650C. In line with all our models, a toroidal

transformer is ﬁtted to provide lower noise and less waveform distortion

for quieter PSU operation.

The 650C differs from the 550C in using a pair of WM8740 24bit/

192kHz-capable Digital to Analogue converters implemented in a dual

differential conﬁguration. Since each channel has its own DAC to process

information, completely separate and symmetrical analogue ﬁlter circuitry

can be implemented.

The 550C features a Three-Pole Double Virtual Earth Balanced ﬁlter

topology with new Bessel co-efﬁcients. The 650C features an even more

sophisticated Four-Pole Dual Differential Double Virtual Earth Balanced

version of this ﬁlter. This means that the DAC for each channel features

two fully balanced outputs, each of which are then summed in a third

order virtual earth balanced ﬁlter stage. A further ﬁrst order balanced

ﬁlter stage sums the balanced outputs of the earlier ﬁlter stages. This

double-balanced conﬁguration largely rejects noise and distortion

products present in the DACs and ﬁlters themselves to produce an

unprecedented level of performance.

These models are amongst the ﬁrst to feature a new casework design

with a thicker braced front panel, more rigid wrap-over lid assembly and

dual-layer damped feet, all of which contribute to better 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.
