Thank you for purchasing this Cambridge Audio Azur 550A or 650A

ampliﬁer. We are conﬁdent that you will enjoy many years of listening

pleasure from it.

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. Speciﬁcally, these models use

new output transistors, a new high-quality Alps volume pot, new

polypropylene signal capacitors, gold-plated speaker outputs, custom-

made electrolytic capacitors in critical positions and several new circuit

tweaks.

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 resonance

control.

A new version of our proprietary CAP5 system has been developed to

allow a greater dynamic envelope to the protection scheme, offering a

more dynamic real-life performance. Also featured is an environmentally

friendly low power (<1W) standby circuit. This circuit completely powers

down the ampliﬁer circuits in Standby mode yet is itself totally isolated

when the ampliﬁer is on, thus having no effect on sound quality.

Both the 550A and 650A have fully buffered input circuits for low

crosstalk and improved stereo imaging, driving a completely discrete

bipolar transistor-based ampliﬁer and all powered from a custom

audiophile-grade toroidal transformer. A new MP3/Portable Media Player

input has been ﬁtted to the front panel for convenience, and the supplied

remote can control the ampliﬁer, any of our matching CD players and

basic iPod functionality.

The 650A differs from the 550A by having separate transformer

secondaries for left and right channels, twin rectiﬁers and separate PSUs

for dual-mono operation of the left and right power ampliﬁers. An even

larger heatsink and transformer are also employed which allows for a

greater power output of 75wpc (compared to 60wpc for the 550A).

Your ampliﬁer can only be as good as the system it is connected to. Please

do not compromise on your source equipment, speakers or cabling.

Naturally, we particularly recommend models from the Cambridge Audio

Azur range, which have been designed to the same exacting standards as

our ampliﬁers. 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.
