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 rst 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 tted 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.

8. Do not install near any heat sources such as radiators, heat registers,
stoves, or other apparatus (including other amplifiers) that produce
heat.
9. Do not defeat the safety purpose of the polarized or grounding-type
plug. A polarized plug has two blades with one wider than the other.
A grounding-type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched, particularly
at plugs, convenience receptacles and the point where they exit from
the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use with only the cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the apparatus.
When a cart is used, use caution when moving the cart/
apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for
