Thank you for purchasing this Cambridge Audio Azur 550T. We’re confident
that you will enjoy many years of listening pleasure from it.

The 550T is a newly-developed FM/AM tuner to compliment complement
the Cambridge Audio Azur range and incorporates sophisticated Alarm
and Sleep timer functions that can turn on and off connected Cambridge
Audio amplifiers fitted with Control Bus inputs/outputs and select the
Tuner input for the Alarm function.

A specific version of the Azur Navigator remote is provided, giving full
remote control of the tuner functions in an attractive and easy to use
handset.

The 550T can only be as good as the system it’s is connected to. Please
do not compromise on your amplifier, speakers or cabling. Naturally we
particularly recommend models from the Cambridge Audio Azur range
which have been designed to the same exacting standards as this tuner.
Your dealer can also supply excellent quality Cambridge Audio
interconnects to ensure your system realises its full potential.

The use of an external FM/AM aerial is also strongly recommended to get
the best from your 550T.

Thank you for taking the time to read this manual; we recommend you
keep it for future reference.

Cambridge Audio Technical Director
and the 550T design team
