Thank you for purchasing your Azur 651T. We are confident that you will
enjoy many years of listening pleasure from it. Like all Cambridge Audio
products, the Azur 651T adheres to our three core principles – stunning
performance, ease of use and incredible value.

The 651T supports both the digital DAB and analogue FM/AM radio
systems. For FM/AM the 651T features true analogue domain decoding of
FM/AM for best sound quality with this format.

For DAB broadcasts the built in digital radio tuner is compatible with both
the DAB and DAB+ (AAC+ format) standards and features a very high
quality WM8740 Digital to Analogue conver ter from Wolfson
Microelectronics.

An Azur Navigator remote is provided, giving full remote control of the
tuner functions and those of our amplifiers in an attractive and easy to
use handset.

The 651T 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 aerial is strongly recommended to get the best from
your 651T.

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

Cambridge Audio Technical Director

Ventilation

IMPORTANT - The unit will become hot when in use. Do not stack multiple

units on top of each other. Do not place in an enclosed area such as a
bookcase or in a cabinet without sufficient ventilation.

Ensure that small objects do not fall through any ventilation grille. If this
happens, switch off immediately, disconnect from the mains supply and
contact your dealer for advice.

Positioning

Choose the installation location carefully. Avoid placing it in direct sunlight
or close to a source of heat. No naked flame sources, such as lighted
candles, should be placed on the unit. Also avoid locations subject to
vibration and excessive dust, cold or moisture. The unit can be used in a
moderate climate.

This unit must be installed on a sturdy, level surface. Do not place in a
sealed area such as a bookcase or in a cabinet. Do not place the unit on
an unstable surface or shelf. The unit may fall, causing serious injury to a
child or adult as well as serious damage to the product. Do not place other
equipment on top of the unit.

Due to stray magnetic fields turntables or CRT TVs should not be located
nearby due to possible interference.

Electronic audio components have a running in period of around a week
(if used several hours per day). This will allow the new components to
settle down, the sonic properties will improve over this time.

Power sources

The unit should be operated only from the type of power source indicated
on the marking label. If you are not sure of the type of power-supply to your
home, consult your product dealer or local power company.

This unit can be left in Standby mode when not in use and will draw <1Win
this state. To turn the unit off, switch off at the rear panel. If you do not
intend to use this unit for a long period of time, unplug it from the mains
socket.

Overloading

Do not overload wall outlets or extension cord as this can result in a risk
of fire or electric shock. Overloaded AC outlets, extension cords, frayed
power cords, damaged or cracked wire insulation, and broken plugs are
dangerous. They may result in a shock or fire hazard.

Be sure to insert each power cord securely. To prevent hum and noise, do
not bundle the interconnect leads with the power cord or speaker leads.

Cleaning

To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any
cleaning fluids containing alcohol, ammonia or abrasives. Do not spray an
aerosol at or near the unit.

Battery disposal

Please dispose of any discharged batteries according to local
environmental/electronic waste disposal guidelines.

shock could result if this precautionary measure is ignored. In the event
of a problem or failure, please contact your dealer.

Plug Fitting Instructions (UK Only)

The cord supplied with this appliance is factory fitted with a 13 amp mains plug
fitted with a 3 amp fuse inside. If it is necessary to change the fuse, it is important
that a 3 amp one is used. If the plug needs to be changed because it is not suitable
for your socket, or becomes damaged, it should be cut off and an appropriate plug
fitted following the wiring instructions below. The plug must then be disposed of
safely, as insertion into a 13 amp socket is likely to cause an electrical hazard.
Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires
should be fitted as shown in this diagram. The colours of the wires in the mains
lead of this appliance may not correspond with the coloured markings identifying
the terminals in your plug. Connect them as follows:

The wire which is coloured BLUE must be
connected to the terminal which is marked
with the letter ‘N’ or coloured BLACK.

The wire which is coloured BROWN must be
connected to the terminal which is marked
with the letter ‘L’ or coloured RED.

The wire which is coloured GREEN/YELLOW
must be connected to the terminal which is
marked with the letter ‘E’ or coloured GREEN.

If a 13 amp (BS 1363) plug is used, a 3 amp fuse must be fitted, or if any other
type of plug is used a 3 amp or 5 amp fuse must be fitted, either in the plug or
adaptor, or on the distribution board.
