The process of setting up the 640R is first to make all the connections
to your speakers and source equipment and then set the unit up via its
On-Screen Display (OSD), as there are various settings and adjustments
that need to be made before the 640R can be used.
However before you actually decide which connections to make or
perform any adjustments
it is strongly advised that you read through the
‘640R setup’ section of this manual first, starting on page 14.
A lot of explanation is included that will help you to choose the right
connection types for both your sources and TV.
Thank you for purchasing this Cambridge Audio Azur range AV r
eceiver.
The 640R is designed for excellent multi-cchannel surround-ssound
performance without compromising on music reproduction.
As such, the seven 100W audiophile grade fully discrete amplifiers are
kept as separate as possible from the processing and input stages and
feature a large power supply with a low flux toroidal transformer. This
careful design of the amplifier stages ensure that the 640R can
reproduce the dynamics and scale required for modern movie
soundtracks whilst also being able to reproduce a genuinely musical
performance with either stereo or multi-channel music sources.
A full range of digital and analog inputs are fitted. Digital inputs allow for
the connection of suitably equipped DVD players, satellite/set-top boxes
and games consoles for decoding into stereo, stereo + sub or various
digital surround formats. The latest formats are supported including
Dolby Digital and DTS in 5.1, 6.1 or 7.1 variants. The 640R is also
capable of decoding encoded analog or digital stereo sources in Dolby
Pro Logic® II or IIx and DTS Neo:6, again in 5.1, 6.1 or 7.1 variants for a
convincing and effective surround experience from a matrix encoded
stereo source. Sophisticated post-processing of 5.1 or 6.1 digital
material is also possible with PLIIx or DTS Neo:6 to turn these formats
into 6.1 or 7.1.
Conventional analog stereo inputs allow the connection of audiophile
CD players and the like, and an Analog Stereo Direct mode ensures the
very best possible stereo reproduction for these.
The 640R also carries a 5.1 / 6.1 / 7.1 channel analog input. This
feature allows for the connection of a DVD Audio or SACD player
equipped with a 5.1 output and is compatible with future external
6.1/7.1 audio formats.
As well as the full complement of audio inputs, the 640R also performs
Composite, S-Video and Component Video input switching and
transcoding. The component video inputs and outputs are progressive
scan and HDTV compatible and the unit features full On-Screen Display
(OSD) on all analog video outputs. Transcoding allows composite video
and/or S-Video to be converted to Component video for a simpler
interface to the TV/Monitor.
In addition HDMI switching allows the very latest DVD players and Set-top
boxes to be routed through the 640R to the TV/Monitor allowing direct
digital transfer of high definition video for the very best picture quality.
Multi-Room compatibility is featured in the form of A-BUS
Ready
TM
/Incognito ReadyTMoutputs for either Cambridge Audio Incognito
keypads (and power supply) or other manufacturers products
compatible with the A-BUS standard. This allows a 2 or 3 zone multiroom system to be easily constructed, second and third zone video
outputs mean the remote rooms can even have video capability.
An RS232 port, IR Emitter In and Control Bus In/Out also make it easy
to integrate the 640R into a Custom Install situation.
All this proprietary engineering is housed within our low resonance,
acoustically damped chassis. An Azur Navigator remote control is also
provided, giving full remote control of your AV receiver in an attractive
and easy to use handset.
Remember your 640R can only be as good as the system it is connected
to. Please do not compromise on your source equipment, speaker
package or video and audio cabling. Naturally we particularly
recommend DVD/CD players or other source equipment from the
Cambridge Audio Azur range, which have been designed to the same
exacting standards as our receivers. Your dealer can also supply
excellent quality Cambridge Audio interconnects to ensure your system
realises its full potential.
Thanks for taking the time to read this manual, we do recommend you
keep it for future reference.

Plug Fitting Instructions (UK Only)
The cord supplied with this appliance is factory fitted with a UK mains plug fitted
with a 5 amp fuse inside. If it is necessary to change the fuse, it is important that
a 5 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 mains 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 your model does not have an earth wire,
then disregard this instruction.
If a standard 13 amp (BS 1363) plug is used, a 5 amp fuse must be fitted, or if any
other type of plug is used a 5 amp fuse must be fitted, either in the plug or adaptor,
or on the distribution board.

Important safety instructions
ENGLISH
Please take a moment to read these notes before installing your 640R,
as they will enable you to get the best performance and prolong the life
of the unit. We advise you follow all instructions, heed all warnings and
keep the instructions for future reference.
Ventilation
IMPORTANT - The unit will become hot when in use.
Please ensure there is ample ventilation (at least 10cm clearance all
round). Do not put any objects on top of this unit. Do not situate it on a
rug or other soft surface and do not obstruct any air inlets or outlet
grilles. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that produce
heat. 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.
Do not obstruct the rear heat tunnel ventilation grille. 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. Also avoid locations subject to
vibration and excessive dust, cold or moisture. 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
a CD player or other equipment on top of the unit.
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. Any
space open at the back (such as a dedicated equipment rack)
is fine however. When a cart is used, use caution when moving
the cart to avoid injury from tip-over.
WARNING - To reduce the risk of fire or electric shock, do not expose this
unit to rain or moisture. This unit must not be used near water or
exposed to dripping or splashing water or other liquids. No objects filled
with liquid, such as vases, shall be placed on the unit. In the event,
switch off immediately, disconnect from the mains supply and contact
your dealer for advice.
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.
Grounding and polarisation
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 third prong are provided for your safety. If the provided
plug does not fit your outlet, consult an electrician for replacement of
the obsolete outlet.
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 powersupply to your home, consult your product dealer or local Power
Company.
This unit has been designed to be left in Standby mode when not in use,
this will increase the life of the amplifier (this is true with all electronic
equipment). To turn the unit off completely switch off on the rear panel.
If you do not intend to use this unit for a long period of time, unplug it
from the mains socket.
Power cord protection
The unit must be installed in a manner that makes disconnection of the
mains plug from the mains socket outlet (or appliance connector from the
rear of the unit) possible. Where the mains plug is used as the disconnect
device, the disconnect device shall remain readily operable. Protect the
power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the unit.
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.
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.
Lightning
For added protection during a thunderstorm, or when it is left
unattended and unused for long period of time, unplug the unit from the
wall outlet and disconnect the antenna or cable system. This will prevent
damage to the unit from lightning and power-line surges.
Outdoor antenna grounding
If an outside antenna or cable system is connected to the product, be
sure the antenna or cable system is grounded so as to provide some
protection against voltage surges and built-up static charges. Section
810 of the National Electrical Code, ANSI/NIPA No. 70-1984 (section 54
of Canadian Electrical Code, Part 1) provides information with respect to
proper grounding of the mast and supporting structure, grounding of the
lead-in wire to an antenna-discharge unit, size of grounding conductors,
location of antenna-discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
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 amplifier.
Attachments
Do not use attachments not recommended by your dealer as they may
cause harm to the unit. Only use the specified attachments/accessories
with this unit.
Servicing
These units are not user serviceable, never attempt to repair,
disassemble or reconstruct the unit if there seems to be a problem. A
serious electric shock could result if this precautionary measure is
ignored. In the event of a problem or failure, please contact your dealer.
Contact the service department should any of these conditions occur:
- When the power-supply cord or plug is damaged.
- If liquid has been spilled, or objects have fallen into the amp.
- If the unit has been exposed to rain or water.
- If the unit does not operate normally after following the operation
instructions, adjust only those controls that are covered by the
operation instructions.
- If the unit has been dropped or damaged in any way.
- When the unit exhibits a distinct negative change in performance.
IMPORTANT
If the unit is run at a very high level, a sensor will detect a temperature
rise and show "PROTECTION OVERLOAD" on the display. The unit will
then go into Standby mode. It cannot be switched on again until the
temperature has fallen to a more normal level.

ENGLISH
To avoid damaging the speakers with a sudden high-level signal, be sure
to switch the power off before connecting the speakers. Check the
impedance of your speakers. Speakers with an impedance of between
4 and 8 ohms (each) are recommended.
The coloured speaker terminals are positive (+) and the black speaker
terminals are negative (-). Make sure correct polarity is maintained at
each speaker connector or the sound can become weak and “phasey”
with little bass.
Prepare the speaker cords for connection by stripping off approximately
10mm (3/8”) or less (no more than 10mm, as this could cause a shortcircuit) of the outer insulation. Twist the wire tightly together so there are
no loose ends. Unscrew the speaker terminal knob, insert the speaker
cable, tighten the knob and secure the cable.
Note:
All connections are made via loudspeaker cable, except if using an
active subwoofer which would be connected via a standard RCA phono
cable. Banana Plugs (4mm standard) connected to the speaker cable
are recommended for direct insertion into the speaker terminals.
Please refer to the ‘Speaker Configuration’ section of this manual for
more information on 5.1, 6.1 and 7.1 speaker setups.
