The process of setting up the 651R/751R is first to make all the connections
to your speakers and source equipment and then set the unit up via its OnScreen Display (OSD). There are various settings and adjustments that need
to be made before the 651R/751R 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
‘651R/751R setup’ section of this manual first, starting on page 16.
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 your 651R or 751R AV Receiver. We are confident
that you will enjoy many years of listening pleasure from it. Like all
Cambridge Audio products the 651R/751R adheres to our three core
principles – stunning performance, ease of use and incredible value.
As such, the seven audiophile grade fully discrete class AB 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 ensures that the 651R/751R 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 multichannel music sources.
A full range of HDMI, digital and analogue inputs are fitted. These allow the
connection of suitably equipped Blu-ray players, DVD players, satellite/settop boxes and games consoles for decoding into stereo, stereo + sub or
various digital surround formats.
The latest formats are supported including Dolby True HD, Dolby Digital Plus,
DTS-HD Master Audio and DTS-HD High Resolution Audio in 5.1 or 7.1
variants. In particular, support for the true lossless Dolby True HD and DTSHD Master Audio formats provides unprecedented audio fidelity from Blu-ray
discs.
Various HDMI 1.4 features are supported including 3D TV and deep-colour
pass-through from suitable sources and Audio Return from TVs with this
feature.
The 651R/751R is also capable of decoding encoded analogue or digital
stereo sources in Dolby Pro Logic® II or IIx and DTS Neo:6, for a convincing
and effective surround experience from a matrix encoded stereo source.
Sophisticated post-processing of 5.1 digital material is also possible with
Dolby Pro Logic IIx or DTS Neo:6 to turn these formats into 7.1.
Alternatively Dolby Pro Logic IIz processing allows height channel generation
from Stereo or 5.1/7.1 material for an alternative 5.1 + Height presentation.
Conventional analogue stereo inputs allow the connection of audiophile CD
players and the like, and an Analogue Stereo Direct mode with no processing
ensures the very best possible stereo reproduction for these.
The 651R/751R also carries a 5.1/7.1 channel analogue input. This feature
allows for the connection of a DVD-Audio or SACD player equipped with a 5.1
output and is compatible with any future external 7.1 audio formats.
As well as the full complement of audio inputs, the 651R/751R performs
Composite, S-Video, Component Video and HDMI switching with transcoding
and scaling (up-converting) of all analogue video to HDMI.
A Zone 2 output allows the Surround Back Amplifiers to be used to power
another Zone if these are not being used for 7.1 output in the Main Zone.
Alternatively if you wish to use all 7.1 channels in the Main Zone a separate
power amplifier and speakers can be connected to the Zone 2 preamp
outputs.
Both Main and Zone 2 remotes are supplied with the 651R/751R.
Audyssey 2EQ®, Audyssey Dynamic EQ®, Audyssey Dynamic Volume®with
Autosetup help achieve the best performance in your particular room and
with your speaker setup.
An RS232 port and IR Emitter In also make it easy to integrate the
651R/751R into a Custom Install situation.
The 651R and 751R share all the extensive features above. The 751R differs
from the 651R by being more powerful, having one extra HDMI 1.4 input on
the rear and an additional HDMI 1.3 In on the front panel. The 751R also
features Anagram Technologies ATF up-sampling on all channels.
This is performed by a third DSP (Digital Signal Processor) over the two used
in the 651R which converts all digital audio to 24-bit/192kHz with
comprehensive jitter suppression before conversion by the DACs.
Finally the 751R also features a 24 Bit Asynchronous USB Audio input
capable of up to 24-bit/192kHz Audio from Mac and PC.
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.

Introduction
Before connecting
ENGLISH
Remember your 651R/751R 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
Blu-ray players, digital and analogue iPod docks, Network and CD players
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.

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

in 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 cords 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

are digital only sources.
Follow Main
Sends an Analogue 2 Channel down-mix (L+C, R+C) of the source selected in
the Main Zone to Zone 2.
This is useful if you want to listen to the same thing in both Zones (for a party
perhaps) or wish to hear digital or surround sources in Zone 2 which cannot
be directly selected by Zone 2.
Because the downmix is created from the main zones decoded output any
source selected in the main zone including those connected by digital
(opto/coax) and HDMI inputs can be sent to Zone 2 in this way.

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 and 7.1 speaker setups.
