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
fir st,
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
c
ompromising
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 Ready TMoutputs 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 multi-
room 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.
