Cambridge Audio 640R user manual Introduction, Before connecting

Introduction

Thank you for purchasing this Cambridge Audio Azur range AV receiver. The 640R is designed for excellent multi-channel surround-sound 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 ReadyTM/Incognito ReadyTM outputs 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.

Before connecting
The process of setting up the 640R is first to make all the connections		ENGLISH
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.
