Introduction

Thank you for purchasing this Cambridge Audio 540R AV receiver. It represents Cambridge Audio's first move into the exciting world of multi- channel sound. It stems from a tradition of over 30 years of producing stereo amplifiers and holds true to the Cambridge philosophy of excellent performance at the best possible price. We hope that you will enjoy many years of happy and rewarding ownership.

About this AV receiver

The 540R is designed to maximise multi-channel performance without compromising on stereo reproduction. As such, the six, 80W discrete amplifiers are kept as separate as possible from the processing and input stages. An oversized power supply ensures that the 540R can maintain a high power output into difficult electrical loads to ensure a powerful and effortless sound.

A full range of Digital and analogue inputs are fitted to the 540R. The four Digital inputs allow for the connection of suitably equipped DVD players, satellite boxes and games consoles for decoding into digital surround formats. In addition, there are conventional stereo inputs for CD players and the like to ensure the best possible stereo reproduction. The 540R is also capable of decoding your stereo sources in Dolby Pro Logic® II (Pro Logic is a registered trademark of Dolby Laboratories), for a convincing and effective surround experience from a stereo source. This ensures sources such as analogue televisions and VCR's can make full use of the 540R's surround capabilities.

In addition to the stereo analogue input, the 540R also carries a seven- channel analogue input. This feature allows for the connection of a DVD Audio or SACD equipped player to the 540R. This means that the 540R is fully equipped to make the most of these exciting new music formats.

As well as the full complement of audio inputs, the 540R also performs Composite, S-Video and Component Video switching. This means that the 540R can be used as a hub to carry video signals in addition to the audio ones. For example, this would enable two Component Video equipped items to be connected to a single component input on your television or monitor, meaning more items can be connected to fewer high quality inputs on your television.

Last, but by no means least, is the fitment of pre-outs to the 540R. This means that an existing stereo amp can be retained to drive the front channels or indeed every channel can be driven by a separate power amplifier and the 540R simply used as a processor and pre-amp. This feature allows for the retention of existing quality stereo amps and allows for a degree of additional upgrading.

Now we invite you to sit back, relax and enjoy!
