Introduction

Thank you for purchasing this Azur 840E Pre-Amplifier. We hope that you will enjoy many years of listening pleasure from it.

Cambridge Audio has taken the Azur 840 series to its peak with the introduction of two new models – the 840E Pre-Amplifier and 840W Power Amplifier. The 840E is a high-end pre-amplifier which uses Cambridge Audio’s new proprietary TerraPin™ modules for unprecedented audio fidelity, forming the perfect partner for the accompanying 840W power amplifier.

Other features include the use of precision resistor ladders switched by gold plated relay contacts for the volume and balance controls rather than the more common solid-state or volume potentiometer schemes. Volume is controllable in 1 dB steps over most of the range, giving very fine control, an accurate logarithmic law and superbly accurate channel balance. Input switching is also by high quality gold contact relays.

Inputs 1 and 2 feature balanced inputs using XLRs giving optimal performance with equipment such as the matching 840C Upsampling CD player which feature balanced outputs.

The casework combines massive structural rigidity with careful damping and control of acoustic resonance. An Azur Navigator remote control is also provided, giving full remote control in an attractive and easy to use handset.

We have also included support for multi-room use. By plugging in one or two external Cambridge Audio Incognito keypads and a power supply unit, this unit can become the hub of a simple multi-room system. In addition, Control Bus Input/Output, IR Emitter Input, Trigger In/Out and RS232 control are featured making it easy to integrate the 840E into a Custom Installation system if desired.

Your pre-amplifier can only be as good as the system it is connected to. Please do not compromise on your source equipment, power amplifier or cabling. Naturally we particularly recommend models from the Cambridge Audio Azur range, in particular the matching 840W Class XD™ Power Amplifier. These have been designed to the same exacting standards as this pre-amplifier. Your dealer can also supply excellent quality Cambridge Audio interconnects to ensure your system realises its full potential.

Thank you for taking the time to read this manual; we do recommend you keep it for future reference.

Matthew Bramble,

Cambridge Audio Technical Director and the 840E/840W design team
