540A/640A V2.0Integrated amplifier Azur integrated amplifier 3 Thank you for purchasing this Cambridge Audio Azur range amplifier. These version 2 models are part of our commitment to the on-going development of the Azur range. We hope that you will appreciate the results and enjoy many years of listening pleasure from them. For these version 2 models we have been able to further improve the audio quality and make them more powerful through many detailed changes and enhancements developed as a result of our on-going research programme. We have also added some new features, including support for Multi-Room use. 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 amplifier in an attractive and easy to use handset. About the 540A V2.0 The 540A V2.0 features a new preamp stage with buffered inputs for lower crosstalk and improved stereo imaging, whilst the headphone output is now provided be a separate Class A headphone driver circuit. The amplifier stage has been revised with new low-noise input transistors, special driver stage PSU regulation, a new voltage amplifier topology and separate current sources for the voltage amplifier and pre- driver stages. These enhancements to the original circuits all work to elevate the sound quality to a new level. A new heatsink and transformer are employed and the power output is now 60 watts per channel (from 50 wpc on the V1 model). About the 640A V2.0 Featuring all of the above enhancements, the 640A V2.0 also features separate transformer secondaries for left and right channels, twin rectifiers and separate PSU's for dual mono operation of the left and right power amplifiers. An even larger heatsink and transformer are employed and power output is now 75 watts per channel (from 65wpc on the V1 model). Incognito Ready / Custom Install Use Both the 540A V2.0 and 640A V2.0 now feature outputs for the new Cambridge Audio Incognito system. By plugging in one or two external Incognito Keypads and a power supply unit your V2.0 amplifier can become the hub of a simple multi-room system. In addition, Control Bus Input/Output and IR Emitter Input are provided to make it easy to integrate these units into Custom Installation systems. Your V2.0 amplifier can only be as good as the system it is connected to. Please do not compromise on your source equipment, speakers or cabling. Naturally we particularly recommend models from the Cambridge Audio Azur range, which have been designed to the same exacting standards as our amplifiers. 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. Matthew Bramble Technical Director INTRODUCTION
