What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Cambridge 540C v2

As with previous Azur CD players, the 540C V2.0 make use of a custom Cambridge Audio servo solution and transport, at the heart of which is a VLSI (Very Large Scale Integration) circuit which dynamically adjusts in real time the focusing, tracking and output level of the laser for the maximum retrieval of digital information. To ensure the very best performance there are also multiple separate power supplies for the D/A converter circuitry, audio filters, clocks and other stages, as well as extensive use of low impedance film capacitors.
For the Version 2 models, we have significantly upgraded and improved the Digital to Analog stages as well as the anti-aliasing filters for even better sound quality and have added features that allow these products to be used in Custom Install applications. 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 CD player in an attractive and easy to use handset.
About the 540C V2.0
The 540C V2.0 now employs a WM8740 24 bit/192 kHz capable Digital to Analog converter from Wolfson Microelectronics. This very high quality part is coupled to a new three pole Double Virtual Earth Balanced filter design for very low noise and distortion. A new toroidal transformer is now fitted giving lower noise and less waveform distortion, for quieter PSU operation. Finally, to allow seamless integration with multi-room entertainment systems, a Control Bus input and output have been fitted, as has an IR emitter input.

Cambridge 540C v2 - five star CD player
The Azur 540 C boasts performance, build quality and a specification to embarrass not just its immediate rivals, but many CD players costing at least twice the price.
New features include an upgraded DAC abd Control Bus connections for easier multi-roomcontrol
Electronics sit on a low resonance, acoustically damped chassis and like all Azur products, the 540C is housed within a solid aluminium fronted case.
