Technical Specifications ..........................................................................11

Two digital inputs are fitted allowing other digital sources to be brought

into the 740C and upsampled, the 740C then working as a very high

quality DAC.

A digital output is also fitted which can even output upsampled data at

various rates and word widths, independent from the main audio output,

which is always set at 24/384 for best sound quality.

In addition to these audiophile features Control Bus Input/Output and IR

Emitter Inputs are provided to make it easy to integrate this unit into

Custom Installation systems if desired.

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 and Azur amplifiers

in an attractive and easy to use handset.

Your CD player can only be as good as the system it is connected to.

Please do not compromise on your amplifier, speakers or cabling.

Naturally we particularly recommend amplification from the Cambridge

Audio Azur range, and in particular the new 740A Integrated Amplifier

which has been designed to the same exacting standards as this CD

player. 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
