Introduction
Thank you for purchasing this Azur 840A V2 Class XD Integrated Amplifier. We hope that you will enjoy many years of listening pleasure from it.

Input 1 features a balanced input using XLRs giving optimal performance with equipment such as the matching 840C Upsampling CD player which features 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 of your amplifier in an attractive and easy to use handset.

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