Azur 640A V2 integrated amplifier

More power and compatible with multi-room outputs

The Azur 640A V2 includes all the features from the original model such as oversized toroidal transformer, short path circuitry and a raft of intelligent protection systems but now has more power, 75 watts per channel (8 Ohms).

The V2 is now Incognito Ready (Level 1) and fitted with Control Bus In and Out, and an IR emitter In making it compatible with multi-room outputs.

It has new volume, tone and balance pots which are more robust and therefore give a better feel and

channel matching. New input PCB circuitry with buffering leads to better imaging.

The V2 also benefits from having new larger heatsink, updated style navigator Azur remote control with hidden discrete codes.
