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.
