POWER & FINESSE

Our new X-A220EVO monophonic power amplifier delivers a power of 220W. It is ideally combined with our X-P500 preamplifier to form a highly musical hi-fi system. Our technical mastery combined with the most «audiophile» possible design of our circuits allow us to achieve high level performance at a competitive price.
Construction: The steel frames have an impeccable finish. The addition of methacrylate facades enhances their successful aesthetics, while by providing a significant ergonomic dimension, thanks to an imposing view-meter. The internal layout is rational and compartmentalized. This judicious arrangement of the different sub-assemblies is accompanied a choice of quality components, welded on separate PCBs and partitioned by function. The X-A220EVO owes its thickness to the height power transistor heat sink with generous dimensions.
The X-A220EVO has a 700 VA toroidal transformer. After rectification, four capacitors of 10,000 µF / 80 V smooth the direct current.
An NE5532 operational amplifier is shown on the input board with balanced and unbalanced switch.


The power stages call for to a triple push-pull of complementary NJW0281G / NJW0302G transistors, delivering up to 220 W / 8 ohms in class AB. The amplifier can operate in two modes accessible via a switch: when the function «High Bias» is engaged, the X-A220EVO operates in «class A» on the first
watts then automatically slides into class AB.
