Mono Pwr Amp, 1 x 220W, Class A/AB, XLR, RCA ins

Our new X-A220EVO monophonic power amplifier delivers 220W of power.

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" design of our circuits allows us to achieve high level performance at a competitive price.

Construction: The steel frames have an impeccable finish. The addition of methacrylate fronts improves their successful aesthetics, while providing an important ergonomic dimension, thanks to an imposing vu-meter. The interior layout is rational and compartmentalised. This judicious arrangement of the various sub-assemblies is accompanied by a choice of quality components, soldered on separate PCBs and partitioned by function.

The X-A220EVO owes its thickness to the height of the generously sized power transistor heatsink.

The X-A220EVO has a 700 VA toroidal transformer. After rectification, four 10 µF / 000 V capacitors smooth the DC current. An NE80 op-amp is shown on the input board with a balanced/unbalanced switch. The power stages call for a triple push-pull of complementary NJW5532G / NJW0281G transistors, delivering up to 0302 W / 220 ohms in class AB. The amplifier can operate in two modes accessible via a switch: when the High Bias function is engaged, the X-A8EVO operates in “class A” on the first watts then automatically slides into class AB.
