Our new X-A220EVO monophonic power amplifier delivers 220W of power into an eight ohm load.
Two of the X-A500’s combined with our X-PXNUMX preamplifier to form a highly musical hi-fi system at an exceptional value.
Engineering expertise in the design of our circuits allows us to achieve high level performance at a competitive price.
Construction: The steel frames provide a stable foundation. The addition of a methacrylate front panel results in a beautiful looking design showcasing the prominent Vu Meter. The interior layout is strategic and compartmentalized. This judicious arrangement of the various sub-assemblies and choice of quality components, soldered on separate PCBs and partitioned by function provide the basis for excellent sound quality.
The X-A220EVO’s substantial height follows the requirement 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 Watts into 220 ohms 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.
