The Advance Acoustic X-A220 Evo power amplifier is monophonic and delivers 220 W into 8 Ω or 350 W into 4 Ω in Class AB. With High Bias enabled, it operates in Class A for the first watt, then automatically switches to Class AB. Its front panel is made of methacrylate and features an analog VU meter.

The steel chassis houses a 700 VA toroidal transformer and a heatsink for the power transistors. The power stages are based on a triple push-pull configuration of complementary NJW0281G / NJW0302G transistors. The internal layout is divided into sections, with components mounted on separate boards according to function.
