Engine 400 是一款出色的 D 类高保真解决方案，在紧凑的模块中提供高达 400W 的功率，仍然允许设计人员通过滤波器和电源设计优化声音特性。
Exicon lateral MOSFETs are aimed at high-end hi-fi amplifiers, as they can be naturally biased towards the A region of a class AB amplifier for exceptional audio performance.
The STD03N and STD03P Darlington transistors are another good choice. Both feature built-in temperature compensation for the bias circuit, which reduces distortion and prevents thermal runaway.
The Engine 400 is a great Class D solution for hi-fi, delivering up to 400W in a compact module that still allows the designer to optimise sound characteristics with the filter and power supply design.
