Contour modulation is a technique in which a phase-modulated signal waveform and amplifier output impedance work together to maintain higher efficiency over a sizable output power back-off.

轮廓调制结合了一种相位调制信号的波形和放大器的输出阻抗，可在某个较大型输出电源关闭后保持更高的效率。

Setup is straightforward, although you may have to do some running back and forth between the hefty (they include an amplifier) white ZonePlayers if you're doing it alone.
