Extron MPA 401 是一款 1/4 机架宽、对流冷却的单声道功率放大器，提供 40 W rms 的输出功率。它的 UL 2043 阻燃级设计符合 UL 关于天花板安装的相关要求。这款通过能源之星(ENERGY STAR®)认证的功率放大器采用了 Extron 独特、高效的高级 D 类功率放大器设计及专利的 CDRS™（D 类波纹抑制）技术，能够提供流畅、纯净的音频波形，大大提高了传统 D 类放大器的信号保真度。为了简化集成，它配有 3 路缓冲输入，可以分别连接 3路信号源而不会改变其性能表现。Extron 的这一独特、高效的设计产生的热量极少，使功率放大器能够对流冷却并在通风条件较差或无通风的环境中运行。
