M系列放大器对于便携和安装系统配置方面同样用途广泛， 4通道提供高达5000 W的功率，整齐封装在机柜中，重量略高于7.3 kg / 16 lb，是中小型音响系统灵活的、经济高效的解决方案。
作为标准配置，M系列功放采用全保护电路设计，包括：当交流电源电压超出工作范围时，交流保护关闭电源。 削波限幅器防止严重限幅的波形到达扬声器，同时仍然保持全峰值功率输出，直流保护防止输出端的次声信号。 另外，高频过载保护扬声器免受破坏性的非听觉、非音乐高频信号的影响。 最后，短路保护用于保护放大器免受输出端短路或类似事件的影响（具有自动保护复位）。
还可以通过拾取NL4输出连接器上的两个接点2 + / 2 - 在CH 1/2和CH 3/4之间获得桥接模式。当在桥式模式下运行时，功放将向最小8 ohm负载输送2500 W。
得益于这些核心技术，M系列功放的效率达到了一流标准，实现了低功耗，节省了大量资金，符合环保要求。独特的专利D类输出级设计赋予传奇般的音质，使M系列功放具有卓越的商业和实用价值。
Equally versatile in both portable and installed system configurations, and with its four channels delivering up to 5000 W neatly packed in one single rack unit weighing just over 7.3 kg / 16 lb, the M series amplifiers are a flexible, cost-effective solution for small to medium sound systems.
As standard, the M series amplifiers come with fully protected circuit design that includes: AC protection that shuts down the power supply when AC mains voltage is outside operating range. The Clip Limiter prevents severely clipped waveforms from reaching loudspeakers while still maintaining full peak power output, and the DC protection protects against infrasonic signal at the outputs. Added to this the VHF protection protects the loudspeakers against destructive non-audible, non-musical high frequency signals. Finally, the Short Circuit protection acts to protect the amplifier from short circuits or similar events on the outputs (with an automatic protection reset).
Bridge mode can also be obtained between CH 1/2 and CH 3/4 by picking up on pins 2+/2- on the NL4 output connector. When running in Bridge Mode the amplifier will deliver 2500 W into a minimum 8 ohm load.
Benefitting from these core technologies the M series amplifiers set a class standard in efficiency, leading to low power consumption, and consequently to substantial money savings, all in an eco-friendly way. The legendary sound quality given by the unique, patented Class D output stage design, make the M series amplifiers a superior commercial and practical value.
