Servonaut SM7声组拥有采样精度和准确度很高的发动机音效，是工程卡车、载装机或其他工程机械模型的理想选择。这一来自德国的声组拥有优良的品质和性能，受到全世界范围内工程机械模型爱好者的推崇，享有很高的美誉度！与更具性价比的Servonaut SM3相比，SM7的性能更具优势。SM7在SM3的基础上新增了油泵特殊音效和消防车音效，可经由有刷电调的电机驱动端口进行采样触发，让你的工程车能在油泵启动时听到油泵音效。此外喇叭功放的功率也更大，可驱动更大功率的喇叭。与Servonaut全系列电调配合，有倒车声出现。

推荐这样搭配喇叭：
工作电压：7.2V 请使用4欧姆喇叭
工作电压：12V  请使用8欧姆喇叭

内置音效：
发动机音效(共5种)：Actros、TGA、Scania 1、Scania 2、DAF

当使用COMMANDER遥控器和CM-5000接收机时，可不依赖电调激活倒车声和档位切换声。
