M28是一款高性能的3U数字调音台。前板上配有24个输入接口，，其中16个通道可以在MIC及LINE之间进行切换；另外8个为1/4”接口的LINE通道。6个AUX输出通道中，2个可以作为监听输出镜像，另外配有2个主左、右通道。除此以外，在前板上还配置了可调增益大小的耳机1/4”接口，为监听输出。将USB闪存盘插入M28前板的USB端口上，可进行USB立体声或双通道录音及回放功能，输入跟输出通道可以作为录音源。

M28由性能强大的MARANI® DSP独家处理器所驱动，内置如Taps高达1024的FIR（主左/右通道）、效果器、闪避功能、RTA、反馈抑制、自动混音功能等一系列复杂的声音处理功能，每个输入跟输出通道上都有如参数均衡器、RMS压缩器、可调延时等。另外，每个输出通道额外配有31段图示均衡器。用户可以通过前板上的以太网端口将M28连接到PC软件上。除此以外，M28内置WIFI模块，用户可以通过WIFI将设备与PC联机，以实时监控当前的参数设置以及对机器进行控制，大大地使现场演出、录音室等使用场合的操作更加方便。一台M28可以同时在WiFi状态下连接4台PC电脑或iPad，在以太网方式连接10台PC电脑，任意一台设备上的设置更改，也会自动更新到其他连接的设备上。另外，用户可以直接在PC软件一键式进行固件升级。

使用扩展模块，M28支持额外4个输入通道的扩充，可选择为模拟、AES数字或DANTE™
