S series are equipped containing quite a number of functions such as USB ports，MP3 player／recorder，24BlT DSP effectors, The whole series has three models. All functions are the same except for different input channels.

S-1 2 is with 12 channel input，among which 10 channels are mono input channels, and 2 channels are stereo input channels．

S-12  designed for machine cabinet installation．

No-noise pre-amplifier with extremely low distortion and a very wide gain range, extremely high dynamic response and musicality；

Pure 3-band equalizer with its mid-band as parametric equalizer, correct musical control power；

Stereo USB record/play port can be directly connected to PC/MAC to record and replay；

MP3 player/recorder is compatible with multi audio format; SD/USB ports provide good sound quality and concise man-to-machine communication interfaces；
