SMPS
Main System uses Digital Signal Processor(TMS320DA788B).
There are main circuit blocks such as AMP, DSP, POWER etc.
All displays is registered by LED.
Serial Interface between Ics is operated with various protocol over the whole system.
DSP(TMS320DA788B) implement DSP(TMS320DA788B) audio decoding function by 12s.
Power, proper for each part, will be generated by SMPS.
Power On/Off by Micom port is possible.
Function and sound field can be controlled by remote controller and keys.
