The SAA2003 performs the sub-band filtering and audio frame codec functions in the Precision Adaptive Sub-band Coding (PASC) system. It can be used as a stand-alone decoder for playback only applications, but requires the addition of an Adaptive Allocation and Scale Factor processor (SAA2013) in order to perform PASC encoding in a DCC record system.
CODE SOT307
1. When using reflow soldering it is remended that the Dry Packing instructions in the “Quality Reference Pocketbook” are followed. The pocketbook can be ordered using the code 9398 510 34011.
