5. General Audio Operation for 5.1CH
1) Overview
It receives CLOCK and DATA from MPEG DECODER(IC405) and transforms Digital signal to Analog
signal at AUDIO D/A CONVERTER(IC350) then, amplifies Analog signal (IC303, IC304, IC305)and
outputs to 5.1 CH Jack (JK300) and 2CH Jack (JK301).
After Noise Filtering Digital signal from MPEG DECODER(IC405) at HEX Inverting Gates IC(IC306), it
outputs Digital signal to Coaxial Jack (JK302).

6. General Audio Operation for 2CH
1) Overview
It receives CLOCK and DATA from MPEG DECODER(IC405) and MODE CONTROL signal from
MICOM(IC500), and transforms Digital signal to Analog signal at AUDIO D/A
CONVERTER(IC300) then, amplifies Analog signal (IC303) and outputs to 2CH Jack (JK301).
After Noise Filtering Digital signal from MPEG DECODER(IC405) at HEX Inverting Gates
IC(IC306), it outputs Digital signal.
