Audio 5.Lch Signal Block - Sony DVP-M35 Operation Manual

2-11. Audio 5.lch Signal Block

The AC3 decoded signal DD-DATA C/R/F output from the MB-78 board IClOl MGA
(CXD8746) is input together with DD BCK and DD LRCK to IC203, IC204, and IC205
(CXD8750) of the AU-197 board, passed through the digital filter, and converted to the analog
signal in DAC.
The front L and R signals are then passed through IC203 of the AU-197 board, gain-controlled
at IC353 (BU4053B), and noise-eliminated at the secondary LPF IC208, IC211 (NJM4580) to
become the external output of the front L and R.
The sound L and R, and center sub woofer signals are passed through IC204 and IC205 without
being gain-controlled, and noise-eliminated in the secondary LPF IC209, IC212, IC210 and
IC213 (NJM4580) to become the external output.
