2-11. Audio 5.1ch Signal Block
The AC3 decoded
signal
DD-DATA
C/R/F output from the MB-78
board IC101
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 Land 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.
