2-7 Audio circuit description
2-7-1 Outline
The audio data transmitted from A/V decoder(VIC1:LC6120P) are converted into analog signal via audio D/A
converter and outputted through power filter and amplifier. DVD audio is outputted after division into two cases
that only 2 channels(L/R channel) are used and 5.1 channel of AC3 is used. CD and VCD are outputted with only
2 outputs(L/R channel).
If DVD of 2 channels is used, rear L/R channel, center channel and subwooder channel are mixed and outputted
in 2 channels. CD and VCD are outputted only in 2 channels in stereo.
The digital signals(IEC-958 Output) outputted from A/V decoder are outputted to digital amp and AC-3 amp
through optical jack(opt) and RCA jack(RC45).
