HDMI signal is selected by HDMI INPUT SELECTOR (IC3503) and
inputs to HDMI RECEIVER (IC3511).
SPDIF signal is output from HDMI RECEIVER (IC3511 78pin) to
DATA SELECTOR (IC2228) through BUFFER (IC3524). And, High Bit
Rate audio signals output from HDMI RECEIVER (IC3511 81-84pin) to
DATA SELECTOR (IC2213) through BUFFER (IC3524). These signals
are sent to DSP1 (IC5002) finally.

Digital audio signal inputs to DSP1 (IC5002). DSP1 decodes all type of
digital audio signal format which is supported by this model with S-RAM
(IC5007) and ADDRESS LATCH (IC5009, IC5010).
(IC5007) and ADDRESS LATCH (IC5009, IC5010).
When DSP1 (IC5002) finishes decoding the audio signal format, the
format name data is sent to DSP CONTROLLER (IC5208). The data is
sent to SYSTEM CONTROLLER (IC2513) and it is shown on LCD
display. (Ex. PCM, DTS-ES, etc.)

When an audio related problem occurs, please check the signal type
indicator. If it is shown on LCD display, the signal flow to DSP1
(IC5002) is good.
(IC5002) is good.

Decoded audio signal in DSP1 (IC5002) is sent to DSP 2 (IC5202).
DSP2 (IC5202) processes the sound data for several sound field effect
with S-RAM (IC5207) with ADDRESS LATCH (IC5209, IC5210). After
processing the audio data, DSP2 (IC5202) outputs the audio data to
FIELD (PROGRAMMABLE GATE ARRAY (IC2003) with four lines of
SDO1-4.

Only in speaker calibration operation with included MIC, the audio
signal passes DSP1 (IC5002) through DATA SELECTOR (IC5013).
