2. WAVEFORMS & TIMING OF MAIN SIGNAL LINES
2.1 Processor
2.1.1 Audio system
Note: Switch to Digital Input mode by connecting the optical cable
to DIGITAL IN 1 or 2, and pressing the INPUT key.
Switch to Analog Input mode by connecting the audio cable
to LINE IN, and pressing the INPUT key.
• Master clock
MCK (IC12-104pin) : 12.288 MHz (fixed)
MCKADDA (IC5-6pin) : 12.288 MHz (fixed) when in analog
input mode;
When in Digital Input mode, 12.288 MHz for an input source
sampling frequency of 48 kHz.
11.298 MHz for an input sampling frequency of 44.1 kHz; 8.192
MHz for an input sampling frequency of 32 kHz
• DIR-DECODER period
Check LRCK (IC11-12pin), BCK (IC 11-14pin), INDATA (IC11-
10pin).
At power-ON, and in Digital Input mode, any playback source is
okay.
Monitor view is shown in Fig. 1 and detailed timing is shown in
Fig. 2.

• DECODER-MAIN DSP period
Check LRCK (IC11-12pin), BCK (IC 11-14pin), FLRSG (IC11-4pin),
SLRSG (IC11-5pin), CLFSG (IC11-6pin), OTHSG (IC11-7pin).
The playback source at power-ON, and Digital Input mode is Dolby
Digital or DTS, or a 5.1ch source for MPEG-AAC.
The view on the monitor when OFF or VIRTUAL FRONT is se-
lected with the OUTPUT key is shown in Fig. 5. The detailed timing
is shown in Fig. 6.

At power-ON, and Digital Input mode or Analog Input mode, any
u163
playback source is okay.
