Note: (SDOxx) represents a terminal name of AC3D3.
The shaded square ( ) means that the element included in it does not operate.
ANALOG BYPAS [Remote control code: 7A—88(PRG 1)]
• The input mode is fixed to use the analog (A/D) system.
• The L/R signal is output through the analog bypass without using the DSP section.
• C/SWFR and RL/RR signals are output through DSP (see the signal path in the figure
below) without using the external DRAM. (Head margin included)
