ANALOG BYPS [Remote control code: 7A—90(PRG 9)]
• 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/RC, FL/FR, RL/RR and SWFR signals are output through DSP (see the signal path
in the figure below) without using the external DRAM. (Head margin included)
