• 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
block.
• C/SWF, FL/FR, RL/RR signals are output through DSP (see the signal path in
the figure below) without using the external DRAM. (Head margin included)
Head margin:
Center: -6dBFS, Rear Center: -3dBFS, FL/FR: -6dBFS, RL/RR: -12dBFS,
SWFR: Add L/R signal at -20dBFS.
