(In the case of multi-ch source)
• AC3D3 outputs signals using DOLBY DIGITAL/dts decode operation.
M, C, R, SW CH [Remote control code: 7A—89 (PRG 2)]
• The input signal is automatically identified and switched in the priority order of dts

DOLBY DIGITAL
➝
PCM AUDIO
➝
Analog (A/D) according to the signal detection.
• L/R, 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)
