(In the case of multi-ch source)
• AC3D2av outputs signals using DOLBY DIGITAL/dts decode operation.
• DSP6#1 outputs the L/R signals to L/R (SD610), RC (SD615, L only), C/LFE to C/LFE (SD611), LSt/
RSt to RLdr/RRdr (SD612). Also, it outputs L/2 + R/2 to FL/FR (SD614) through the external RAM.
• DSP6#2 outputs the output signals of DSP6#1 to L/R (SD620), FL/FR (SD622), SWL/SWR (SD624).
Also, it outputs C/RC and RL/RR to C/RC (SD621) and RL/RR (SD623) through the external RAM.
FULL BIT [Remote control code: 7A—92 (TUNER A/B/C/D/E)]
The head margin is unused and the digital data is output in full bit.
The same applies as “2ch/MULTI” 0dB” except that the digital data is output in full bit at D/A.
