The L/C/R/RL/RR signals undergo the Pro-Logic processing and C/RL/RR signals are output through Sub DSP-DRAM.
Main DSP is selected for MAIN L/R output.
Using the sub-menu, it is possible to select PRO LOGIC I, II (Movie). The Auto Input Balance function is always off.
When dts/AAC input is used, the signal is decoded by CS49329 and the L/R signal undergoes the Pro-Logic processing.
When the Dolby Digital Multi input is used, the function is the same as in the Dolby Digital Normal mode.
The LFE signal is not output when decoding in the PRO LOGIC I, II mode.
