4. PRO LOGIC
The L/C/R/RL/RR signals undergo the Pro-Logic process-
ing 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 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.
