Pro Logic - Yamaha AVR-S80 Service Manual

3. PRO LOGIC

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.
The LFE signal is not output when decoding in the PRO
LOGIC I, II mode.
