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.

L/C/R/RL/RRはYSS938によりプロロジック処理され、
C/RL/RRはSub DSP-DRAM経由で出力されます。
MAIN L/R出力にはMain DSPが選択されます。
サブメニューでPRO LOGIC I、II （Movie） を選択可能で
す。常時Auto Input Balance offです。
dts/AAC入力時はCS49329でデコード後、L/Rはプロロ
ジック処理されます。
Dolby Digital Multi入力時は、通常のDolby Digital
Normalと同じ動作をします。
