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.

4. PRO LOGIC
L/C/R/RL/RR は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。
Dolby Digital Multi 入力時は、 通常の Dolby Digital Normal と
同じ動作をします。
PRO LOGIC I、II デコード時は、LFE は出力されません。
