AUTO

When a signal flag that can be recognized by this unit is 
input, this unit selects the optimum decoder to play back 
the signal in 6.1 channels.
If this unit cannot recognize the flag or no flag is present 
in the input signal, it cannot automatically be played in 6.1 
channels.

You can select from the following decoders depending on 
the format of the source you are playing.

OFF

Decoders are not used to create 6.1 channels.

• Some 6.1-channel compatible discs do not have a signal flag 

that can be automatically detected by this unit. When playing 
these kinds of discs in 6.1 channels, select a decoder manually 
from “PLIIx Music”, “EX/ES” or “EX”.

• 6.1-channel playback is not possible even if you press EXTD 

SUR. in the following cases:
– when “SUR. LR” (see page 70) or “SUR. B” (see page 70) is 

set to “NONE”.

being played.

– when the source being played does not contain surround left 

and right channel signals.

– when a Dolby Digital KARAOKE source is being played.
– when “2ch Stereo” (see page 36) or “DIRECT STEREO” (see 

page 37) program is selected.

• When this unit is turned off, this setting will be reset to 

“AUTO”.

• The Pro Logic IIx decoder is not available when “SUR. B” is set
