Panorama
Assign front L/R signal also 
to surround channels for 
wider sound.

ON : Set.
OFF : Do not set.

Dimension
Shift sound image center 
to front or rear to adjust 
playback balance.

Center Width
Assign center channel 
signal to front left and right 
channels for wider sound.

Delay Time
Adjust delay time to control 
sound stage size.

Effect Lev.
Adjust effect signal level.

 Set  to  a  lower  level  if  the  positioning  and  sense  of  phase  of  the 

surround signals seems unnatural.

Room Size
Determine size of acoustic 
environment.

Small : Simulate acoustics of a small room.
Medium-S : Simulate acoustics of a medium-small room.
Medium : Simulate acoustics of a medium room.
Medium-L : Simulate acoustics of a medium-large room.
Large : Simulate acoustics of a large room.

“Room Size” does not indicate the size of the room in which sources are 
played.

AFDM
(Auto flag detect mode)
Detect the source’s 
surround back channel 
signal and set the 
optimum surround mode 
automatically.

ON : Set.
OFF : Do not set.

[Example] Playing Dolby Digital software (with EX flag)
• When “AFDM” is set to “ON”, the surround mode is automatically set 

to the DOLBY D + PLgx C mode.

•  To play in the DOLBY DIGITAL EX mode, set “AFDM” to “OFF” and 

“Surround Parameter” – “S.Back” to “MTRX ON”.

 Some Dolby Digital EX sources do not include EX flags. If the playback 

mode  does  not  switch  automatically  even  when  “AFDM”  is  set  to 
“ON”,  set  “Surround  Parameter”  –  “S.Back”  to  “MTRX  ON”  or 
“PLgx CINEMA”.

S.Back
Sets the method of 
generating of the surround 
back channel.

n

ON : The surround back channel is used.
OFF : No signal is played from the surround back channels.

n

Set the decoding method for the surround back channel.
DSCRT ON : Play the surround back signals included in the 7.1-channel 
source.
MTRX  ON  :  Generate  and  play  the  surround  back  signals  from  the 
surround channel signals.
ES MTRX

z

1

 : Generate and play the surround back signals from the 

surround channel signals of the DTS source.
ES  DSCRT

z

2

  :  Play  the  surround  back  signals  included  in  the 

6.1-channel DTS source.
PLgx  CINEMA

z

3

  :  Generate  and  play  the  surround  back  signals  by 

decoding the signals in the Dolby Pro Logic gx Cinema mode.
PLgx  MUSIC  :  Generate  and  play  the  surround  back  signals  by 
decoding the signals in the Dolby Pro Logic gx Music mode.
OFF : Do not play the surround back channel.

z

1  This can be selected when playing DTS sources.

z

2  This can be selected when playing DTS sources including a signal to 

identify discrete 6.1-channel signals.

z

3  This can be selected when “Speaker Config.” – “S.Back” (vpage 47) 

is set to “2sp”.

• This can also be set by pressing 

.

• If  the  source  being  played  contains  a  surround 

back  signal,  the  decoder  type  is  automatically 
selected by the AFDM function. Set “AFDM” to 
“OFF” to switch to your preferred decoder.

If the setting in “Speaker Config.” – “S.Back” (vpage 47) is “None”, 
“S.Back” is not displayed.

Front Height
Determine whether to use 
front height channel.

ON : Audio is output from the front height speaker.
OFF : Audio is not output from the front height speaker.

• “Front Height” is displayed with the settings listed below.

• When “Pre Assign” (vpage 46) is set to “Front Height”.
• When the “Speaker Config.” – “Front Height” setting (vpage 47) is 

set to other than “None”.

• “Front  Height”  cannot  be  set  if  the  HD  Audio  source  being  played 

includes a front height channel. In this case, the Front height channel 
is played back without decoding in PLgz mode, using the input signal.
