: Adjustable range.

When set to 5, nothing is subtracted from the left and 
right channels. When set to 0, the left and right chan-
nel levels are halved (–6 dB), making the center 
channel more dominant, particularly useful when the 
listener is off-center.

This function has no effect on the level of the center 
speaker.

 

The following Panorama, Dimension, and Center Width 
parameters can only be adjusted while the PL II Music or 
PL IIx Music listening mode is selected.
These parameters cannot be adjusted if you’re using the 
Pro Logic IIx listening mode for 6.1-channel playback 
from a 5.1-channel source.

With this function, you can extend the front stereo image 
to the surround speakers to provide a “wraparound” 
effect, especially useful when not much sound is being 
output by the surround speakers.

 

■

 

With this function, you can move the soundfield back-
ward or forward.

 

 Adjustable range.

When set to 3, the soundfield is in the normal posi-
tion. Choose a lower setting to move the soundfield 
forward Choose a higher setting to move it back-
ward.

If the stereo image is too wide, or there’s too much sur-
round information, try moving the soundfield forward to 
achieve a better balance. If the stereo image is too nar-
row, or it sounds almost like it’s in mono, try moving the 
soundfield backward.

With Pro Logic II/Pro Logic IIx decoding, the center-
channel signal is normally output by the center speaker. 
If a center speaker is not used, the decoder divides the 
center signal equally between the front left and right 
speakers, producing what’s known as a “phantom” cen-
ter. With this function you can choose to have the center-
channel signal output by the center speaker only, by the 
front left and right speakers only (“phantom” center), or 
by a mix of the two.

 

 Adjustable range.

When set to 0, the center-channel signal is output by 
the center speaker only. When set to 7, it’s output by 
the front left and right speakers only (“phantom” 
center).

In home theaters, adding some width to the center chan-
nel can improve the balance between the center and front 
left and right speakers. Most stereo material will benefit 
from appropriate use of this function.

The following table shows the display indicators for each 
supported digital signal format.

Normally, the AV Receiver detects the signal format 
automatically. However, if you experience either of the 
following issues when playing PCM or DTS material, 
you can set the signal format to PCM or DTS:
• If the beginnings of tracks from a PCM source are cut 

off, try setting the format to PCM.

• If noise is produced when fast forwarding or reversing 

a DTS CD or LD, try setting the format to DTS.

 

the DTS or PCM indicator, 

depending on which format you have set, flashes, 
and only signals in that format are output. Digital 
signals in other formats are ignored.

 

the format is detected automati-

cally. If no digital input signal is present, the cor-
responding analog input is used instead.
