Dimension
This setting adjusts the depth of the surround soundfield. Depending on the level you chose, it has the affect of putting your listening position closer to the front of the room, or further back into the room’s acoustical environment. This is a highly subjective adjustment that may also require some experimenta- tion before you find the right setting for your room and listening preferences. The setting also allows you to compensate for overly “dry” recordings (those with little or no sense of reverberation or “space”) and for those with a more reverberant sound.
To adjust Dimension:
1.From the Surround Config menu, press or to move the cursor to dimension.
2.Press the and buttons on the front panel or remote to adjust Dimension anywhere from

The factory default setting of 0 is neutral and in many cases you will find it the most enjoyable.
The 1, 2, and 3 settings decrease the sense of depth and reverberation by “placing” you further towards the front of the acoustic environment.
Note: The Panorama, Dimension and Center Width adjustments may be made while any mode is selected, but they only take effect when the Dolby Pro Logic II Music or Dolby Pro Logic IIx Music modes are in use.

Channel Calibration
Next we will begin the channel calibration process, but first, a bit of background is important. “Calibration” means setting the playback levels of each channel so that they have equal volume at your prime viewing/listening position. If one or two channels are louder than the others, surround effects will be less convincing. The use of a constant level test tone that cycles from one speaker to another allows you to adjust individual channel levels more accurately.
Although it’s possible to set channel levels by ear, we don’t encourage this prac- tice. Instead, use an SPL (sound pressure level) meter. Radio Shack and other retailers offer SPL meters that are inexpensive and reasonably accurate.
Once the playback levels are properly set and you’re enjoying a movie or music selection, any level differences you hear are intentional – they’ve been “engi- neered into” the audio track for a specific reason.
To calibrate channel levels:
1.Press the MENU button on the front panel or the remote to display the Main Menu.
