Adjusting the acoustic image (BI-PHANTOM) In most installations, the center speaker must be placed directly between the front passenger and driver. Using this function, the center channel information is distributed to the left and right speakers. This creates an acoustic image simulating a center speaker directly in front of each listener. Adjusting the center width in PL II MUSIC (see "Using the Pro Logic II Mode" on page 48), makes this function ineffective. • Avoid stopping, pausing, switching the disc, cueing, fast-forwarding or switching the audio channel of this unit while making this adjustment. The setting is canceled if the Decode mode is switched. Touch [ ] or [ ] of BI-PHANTOM to adjust the level. The level can be adjusted within the range of -5 to +5. The higher the level, the more the position of the center speaker is shifted to the sides.

The setting is canceled if the Decode mode is switched. Touch [ ] or [ ] of REAR MIX to adjust the level. The level can adjusted in five steps: -6, -3, 0, +3 and +6.

Achieving powerful high volume sound (LISTENING MODE) With Dolby Digital, the dynamic range is compressed so that powerful sound can be achieved at regular volume levels. This compression can be canceled to achieve an energetic sound with even greater power, like the sound in a movie theater. This function works only in the Dolby Digital mode.
