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," page 50), 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 +6 (when setting the A.PROCESSOR mode: -5 dB to +5 dB). The higher the level, the more the position of the center speaker is shifted to the sides. The BI-PHANTOM function is turned off by touching [OFF]. • This adjustment is effective when the setting of the center speaker to SMALL or LARGE in the speaker setup settings. • This adjustment is ineffective when the speaker is set to CENTER OFF in "Setting the Speakers" (page 44). Mixing bass sound to the rear channel (REAR MIX) This function mixes the front channel audio signals to the audio signals output from the rear speakers, improving the sound in the vehicle's rear seat. • 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 REAR MIX to adjust the level. The level can adjusted in five steps: -6, -3, 0, +3 and +6. The higher the level, the more bass is output from the rear speakers. (The effect differs according to the software (DVD, etc.).) The REAR MIX function is turned off by touching [OFF]. • This adjustment is ineffective when the rear speaker setup setting is set to "OFF." • For linear PCM signals, the voice is output from the rear speaker regardless of the REAR FILL and REAR MIX setting. 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. Touch [ ] or [ ] of LISTENING MODE to select STD or MAX. STD: For powerful sound at regular volume levels MAX.: For powerful sound at high volumes • Keep the volume to a level at which sounds outside the vehicle can still be heard. Adjusting the speaker levels (OUTPUT LEVEL) The test tones help to make the volume adjustments of the different speakers. When levels are equal, a strong sense of presence can be heard from the different speakers at the listening position. • 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. 1 Touch [AUTO] of OUTPUT LEVEL. Test tone output is repeated for each of the different speaker channels. They will be repeated in the order shown below. If no operation is performed for 2 seconds, the channel switches to the next channel. Left Center Right Right Surround Left surround Left 2 While the test tone is being produced from the speakers, touch [ ] or [ ] of OUTPUT LEVEL balance the output from all the speakers. • The adjustment range for the different speakers is -6 dB - +6 dB (when setting the A.PROCESSOR mode: -10 dB to +10 dB). • Adjust based on the front speakers. • If a speaker is set to off mode, that speaker's level adjustment cannot be made. Refer to "Speaker Setup" (page 48). • When this setting is mode using Bass Engine, perform this with no disc inserted in the unit. Setting the Output Channel (OUTPUT MODE) The sound output mode of the internal DVD player can be switched between 2CH and 5.1CH. • 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 OUTPUT MODE to select AUTO or STEREO. AUTO: The sound output mode will automatically be switched between 2CH and 5.1CH according the number of channels available on the disc to be played and the contents of the SETUP items. STEREO: The sound output mode will exclusively be switched to 2CH regardless of the number of channels on the disc and its SETUP item contents. When STEREO is set, rear and front output is the same. • If this setting is switched from AUTO to STEREO, the front speaker setting of SPEAKER SETUP is switched to "LARGE." • Depending on the AUTO or STEREO setting, adjusting BASS/TRE, T.CORR, Bass Sound Cont. contents cannot be made.
