Subject: | How to Fade All the Audio to the Rear Speakers When Playing a DVD |
Models: | 2007 GMC Acadia with Navigation Radio UZR |
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Fading with a Bose® Surround Sound System
When using fade in 5.1 Surround mode, the left front and right front speakers will fade rearward, leaving the center front speaker unaffected until the last fade step, then all front speakers will mute.
If the Rear Seat Audio (RSA) is turned on, the radio disables fade and mutes the rear speakers. When fading full rearward, you may want to select a stereo mode rather than 5.1. Stereo mode allows full audio content, center channel, voices, etc., to be faded rearward for rear occupants using vehicle speakers.
The following methods allow for switching 5.1 surround sound into a 2 channel stereo mode:
Note: Some DVD-Video discs only contain Dolby® Digital 5.1 (AC-3) or DTS 5.1 audio tracks and may not allow conversions into stereo modes.
This information can be found in the owners manual for the Navigation radio under "Fading With a Bose® Surround Sound System"
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
