Philips 4-ch-091100-11-40.qxd 2000/9/11 AM 11:39 Page 44 Philips Seismic Edge DVD Playback Modes Using 4 channel surround speakers your Seismic Edge sound card can deliver true multi-channel surround sound from a compatible soft-DVD player application even if the player only supports stereo output. If the soft-DVD player is capable of providing a true 4 channel Dolby Digital downmix Seismic Edge will output 4 channels. Even if the soft-DVD player supports 4 channel Dolby Digital you may prefer using QMSS playback of DVD's because of the enhanced rear channel content it provides. If you have only stereo speakers Seismic Edge can also provide virtual surround using it's 2D to 3D remapping feature. To enable 4 speaker QMSS DVD enhancement: 1) Make sure ''4 Speakers'' is selected in the Seismic Edge control panel settings tab. 2) Open the ''control panel'' or settings menu for the soft-DVD player. 3) Select the menu or tab that controls the player's audio settings. 4) Look for a panel that allows you to select the number and type audio channels 5) Select either 2 speaker ''Stereo'' or 2 speaker ''Dolby Surround or ProLogic'' Either option will work well as the QMSS DSP algorithm does not depend on Dolby encoding. (Effectively you should follow the soft-DVD player instructions for playing back over stereo speakers even though you have quad speakers connected). 6) Close the control panel and play a DVD. Seismic Edge will detect that it is in 4 speaker mode but is only receiving two channels of audio from the DVD and automatically generate 4 distinct channels of surround sound using QMSS. To enable a 4 speaker Dolby Digital downmix : 1) Make sure ''4 Speakers'' is selected in the Seismic Edge control panel settings tab. 44
