Disabled, Front Left and Right Channels

Control Panel

For example if you are using the Microsoft “CD player” which uses the analog “CD In” connector to play CD’s or if you are using a tape deck or other external device connected to “Line In” you must select the input here to enable conversion of these stereo sources to 4 or 5.1 channels using QMSS. However if you are using an appli- cation that is not dependent on these connections such as a game, MP3 player, or a CD player that uses digital extraction rather than analog “CD In” (such as the includ- ed Siren JukeBox application) then QMSS is used to automatically convert these sources to 4 or 5.1 channels (when in 4 or 5.1 speaker mode).

S/PDIF TAB (NOT FUNCTIONAL IN 5.1 SPEAKER MODE)

This page of the Philips Seismic Edge Control Panel will control the settings for the Digital Audio output. S/PDIF is the acronym for industry-wide standard called Sony/Philips Digital Interface.This tab is linked to the settings tab. If you selected 5.1 speakers under the settings tab, S/PDIF Out is disabled and will be grayed out. Selecting Headphone, 2 or 4 speaker mode will allow you to select a desired S/PDIF Output.

S/PDIF OUT (NOT FUNCTIONAL IN 5.1 SPEAKER MODE)

Disabled

In this mode S/PDIF Out is disabled. Select one of the following options to determine what content will be sent to the S/PDIF Out connector.

Front Left and Right Channels

In this mode the same content being sent to the front Line Out speaker jack in analog format will also be sent to the S/PDIF output in digital format for applications running on your PC (MP3, games, etc.). For external inputs (CD-In or Line In), select the proper source on the "Apply Reverb/QXpander/QMSS to External Input Source" pull down menu located on the Settings tab. Use this mode if you are using digital S/PDIF speakers for your front speakers or wish to send the front speaker stereo signal to an external device connected to the S/PDIF output such as a mini-disk recorder or receiver with S/PDIF In. Please note that the volume settings on the Settings tab will have no affect on the signal on the S/PDIF output.

Rear Left and Right Channels

In this mode the same content being sent to the rear/surround Line Out speaker jack in analog format will also be sent to the S/PDIF output in digital format for applications running on your PC (MP3, games, etc.). For external inputs (CD-In or Line In), select the proper source on the "Apply Reverb/QXpander/QMSS to External Input Source" pull down menu located on the Settings tab. Use this mode if you are using digital S/PDIF speakers for your rear speakers. For proper operation you must also be in 4 speaker or 5.1 speaker mode. Please note that the volume settings on the Settings tab will have no affect on the signal on the S/PDIF output.

DVD AC3/DTS Pass-Thru

Use this mode if you wish to play DVD audio using an external AC3 or DTS decoder such as a speaker set, receiver or decoder box connected to S/PDIF Out. This mode is only available when using a compatible soft-DVD player capable of streaming AC3 or DTS data to the sound card.
