Description
The Analog Out setting is used to match your actual speaker
setting, such as headphones, 2 speakers (or 2.1), 4 speakers
(or 4.1), 5.1 speakers, 7.1 speakers, Front Panel Headphone
and Front Panel 2 speakers (or 2.1). Xonar DX will play the
channels and do the proper 3D/Dolby sound processing
accordingly. Please select the correct speaker type for your
connected speakers.
Click this button to show the speaker test window in the right
pane. Click the "play" button to test each speaker one by one
or click each speaker manually to test.
(note: the Speaker Test function is not available on Windows
Vista due to a limitation in its audio stack.)
Clicking this button will pop up an advanced setting window
to allow you to:
–Swap center/bass outputs for 5.1/7.1-speaker set ups
-Swap Side/Surroud outputs for 7.1-speaker set ups
Check the box if your speakers are outputting the incorrect
channel. Otherwise, leave them blank.
