The EFFECT switch allows you to select your preferred sound field.
With 5.1ch, 2ch, or USB is connected when "FPS" or "SURROUND" is selected, the built-in

About property of sound with the EFFECT function
 The EFFECT function may not be obtained from sound sources that do not incorporate video, such as
music CDs.
 VPT (Virtualphones Technology) simulates the average human HRTF (head-related transfer function)*.
The effect is perceived differently, depending on individual.
* HRTF = Head-Related Transfer Function. A mathematical measurement to show changes in sound
between the source and your ears.
Sound field mode and suitable sound source
This setting provides clear localization of sounds respective of image.
This is the recommended setting for FPS where locality of sounds need to be
accurately perceived. The sound is listener-friendly, natural, clear and realistic. It
is characterized by very sharply perceived localization of all channels.
This setting provides a seamless reproduction of all channels.
The overall sound is perceived more as a whole than with the FPS mode, and
provides the best sound field for playing multichannel surround games in general.
Also recommended for movie watching.
2ch sound is output.
A multichannel source (7.1ch/5.1ch) is downmixed to 2ch sound.
