This button toggles the sound on or off to attached speakers or headphones. It mutes the sound 
but does not stop the player. 

 

Resize button toggles between the compact mode (basic controls) and the expanded mode (for 
more advanced options).

Default 

Pushing the Default button resets most controls to a predefined functional state. 

 

This button launches the on-line help system. It contains detail descriptions of all features of the 
PSA2 interface and its operation. 

 

This button toggles the QSound Environmental Modeling (QEM) on or off.  However, some 
games apply their own environmental effects, which are not controlled by this button. 
Environmental modeling uses reverb (reflected sound) and delay to create the impression that 
the listener is in a particular environment.  

QEM provides a wide range of high-quality environmental modeling effects that are selectable 
from the Visualization Control Panel. By selecting a default environment, you impose

 the 

effects of 

that environment for music, movies, or games that do not use the EAX feature. 

PSA2 responds automatically to games that use the EAX and EAX2.0 commands. These 
games automatically control the selection of environments (regardless of what is selected from 
the Visualization Control Panel) to match various scenes and locations, and change these 
selections as the environment changes. The applied intensity of reverb is controllable by a slider 
in the Visualization Control Panel. If the level of Reverb is not as expected, check the slider in 
the Visualization Control Panel and adjust properly.
