To make the sound to comfortable to hear (COMPRESSION function)
Slide the COMPRESSION switch to ON/OFF.
This function maintains the overall level of program material: explosive sounds are attenuated while lower
level sounds (footsteps, etc.) are enhanced. It is very effective for limiting high dynamic range source
material.

Note
Check carefully the volume control with the COMPRESSION function.
With the COMPRESSION function on, the sound may seem loud with when the audio signal from the
computer is comparatively low. In this case, increase the computer’s volume gradually, and set where overall
the sound is consistent. Conversely, the sound may be felt to be too low. In this case, decrease the
computer’s volume gradually, and set for the most consistent overall sound.
