Adjusting the Bass
The BASS control adjusts bass
sounds. Turn it up to make them
louder. Turn it down to make them
quieter. Normally, it should be set
midway.

midway.

both treble and bass are reinforced
when the volume is turned down low.
Use this button according to the music
source and according to the listening area. Its purpose is
to enrich the natural sound effects of both the treble and
bass.
