BASIC OPERATION
SOUND SETTINGS
The following sound quality can be adjusted.
TONE:
How good an audio program sounds is largely determined
by the mix of the treble, mid and bass levels. In fact,
different kinds of music and vocal programs usually sound
better with different mixes of treble, mid and bass.
BALANCE:
A good balance of the left and right stereo channels and of
the front and rear sound levels is also important.
Keep in mind that when listening to a stereo recording or
broadcast, changing the right/left balance will increase the
volume of 1 group of sounds while decreasing the volume of
another.
