The selected switch is highlighted in green, or the bar on the
upper side is highlighted in yellow.
(b) Tone and balance
How good an audio program sounds to you is largely
determined by the mix of the treble, mid
−range, and bass
levels. In fact, different kinds of music and vocal programs
usually sound better with different mixes of treble, mid− range,
and bass.
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 if you are listening to a stereo recording or
broadcast, changing the right/left balance will increase the
volume of one group of sounds while decreasing the volume
of another.
