TONE AND BALANCE

TONE
How good an audio program sounds is
largely determined by the mix of the
treble, mid and bass levels. In fact, dif-
ferent kinds of music and vocal pro-
grams usually sound better with
different mixes of treble, mid and bass.
BALANCE
A good balance of the left and right ste-
reo channels and of the front and rear
sound levels is also important.
Keep in mind that when listening to a
stereo recording or broadcast, chang-
ing the right/left balance will increase
the volume of one group of sounds
while decreasing the volume of anoth-
er.
