(b) Automatic sound levelizer
When the audio sound becomes difficult to be
heard due to road noise, wind noise, etc. dur-
ing driving, touch the "ASL" switch. The sys-
tem adjusts to the optimum volume and tone
quality according to the noise level.
(c) 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 lev-
els is also important.
Keep in mind that if you are listening to a ste-
reo recording or broadcast, changing the
right/left balance will increase the volume of
one group of sounds while decreasing the
volume of another.
