Audio Systems
Your Delco@ audio system has been designed to operate
easily and give years
of listening pleasure. But you will
get the most enjoyment out of it if you acquaint yourself
with it first. Find out what your DelcoQ system can
do
and how to operate all its controls, to be sure you’re
getting the most out of the advanced engineering that
went into it.
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). And,
tall buildings or hills can interfere with FM signals,
causing the sound
to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
redu
~ --lg the treble to reduce this noise.
AM Stereo
This means the Delcoa system can receive C-QUAM@
stereo broadcasts. Many AM stations around the country
use C-QUAM@ to produce stereo, though some do not.
(C-QUAM@ is
a registered trademark of Motorola, Inc.)
If your Delcoa system can get C-QUAM@, your
STEREO light will come on when you’re receiving it.

A CAUTION:
Hearing damage from loud noise is almost
undetectable until
it is too late. Your hearing
can adapt to higher volumes of sound. Sound
that seems normal can be loud and harmful to
your hearing. Take precautions by adjusting the
volume control on your radio to a safe sound
level before your hearing adapts to
it.
To help avoid hearing loss or damage:
