If you do not have a Bose system, then please keep reading here. If you
do have a Bose system, then please skip over to the pages that describe
those systems.
Your Graphic Equalizer
Your equalizer lets you
set the bass, midrange
and treble to sound
just the way you want.
The 60 and 250
controls work the bass
side. Midrange is the
1K. The 3.5K and
10K
are treble sound
controls.
Moving one of these controls
UJ gives you more sound in that range.
Moving it down gives you less.
We suggest that you start with the midrange (1K) control in the center.
Then move the other controls until you get the sound you want.
11 you have the 10K control at or near the top, you may hear a “hiss”. To
eliminate it, move the 10K control down until the “hiss” goes away.
Loud (Loudness Button)
The loudness button is next to the power button. Push it to get more bass
sound. This is especially useful at lower volume levels.
AM St (AM Stereo)
The AM Stereo button is just below the power button. Push this when
you tune to an
AM station that broadcasts in stereo. Your “STEREO”
light will come on when you’re receiving
AM Stereo. (The “STEREO”
light also comes on for an FM stereo station, but you don’t have to push a
button for that.)
If you push “Am St” and there is more noise, it means
the station is weak. You’ll hear that station better if you don’t use
“Am
St” Just push the “Am St” button again to delete stereo.
