Effective use of the graphic equalizer
1. The graphic equalizer may be used as a simple noise re­
duction system. In the taping process, for instance,
press the upper pushbuttons of 6 and 15 kHz to give
preemphasis in the high frequency range where most
conspicuous noise and hiss components are present.
During playback, provide a tape a deemphasis by com­
pletely reversing the preemphasis response.
This process will considerably reduce the annoying back­
ground hiss from the tape while maintaining the fre­
quency response of the original signal so that it is nearly

2. Unlike floor-standing or large book-shelf speaker sys­
tems, compact one,or two way loudspeaker systems
usually have limited low and high-end response. To com­
pensate for this tendency, adjust the 60 Hz by pressing
the upper pushbutton for the low-end response, and 6
and 15 kHz for the high-end response on a trial-and-error
basis.
3. The graphic equalizer may also be used to eliminate an­
noying tape hiss or record scratch noise generated dur­
ing playback. For this use the 6 and 15 kHz lower push­
buttons.
4. Low frequency and subsonic noise, such as hum, rumble,
and low frequency vibrations, can be effectively sup­
pressed by adjusting the 60 Hz lower pushbutton.

5. When you wish to add "punch" to your music, emphasize
low and mid frequency bands of 160, and 400 Hz and 1
kHz.
6. To spotlight the vocal out of its orchestral background, in­
crease the 400 Hz, 1 kHz and 2.5 kHz by pressing the
upper pushbuttons, where most of the vocal energy is
concentrated.
