OPERATING THE GRAPHIC EQUALIZER
3) COLORING
THE REPRODUCED
SOUND
All instruments and vocals have their own frequency band, as
shown in the figure.
By moving the controls up or down, the volume of the in-
struments preferred can be boosted or other instruments can
be attenuated.
For instance, it is possible to boost the 40 ~ 63 Hz frequency
and give the bass drum a greater ''punch'', or boost the 400
Hz ~ 1 kHz frequency and position the vocals at the front.
When
the 6.3 ~ 10 kHz frequency is boosted, the cymbals
and "high hat' sound much clearer.
Instruments and vocals have a great many harmonic com-
ponents along with the fundamental frequency band so you
can have lots of fun operating the 17 controls to achieve the
sound of your choice.
NOTE:
{n order to protect the speakers from damage resulting from power
overload, do not excessively increase the stereo amplifier's volume
fevel when boasting the treble range on this unit.
4) RECORDING TECHNIQUES USING
GRAPHIC EQUALIZER
Coloring the sound of vocals or instruments
|
The sound of vocals and instruments can be colored at will by
operating the controls. For instance, when the 400 Hz ~ 2.5
kHz controls are raised and the other controls lowered, peo-
ple's voices sound as if heard on a telephone.
Preventing howl during mixing play
i
Any irritating howl during play can be prevented by lowering
the knob corresponding to the frequency band in which the
howl occurs.

A sound with a greater "punch" can be recorded for playback
on car stereo equipment if the ultra-low-range, which is hard
to hear, is cut out and the mid-range is boosted.
