* Equalizers
The RX-7 equalizers provide low and high frequency shelving and mid-range peaking, both
boost and attenuation. The mid-range EQ center frequency can be set at any frequency
between 200Hz and 5kHz with a continuously variable frequency knob.
Fig. 19 indicates each instrument and frequency band. The equalizer operation can be made
with reference to this figure.

EQUALIZATION CHART
These sounds
are felt more
than really
heard. They
give a sense of
power. Too
much produces
a muddy
sound.
The rhythm
section appears
here. Either a fat
or thin sound can
be heard by mis-
EQ here. Too much
becomes boomy.
Bass guitar-Snare-
Toms.
Probably the most
important of all. Most
all instruments
contain harmonics
here.
300Hz boosting can
cause horn-like
sounds. 1k to 2k
sounds tinny. Too
much here sounds
like the telephone.
Upper vocal region.
Too much here will
cause great fatigue,
and loss of speech
intelligence. Reducing
3k can bring vocals
on top.
Presence range.
Great achievement
in overall level can
be had here. Too
little causes a "far
away" sound.
Sibilance
levels can be
controlled
here. Bright,
clean defini-
tion.
