CP4 STAGE/CP40 STAGE Reference Manual
Design of the CP4 STAGE & CP40 STAGE
05: Master EQ
The Master EQ screen can be used to adjust the tone of all Performances. The master equalizer on
the CP4 STAGE has five frequency bands (Low, LowMid, Mid, HighMid, and High), while that on the
CP40 STAGE has three (Low, Mid, and High). Using the parameters on this screen, you can
increase or decrease the level of signals in each of these bands.
Parameter name
Description
Shape
These parameters can be used to select a shelving type or peaking type
response for each of the equalizer’s Low and High bands. When set to
“shelv”, signals at all frequencies either above (High band) or below (Low
band) the specified frequency will be uniformly boosted or cut. Meanwhile,
when set to “peak”, signals around each band’s center frequency will be
boosted in a localized fashion.
Settings:
shelv (shelving type) and peak (peaking type)
shelv
peak
Freq
(Frequency)
These parameters can be used to set the center frequency of each band —
that is, the frequency at which the signal will be boosted or cut.
Settings:
Low band:
32Hz to 2.0kHz for shelving; 63Hz to 2.0kHz for peaking
LowMid, Mid, and HighMid bands:
100Hz to 10kHz
High band:
500Hz to 16kHz
NOTE
LowMid and HighMid settings apply to the CP4 STAGE only.
Q
(Resonance)
This parameter can be used to set the width of boosting or cutting around
the frequency set using
Freq
. As such, it can create a range of frequency
characteristic curves. If you set a large value, a narrower band of
frequencies will be boosted or cut, and the tone will change markedly
around the center frequency. If you set a smaller value, a wider band of
frequencies will be boosted or cut, and the tone will change more gradually
around the center frequency.
Settings:
0.1 to 12.0
NOTE
The
Q
parameter cannot be set for the Low and High bands when their
respective
Shape
parameters have been set to “shelv”, and its setting is
displayed as “---” in such a case.
