LF Boost
This knob determines the amount of low shelf gain to be applied to the fre-
quency set by the CPS switch.
LF Attenuation
This knob (“ATTEN”) determines the amount of low shelf cut to be applied to
the frequency set by the CPS switch.
Background
In the documentation supplied with hardware version of the EQP-1A, it is rec-
ommended that both Boost and Attenuation not be applied simultaneously be-
cause in theory, they would cancel each other out. In actual use however, the
Boost control has slightly higher gain than the Attenuation has cut, and the fre-
quencies they affect are slightly different too. The EQ curve that results when
boost and attenuation are simultaneously applied to the low shelf is an addi-
tional feature.
High Boost
Controls
High Frequency
This switch determines the frequency of the high boost por-
tion of the equalizer. Seven frequencies are available: 3, 4,
5, 8, 10, 12, and 16 KCS.
Tip: To cycle through the available values, click the “KCS”
text label, or shift+click the text label to cycle through avail-
able values in reverse. These shortcuts are unavailable with
the Legacy version of the plug-in.
HF Q
This knob sets the proportion of frequencies surrounding the
center frequency (determined by the KCS switch) to be af-
fected by the high boost (this is a bandwidth control). Lower
values yield a narrower band and effect fewer frequencies.
