EQ Enable
This is the EQ enable control. Like the original hardware, the signal
is still colored even when this switch is in the out (down) position, be-
cause the signal is still passing through the I/O circuitry. If a true by-
pass is desired, use the Bypass/Gain knob.
Bypass/Gain
The function of this control differs between the newer EQP-1A and the Legacy
version, as described below.
Pultec EQP-1A
This dual purpose knob is an output gain control, and the plug-
in bypass control. The available output gain range is ±12 dB.
Rotate the control fully counter-clockwise to disable plug-in
processing and reduce UAD DSP load (DSP load is not re-
duced if UAD-2 DSP LoadLock is enabled).
Tip: Click the “OFF” text label or the red power lamp to toggle between by-
pass and the previous value.
Tip: Click the “0” text label to set the gain to 0 dB.
Pultec EQP-1A Legacy
This is the plug-in bypass control. The knob can be used to com-
pare the processed settings to that of the original signal, or to dis-
able the plug-in to reduce UAD DSP load (DSP load is not reduced
if UAD-2 DSP LoadLock is enabled).
Note: Output gain is unavailable on the Pultec EQP-1A Legacy plug-in.
Low Frequency
Controls
Low Frequency
This switch determines the frequency of the low shelf portion of
the equalizer. Four frequencies are available: 20, 30, 60, and
100 CPS.
Tip: To cycle through the available values, click the “CPS” text
label, or shift+click the text label to cycle through available val-
ues in reverse. This function is unavailable with the Legacy ver-
sion of the plug-in.
