UAD Powered Plug-Ins Manual - 389 - Chapter 39: Pultec Passive EQ Collection
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.
