UAD Powered Plug-Ins Manual - 394 - Chapter 39: Pultec Passive EQ Collection
The HLF-3C interface is very simple and includes only the three controls shown
in
Figure 120 .
Enable This toggle switch is the plug-in bypass control. When in the down position
(bypassed), plug-in processing is disabled altogether. The plug-in is engaged
with the switch is in the up position.
This switch can be used to compare the processed settings to that of the orig-
inal signal, or to bypass plug-in processing to reduce UAD DSP load (DSP
load is not reduced if UAD-2 DSP LoadLock is enabled).
Note: The behavior of this toggle switch differs from the other UAD Pultec
plug-ins. Because the HLF-3C hardware is not internally amplified, there is no
I/O circuitry modeling to maintain when the EQ portion of the circuit is by-
passed (the entire hardware unit is the EQ portion).
Low Cut This rotary switch specifies the cutoff frequency of the low cut filter. Eleven fre-
quencies are available: 50, 80, 100, 150, 250, 500, 750, 1000, 1500,
and 2000 CPS.
Tip: To cycle through the available values, click the “CPS” text label, or
shift+click the text label to cycle through available values in reverse.
High Cut This rotary switch specifies the cutoff frequency of the high cut filter. Eleven fre-
quencies are available: 1.5, 2, 3, 4, 5, 6, 8, 10, 12, and 15 KCS.
Tip: To cycle through the available values, click the “KCS” text label, or
shift+click the text label to cycle through available values in reverse.
