Low Frequency Controls - Universal Audio Ampex ATR-102 Manual

Figure 99. Control grouping within the Pultec EQP-1A
In/Out Toggle This is a signal bypass control. It allows you to compare the processed and un-
Switch
processed signal. It does NOT reduce UAD DSP load.
In the hardware EQP-1A, the audio is still slightly colored even when the
switch is in the Out position. This is due to the fact that the signal is still pass-
ing through its circuitry. Because the plug-in emulates the hardware in every
regard, the signal will be slightly processed when this switch is in the Out po-
sition. If a true bypass is desired, use the On/Off rotary switch.
This switch enables or disables the EQP-1A altogether. You can use this
On/Off Rotary
Switch
switch to compare the processed settings to that of the original signal, or to
bypass the plug-in to reduce UAD DSP load (load is not reduced if UAD-2 DSP
LoadLock is enabled).

Low Frequency Controls

This switch determines the frequency of the low shelf portion of the equalizer.
CPS Selector
Switch
CPS is an acronym for Cycles Per Second (Hertz). Four frequencies are avail-
able: 20, 30, 60, and 100 Hertz.
Boost Knob This knob determines the amount of low shelf gain to be applied to the fre-
quency set by the CPS switch.
Attenuation This knob determines the amount of low shelf cut to be applied to the fre-
Knob
quency set by the CPS switch.
