UAD Powered Plug-Ins Manual v5.2 - Just Music

Note: Whether gain or attenuation is applied is determined by the Mid Type
control.
Mid Type
Mid Type specifies whether the midrange band is in Peak or Trough
mode. When switched to Peak, the Mid Gain control will boost the
midrange. When switched to Trough, Mid Gain will cut the midrange.
Note: When using Trough, a 1 dB loss occurs on the overall output of the plugin.
This is normal; the behavior is the same in the original hardware.
High Shelf Gain
The High Shelf Gain knob offers fixed frequency shelving
equalization at 10kHz. This stepped control can cut the treble
by –3dB or –6dB, or boost it in 2dB increments up to
+16dB.
EqCut
This switch is an EQ bypass control. It allows you to compare the
processed and unprocessed signal. The EQ is active when in the
“in” (up) position.
The EQ is bypassed when in the “out” (down) position. EqCut does not reduce
UAD DSP load.
In the original Helios hardware, the audio is still slightly colored even when
the EQ switch is in the Cut position. This is due to the fact that the signal is
still passing 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 Cut position. If a true bypass is desired, use the Line switch instead.
Phase
The Phase switch reverses (inverts) the signal by adding a 180° phase
shift. When the switch is in the “Inverted” (up) position, the phase is reversed.
Leave the switch in the “Normal” (down) position for normal
phase.
Level Adjust This control adjusts the signal output level of Helios Type 69.
This may be necessary if the signal is dramatically boosted or
reduced by the EQ settings. The available range is –20dB to
+10dB.
