PRESET SELECT/FUNCTION SELECT
Use this knob to select the different presets available within the HUSH Ultra. See section titled "SELECTING A PRESET"
for more information on how to select a preset. When in "EDIT MODE" it is used to select the desired "FUNCTION"
(Title Edit, True, Bypass, HUSH, Global, MIDI CTRLINK, Preset Mapping, MIDI Dump/Load, or Global Restore)
to be altered. See section titled "CHANGING PRESET PARAMETERS" in this manual for more information on the
FUNCTION SELECT control
IN/OUT button & LED
This switch allows for the HUSH Ultra to be bypassed when noise reduction is not required. When lit, the LED indicates
that the HUSH Ultra is currently active in the signal path.
DISPLAY window
All of the HUSH Ultra's presets, functions and parameters, will be displayed in this window depending on what is being
selected or adjusted.
STORE/EDIT button
This button is used to STORE any changes you make to presets. It is also used to put the HUSH Ultra into "PRESET
EDIT" Mode. See PRESET EDIT mode later in this manual for more details on this function.
HUSH THRESHOLD/PARAMETER ADJUST
This control sets the point at which the downward expander and dynamic filter begin to operate. When in "EDIT
MODE" this control is used to ADJUST the selected PARAMETER, within the selected FUNCTION. See section titled
"CHANGING PRESET PARAMETERS" in this manual for more information on the PARAMETER ADJUST control.
GATE THRESHOLD/PARAMETER SELECT
This control is used to determine the level at which the gate will begin to operate. As the input signal drops below this
level, the gate will activate and downward expansion will begin. When in "EDIT MODE" this control is used to SELECT
a parameter with the selected FUNCTION to be altered. See section titled "CHANGING PRESET PARAMETERS" in
this manual for more information on the PARAMETER SELECT control.
GATE RELEASE LED
When lit, the Gate Release LED indicates that the input signal has dropped below the level set by the Gate Threshold
control, thus activating the gate and providing additional downward expansion.
REF switch
This switch determines the sensitivity of the HUSH Ultra. When using the HUSH Ultra with professional audio equip-
ment providing a nominal output level +4dB, it is recommended that the "+4dB" setting on the unit as the Threshold
adjustment will allow you to optimize noise reduction for this reference level.
If the "-10" setting is used and the unit is overdriven, the "+4" setting should be used.
**The -10db setting is recommended for all instrument rigs.
