FRONT PANEL FEATURES

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.

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.

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.

REAR PANEL FEATURES

CH. A (MONO) IN jacks
This XLR and ¼" mono jack provide inputs to the left channel of the HUSH Ultra. Use either the XLR jack or the ¼" jack when connecting, but not both together. When using only one input use the "CH. A (MONO) XLR or ¼" jack". CH. B IN jacks
This XLR and ¼" mono jack provide inputs to the right channel of the HUSH Ultra. Use either the XLR jack or the ¼" jack when connecting, but not both together.

CH. A jacks
This XLR and ¼" mono jack provide the output from the "CH. A (MONO)" channel of the HUSH Ultra.

CH. B jacks
This XLR and ¼" mono jack provide the output from the "CH. B" channel of the HUSH Ultra. Note: When "CH. A" is used as a single signal source, the signal will be present in both the "CH. A" and "CH. B" outputs.

PHANTOM POWER jack
This 2.5mm pin jack accepts power from the 9VAC adapter supplied with a Rocktron foot controller (sold separately).

MIDI IN jack

If plugging into a Rocktron MIDI controller such as the All Access, MIDI Mate or MIDI Xchange, we recommend using the Rocktron RMM900 7-Pin MIDI Cable (sold separately). Pins 6 and 7 supply phantom power to the Rocktron MIDI controller when using the RMM900.
