2. HUSH ULTRA Front Panel 1 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.
3. HUSH ULTRA Rear Panel 1 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". 2 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. 3 CH.
HUSH Ultra Quick Start The HUSH ULTRA default operation settings are: MIDI CHANNEL = OMNI PROGRAM CHANGES = ON PROGRAM MAPPING = OFF HUSH ACTIVE = IN PROGRAMMING PRESETS: 1. Choose preset number by turning the PRESET/FUNCTION SELECT Knob or use Midi Controller. 2. Adjust Hush threshold control to eliminate noise and hiss by turning the HUSH THRESHOLD/PARAMETER SELECT Knob 3.
HUSH & GATE THRESHOLD HUSH THRESHOLD CONTROL The front panel HUSH Threshold control determines the minimum input level at which the HUSH filter and downward expander will begin to operate. Setting this control too high will result in a loss of sustain, as notes will tend to die out much faster than they should. Conversely, when set too low, the expander will close too late (if at all) and the noise floor will remain audible GATE THRESHOLD CONTROL The other half of the HUSH Ultra consists of a noise gate.

HUSH Description When used properly, the HUSH Ultra should be completely transparent (i.e., it should not effect the audio signal—only the noise). To maximize the performance of the HUSH Ultra, it is necessary to understand its front panel controls and how they work together. By understanding how these controls work, it will be easier to correctly set up the HUSH Ultra to suit any application. The HUSH Ultra front panel provides two controls which each manipulate both channels simultaneously.
This means that if a signal is present at the input which consists of primarily bass components, the dynamic filter will reduce mid or high band noise. If no mid or high band information is present, the filter will close down to a pre-set cut-off point of 1kHz (allowing only frequencies of 1kHz and below to pass). However, if the input signal has high frequency components present, the dynamic filter will open fully to pass the signal and eliminate the possibility of a loss of high end frequency response.
Edit Mode Functions and Parameters Descriptions Each HUSH Ultra preset is divided up into individual blocks called "FUNCTIONS" (such as Global, True Bypass, HUSH, Channel Link, Title Edit, MIDI Dump/Load, and Global Restore). Within each function of each configuration is a set of controls which allow you to manipulate various aspects of that function. These controls are called "PARAMETERS." It is the setting of each of the parameters which determines the overall sound/action of each preset.
TITLE EDIT Function TITLE EDIT The Title Edit function allows you to create a unique name for your preset. The Parameter select knob is used to move the cursor. The Parameter adjust knob is used to change the "character" in the title. PARAMETER SELECT = CHARACTER POSITION PARAMETER ADJUST = CHARACTER SELECT IMPORTANT: When you have completed editing the TITLE you must execute STORE before leaving the TITLE EDIT function.
HUSH® Function HUSH I/O The HUSH I/O parameter simply determines whether the HUSH® circuit is active for the current preset. When "IN" is selected the HUSH is active. When "OUT" is selected the HUSH is "OFF". EXP THRESH1 The EXP THRESHOLD (Expander Threshold) parameter determines the level at which downward expansion begins. For example, if the EXP THRESHOLD was set at -20(dB) and the input signal dropped below -20(dB), downward expansion would begin.
GLOBAL Function The parameters provided in this function affect ALL presets (i.e. the settings stored for these parameters are the same for all presets). The PARAMETER SELECT knob will allow you to access these Global parameters: HUSH OFFSET MIDI RX The HUSH OFFSET parameter allows you to globally (all presets) adjust the HUSH ® Expander Threshold. This means that if this parameter is altered from 0(dB) to +3(dB), the Expander Threshold will be 3dB higher for all presets.
GLOBAL Function continued.... 20 GATE THRESH3 GATE THRESHOLD 3 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. Note that this is only used with the MIDI MCC Link is active. EXP THRESH4 EXPANDER THRESHOLD 4 parameter determines the level at which downward expansion begins.
MIDI CTRLINK: For most users using individual presets will cover your needs however there are some power users that may desire to consider the following. If you have a 4 channel amplifier that you can use 4 controllers to change channels you can program 1preset using the MCC LINK. CTRLINK OFF ; Determines whether function is active CC_NUM_A OFF ..
PRESET MAPPING Function PRESET MAPPING The Preset Mapping function allows you to use a MIDI Controller to recall different presets via program changes. MIDI RECEIVED PROGRAM CHANGE number is on the left side of the screen. The PRESET that will be recalled is on the right side of the screen. Note: PRESET MAP in the GLOBAL FUNCTION must be set to ON for mapping to be active.

Operating the HUSH Ultra The HUSH Ultra provides 128 stored presets. PRESET knob or via a MIDI Controller.
SELECTING A PRESET: There are two ways to select a preset on the HUSH Ultra. You can either turn the PRESET knob to the desired preset you wish to recall. The display will show the selected preset number. 1 1 user 1 1. Turn the preset select knob to the desired preset 2 user 2 The second way to select a preset with a MIDI Controller such as the Rocktron MIDI Xchange, MIDI Mate, All Access or All Access LTD.
CHANGING PRESET PARAMETERS STEP 1 - Enter EDIT MODE by pressing the STORE/EDIT button as shown above. When in EDIT MODE the display will show you are in "EDIT MODE" on the top line. ** EDIT MODE ** STEP 2 - To access the first "FUNCTION" to be adjusted, turn the PRESET/FUNCTION SELECT knob. The display will then show: *** GLOBAL *** STEP 3 - To access the first "PARAMETER" to be adjusted, turn the GATE THRESHOLD/PARAMETER SELECT knob.
STORING CHANGED PRESET PARAMETERS STORE CHANGES AT THE SAME PRESET While viewing a function or parameter title, press the STORE button to start the store procedure. The words "STORE AT PRESET" will now be flashing under the changed preset name as shown below. If you would like to store the changes made at the current preset, simply press the STORE/EDIT button again and the changes will be stored. The word "STORED" will flash once and the preset will be stored.
Title Edit Step 1 To begin the Title Edit function, turn the FUNCTION SELECT knob clockwise until the HUSH Ultra displays "TITLE EDIT". ** title edit Step 2 ** Turn the PARAMETER SELECT knob clockwise to initiate the Title Edit mode. Turning this knob will also select the character above the part of the current title to be edited. The letter to be adjusted will have a flashing box over the character selected.
Title Edit continued......: Step 4 To edit the next character in the next position, turn the PARAMETER SELECT knob one step clockwise. The flashing box will move to the next character to be adjusted. (Flashing box) ** title edit 1huUser ** 18 Character to be changed Step 5 After all the characters have been edited as needed, press the STORE button to save the new title to memory. The HUSH Ultra will flash "STORED" briefly. 1hush ultra NOTE: The STORE button must be pressed to save the new title.
PRESET MAPPING Function Step 1 Use FUNCTION SELECT while in EDIT MODE to select the PRESET MAPPING function * PRESET MAPPING* Step 2 Turn the PARAMETER SELECT to enter the MAPPING MODE. * PRESET MAPPING* 1 MAP TO 15 Step 3 Now the PARAMETER SELECT correlates to the MIDI RECEIVED PROGRAM CHANGE number (number on the left side of screen.) The PARAMETER ADJUST selects the PRESET that will be recalled (Number on the right side of the screen) when the received program change is executed.
MIDI DUMP/LOAD Any or all of the HUSH Ultra's presets may be dumped to another HUSH Ultra a sequencer or MIDI utility program using a PC midi interface to create a ( .syx ) file. All the information about the presets you have created will be dumped consisting of parameter values, title characters and controller assignments. When dumping a single preset into another HUSH Ultra, the dumped preset can be loaded into any preset location on the receiving unit.
MIDI DUMP/LOAD continued.....: Step 5 On the transmitting HUSH Ultra, press the STORE button to dump the preset.
MIDI IN The MIDI IN in the HUSH Ultra will allow you to select presets directly from a MIDI controller such as the Rocktron MIDI XChange, MIDI Mate, All Access or All Access LTD. Follow the connection steps in the CONNECTIONS section of this manual. Please note that though the HUSH Ultra has a 7 Pin din connector any standard 5 pin MIDI cord may be used for device connections.
PHANTOM POWER This 2.5mm PIN jack offers the ability to power Rocktron MIDI foot controllers from a 7-pin MIDI cable which connects from the Rocktron MIDI foot controller to the MIDI IN jack on the rear panel of HUSH Ultra. This eliminates the need to find an AC outlet near where the footpedal would be placed during a performance, or the need to run an extension cord out to the footswitch.
