Page 4: Introduction
The HUSH Ultra features True Bypass, an LCD display and programmable presets with MIDI control allowing you to tailor your HUSH settings on individual presets to suit your needs. The HUSH Ultra provides BOTH 1/4” and XLR inputs and outputs, and is easy to setup and easy to use.
Page 5 OPERATING PRECAUTIONS NOTE: IT IS VERY IMPORTANT THAT YOU READ THIS SECTION TO PROVIDE YEARS OF TROUBLE FREE USE. THIS UNIT REQUIRES CARE- FUL HANDLING.

Page 9: Hush & Gate Threshold Controls
GATE THRESHOLD CONTROL The other half of the HUSH Ultra consists of a noise gate. A noise gate completely shuts off the output signal when the input signal level drops below a prescribed threshold level (volume). On the HUSH Ultra, this threshold is determined by the Gate Threshold control on the front panel.

Page 14: Hush Description
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 cor- rectly set up the HUSH Ultra to suit any application.
Page 15 This means that if a signal is present at the input which consists of primar- ily 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).
Page 16: Hush Ultra Edit Mode (Functions & Parameters)
To access these FUNCTIONS and PARAMETERS, you must first enter into the "EDIT MODE." The HUSH Ultra is set up to allow you to first access each function (via the FUNCTION SELECT knob), then the parameter list for each function (via the PARAMETER SELECT knob) and finally the adjustable value for each parameter (via the PARAMETER ADJUST knob).
Page 17: Title Edit Function
Ultra unaffected. When "OFF" is selected the unit is active and True Bypass is off and HUSH is active. TRUE BYPASS uses high quality relays to perform a total bypass of the HUSH ULTRA when us- ing the ¼ jacks.
Page 18: Hush® 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". The EXP THRESHOLD (Expander Threshold) parameter determines the level at THRESH1 which downward expansion begins.
Page 19: Global Function
The PRESET MAP function allows you to globally turn ON/OFF the PRESET MAPPING function. The preset mapping allows the HUSH Ultra to receive a Program Change from a MIDI Controller for one preset, but to actually recall a different preset. See PRESET MAPPING section later in this manual for more detailed information on PRESET MAP- PING.
Page 20 GLOBAL Function continued..GATE THRESHOLD 3 control is used to determine the level at which the gate will GATE THRESH3 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.
Page 21: Midi Ctrlink Function
MCC LINK is desired. When the CTRLINK is on and you are out of the EDIT MODE and you have sent any of the mapped controllers to the Hush Ultra the Hush Threshold and Gate Threshold controls will automatically map to the appropriate selection HUSH_ THRSH_A , B, C or D.
Page 22: Preset Mapping Function
Note: PRESET MAP in the GLOBAL FUNCTION must be set to ON for mapping to be active. MIDI DUMP/LOAD Function This function allows you to dump 1 preset from one HUSH Ultra to a second 1 PR DUMP/LOAD HUSH Ultra or a MIDI sequencer device.

Page 30: Preset Mapping
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. In above example the HUSH ULTRA received a PROGRAM CHANGE from a midi controller for preset 1. The actual preset recalled will be 15! Note: PRESET MAP in the GLOBAL FUNCTION must be set to ON for map- ping to be active.
Page 31: Midi Dump/Load
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.

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. This 7-pin DIN connector must be connected to the MIDI OUT jack of the transmitting MIDI device via a standard MIDI cable, or to the MIDI THRU jack of the preceding MIDI device (if the HUSH Ultra is within a chain of MIDI devices).
