Overview

The Rocktron Hush Ultra processor's innovative digital stereo noise exterminator provides two channels of the same world-renowned professional noise reduction used for years in thousands and thousands of guitar rigs and recording studios. 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.

When used properly, the Rocktron Hush Ultra is completely transparent (i.e., it should not effect the audio signal-only the noise). The Hush Ultra front panel provides two controls which each manipulate both channels simultaneously. The Hush Threshold control sets the amount of noise reduction required for a given input signal, while the Gate Threshold control provides additional downward expansion when increased. (The Gate Threshold control may also be used by itself, allowing the unit to be used as strictly a downward expander.)

Rocktron's patented Hush noise reduction is a single-ended system that combines the principles of dynamic filtering and low-level downward expansion.

Dynamic filtering is achieved by dynamically-controlling a low-pass filter to open and close the bandwidth of the output signal. The filter bandwidth will only open far enough to pass the highest frequency information in the input signal, thus reducing the noise above it. For example, if the highest frequency present in the input signal is 8kHz, the filter will open to pass up to 8kHz while the noise from 8kHz to 20kHz would be reduced. If a signal with frequency components up to 20kHz appears at the input, the dynamic filter will open to its full extreme (40kHz).

The second half of the Hush process incorporates downward expansion. The low level expander of the Hush system operates like an electronic volume control. The Hush system utilizes a voltage-controlled amplifier (VCA) circuit which can control the gain between the input and the output from unity to 30, 40 or even 50dB of gain reduction. As the input signal level drops below the user preset threshold point, downward expansion begins. It is at this point that the expander acts like an electronic volume control and gradually begins to decrease the output signal level relative to the input signal level.

Great Unit!!

By Dino

Comments about Rocktron HUSH Ultra Rack Guitar Effects Processor MIDI Controllable:

I use Mesa exclusively live and need a trusted, midi-enabled gate for my high gain rig. This thing works perfectly!!! It actually outshines the ISP Pro Rack G. These Hush units have been around for a long time, and there's a reason for that...because they work great! I'm able to set the Hush Ultra to correspond with the other units in my rack, some settings with heavy gate for the staccato djent, other settings with low gate for lead work and infinite sustain, and no gate for clean channel. This works as is expected and works flawlessly. My tech even set up an expression pedal to change the gate settings on the fly if needed. Great unit!

This thing is amazing!

By Maurice Rogerson

from Potlatch, Idaho

Comments about Rocktron HUSH Ultra Rack Guitar Effects Processor MIDI Controllable:

Plenty of user setting storage locations, MIDI control availability (I will need this later with the Line 6 HD Pro too, as I build my guitar rig).
I read quite a few reviews before I sprung for this unit, some good some bad. What I found is that if anyone didn't get what they were looking for from this, they didn't take the time to read the instructions and set it up properly. Once you learn how to use it, it will clean up your rig and leave you wondering why you didn't get one sooner. This is the ultimate noise gate. Stops the noise dead (I have some time based effects that make a lot of noise), and lets the tone flow as intended.
No issues.
Definitely the the most bang for the buck in noise reduction.

Not a IIxC

By Richard Hummel

from NC

Comments about Rocktron HUSH Ultra Rack Guitar Effects Processor MIDI Controllable:

Not a IIxC. Added noise. Just a bad value considering the alternatives.
I am trying to replace an old Hush IIxC. This is nothing like the old IIxC that just worked, you must be very cautious since it is very easy to ADD noise.
Audio is quantized when changing values.

Best noise silencer ever!

By RushFan-D44Eq

from Midwest

Comments about Rocktron HUSH Ultra Rack Guitar Effects Processor MIDI Controllable:

Works great, never had a problem, completely programmable with 128 presets, offers noise suppression and noise gate. Easy to use.
I have been using this unit for nearly 2 years, and it just works great! It allows you to set presets for various amp settings. You can tweak the amount of hush & noise gate for each setting - very little for clean tone, a bit more for a crunchy rhythmn tone, and a lot more for a boosted, way overdriven lead tone - and when you stop playing, silence! I put it in between my pre-amp and my echo/reverb unit, so that way when I stop playing, I can get those trailing echos and no noise! Way cool. I use a MIDI controller to change patches on my pre-amp and synchronized the patches on the Hush Ultra.
I have never had a problem with it, or my previous unit, the Hush Super C that I used for 10 years prior
Worth every penny to silence my favorite tube amp and effects

An amazing help for noise reduction

By Cristi��́n Carrizo

from Santiago, Chile

Comments about Rocktron HUSH Ultra Rack Guitar Effects Processor MIDI Controllable:

I was recording a cuople of song with a members of my band from my ex-school and we were having a lot of troubless to get the "perfect sound" of the guitar, because the guitarist was a 20 year of experience rookie (if you know what I mean), so one of the guys suggested to use the "processor of his best friend". So after a couple of calls, the machine was there. The difference was unexplicable. No more freakin' noice in a instant! So many time waisted traing to teach a pour guitar player i sayd.... And when I note how much was it, let me write this reviw. Hope you enjoy!
