OVERVIEW

ISP Decimator technology defines a new standard in real-time noise-reduction performance for high-gain amps.

The Decimator ProRackG guitar noise reduction system establishes a new standard for excellence in real time noise suppression performance. The Decimator ProRackG was designed to provide the maximum possible performance in a rack mount dual channel noise reduction system designed specifically for extremely high gain guitar amplifiers. Designed with 2 channels of single ended noise reduction configured specifically for high gain guitar applications, it allows one channel to deliver noise reduction for the guitar directly and a second channel to eliminate amplifier gain noise.

Channel one eliminates 50 or 60 cycle hum, buzz, stage light noise and any other noise picked up directly by the instrument. The ProRackG channel one output drives the front end of your guitar amplifier and eliminates all of the input noise picked up by the guitar. The control circuit of the second channel detects and tracks the guitar signal directly while the signal processing audio chain is patched into the effects loop of the high gain guitar amplifier. Now you can quiet down even the most insane amounts of noise with any amplifier system incorporating a series effects loop. The Decimator unit will also solve the typical high gain feedback or squealing problem high gain guitar players fight.

You know how difficult this problem can be. You play staccato notes and in between each note you have a squeal or burst of feedback that's virtually impossible to control. Problem solved with the Decimator ProRackG. By proper setting of the threshold for channel one and channel two you can eliminate this problem for good.

The Decimator ProRackG has dual processing channels incorporating both low-level downward expansion and dynamically controlled low-pass filtering in a very easy to use single rack space unit. The ProRackG is based on ISP Technologies patent pending "Time Vector Processing," which provides the most adaptively dynamic release response characteristics of any real time noise reduction system. The Time Vector Processing dynamic response circuit is used to control the release time constant of both the downward expander and dynamic filter. Not only does it deliver the most stunning noise reduction, it also solves the problem of needing to adjust the Threshold setting every time you change gain or switch channels.

By using the input guitar signal to drive both channels' level detection circuitry, the ProRackG needs no other adjustments once the thresholds are set based on the guitar input. This will give you the correct threshold with clean, crunch and even monstrous amounts of gain and if you use pedals you can insert them in the loop between the output of the Decimator Channel 1 and the input of the guitar amplifier.


Banish noise from your performances. Put it in the cart!

this thing is amazing! all noise is gone as long as its in a serial effect loop. i cannot play without it, everyone wants to borrow it for recording and gigs, it can be formated easily into any rig. isp answers the phone and gives great support and advice, they fixed the unit when i messed up a jack disconnecting in the dark. my only suggestion would be to put a input on the front in addition to the one on the rear for those of us that don't use wireless units or additional output to feed a tuner so its no in line with the signal. in the end this thing is amazing, cannot recommend it highly enough,every high gain player needs this or the pedal version.. i can now blast my engl rack setup full volume have controlled feedback and take my hands off the strings and play naturally with full confidence that i want have squeals or buzz.

    Comments about ISP Technologies Decimator ProRack G Noise Reduction System:

    I was tired of high-gain noise of my Mesa/Boogie Triaxis (LD1 Red channel, Rectifier; used with TS808 drive) and dialing gain down or changing channel to get rid of its 'hsssshhh' noise that comes every time you stop playing. I put this noise gate into a chain, played with settings for about a half an hour and it IS silent now. I'm impressed by the way it works and I can hardly believe I will never get that annoying noise back! It looks like it does not affect the sound too, killing noise only.

    Absolutely recommended unit, it's worth the money that I've paid for it.

        Comments about ISP Technologies Decimator ProRack G Noise Reduction System:

        Do not believe the reviewers who tell you the HUSH system is superior or equal. They are likely employees, fools, or ignorant. The HUSH system, as well as all other noise reduction systems suffers from one major problem inherent in their design: The system cannot be immediately responsive to both very short-term staccato notes and long slowly decaying signals. The typical downward expander noise reduction system suffers from a dead zone in the release response characteristic, which causes a compromise in tracking both fast decaying notes and long sustained notes. This works. Buy it now.

        Comments about ISP Technologies Decimator ProRack G Noise Reduction System:

        If you are looking for a noise gate that doesn't hurt your sound this is the only choice. The people that don't have any luck with it just simply aren't hooking it up right. If you follow the diagram that the manual gives you all it takes is a little playing around with and it'll work perfectly. I'm using an orange rockerverb 100 and a delay pedal and the noise gate does what it should without ruining tone or anything. Well worth the chunck of change!

                Comments about ISP Technologies Decimator ProRack G Noise Reduction System:

                I've had this unit now for approx. 2 years. It's a solid unit. I would recommend it to anyone looking for a noise suppression unit. I use it in conjunction with my Marshall JVM unit. No matter what configuration I set it up with. This unit always comes through and provides the silence when I need it. Although the price may scare some away. It's still, in my opinion, a much better way to go than the pedal (dual channel).

                The mother of noise reduction

                By 

                from SF, CA

                Comments about ISP Technologies Decimator ProRack G Noise Reduction System:

                I'll keep this simple because this unit does a simple job. Kills noise. It does it better than anything I've ever used. Even with a 5150 and a distortion pedal, it totally kills all the noise and can somehow tell what noise is wanted or unwanted. I can let a note ring forever and it glides out slowly and gracefully as if no noise reduction is even there. High speed staccato with globs of distortion? It is DEAD silent in between the notes, I can't believe how fast this thing reacts. I've jammed with the hush pedal, boss noise pedals, I've used Engl Powerballs with their built in "high end" noise reduction and none of them hold a candle to this thing. If you want to kill your noise, no matter your style just suck it up and buy this thing. Expensive? Yes. Worth it? YES.

                Comments about ISP Technologies Decimator ProRack G Noise Reduction System:

                Just got this item today. And let me tell you this was well worth the money. Been after that "Master of Puppets" crunch from my Mesa Boogie Mark iiC+ and now I have found the missing link. I was skeptical and the price did scare me, but now I have no idea how I got by without one. A must have and quite easy to use. If you have any question Bill at ISP will help dial you in.
