Decimator Pro Rack G

ISP raises the bar on ultimate guitar performance with the new, novel patent pending Decimato™ Pro Rack G.

The Decimator Pro Rack G guitar noise reduction system defines a new standard for excellence in real time noise reduction performance. It 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.

The Decimator Pro Rack G is the only system in the world designed with two channels of single ended noise reduction configured specifically for high gain guitar applications

Allowing one channel to deliver noise reduction for the guitar directly and a second channel to eliminate amplifier gain noise.

Channel one eliminates the 50 or 60 cycle hum, buzz, stage light noise and any other noise picked up directly by the instrument. The Pro Rack 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 Pro Rack G will also solve the typical high gain feedback or squealing

Problems that the high gain guitar player fights. 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 Pro Rack G. By proper setting of the threshold for channel one and channel two you can eliminate this problem for good.

The Decimator Pro Rack G 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 Decimator Pro Rack G 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 patent pending 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 the Decimator Pro Rack G 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 Pro Rack G 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.

Players keep asking how the Pro Rack G works without any required change in the threshold when changing from clean to distort, read on the Pro Rack G has two channels of noise reduction. The guitar plugs directly into the channel 1 input and the level and frequency detectors for both channel 1 and channel 2 measure the direct guitar input signal. This means that changing from a clean sound to a high gain distortion will not affect the signal seen by the detectors. This means that you can use the first Decimator channel to eliminate any noise that the guitar picks up directly like transformer hum, light noise etc. You simply adjust the threshold of channel 1 to eliminate this front end noise. The second channel is inserted into the effects loop of your amplifier, (requires a series effects loop) and this channel will clean up the high gain preamp noise, ground loop hum, and any other noise that you have in this chain. The beauty of its operation is that the second channel is working to clean up this high gain noise but in response to the actual guitar signal, which typically has a much higher dynamic range than what you would see if this channel's detector's were detecting the high gain signal.

Decimator Pro Rack

The latest generation in high performance Noise Reduction technology, the DECIMATOR™ Pro Rack Dual Channel Noise Reduction System.

From the original inventors of the HUSH® noise reduction comes the latest, most advanced, patent pending, state of the art technology in real time noise reduction. The Decimator offers a revolutionary breakthrough in Noise Reduction processing with an unparalleled level of performance. 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.

The Decimator design offers a novel approach to tracking the envelope of the input signal called Time Vector Processing. Due to this novel approach in controlling the expander, the Decimator system will instantly respond to short staccato notes and, at the same time, will provide a very slow ripple free control of long sustained notes. This means that the Decimator noise reduction system is the most transparent and highest performance noise reduction system available. The Decimator Pro Rack uses both dynamic filtering and low-level downward expansion. A Time Vector Processing circuit controls the release response of both the downward expander and dynamic filter.

The input of the Decimator Pro Rack is TRS 1/4 inch balanced to eliminate any common mode noise. Both channels can be used at a -10 or +4dBU reference level. We have also designed the Decimator Pro Rack using high quality studio grade voltage controlled amplifiers for both the dynamic filer and downward expander. This provides dynamic range noise performance of greater than 118db. This translates into the most transparent noise reduction system you've ever heard. The Decimator Pro Rack is extremely easy to use; simply inset the Decimator at the end of your signal chain or, insert the Decimator Pro Rack in the effects loop of your amplifier to clean up the noise present at the amplifier input as well as the noise in the amplifiers pre-amp section. Packaged in a single space 19-inch rack, the Decimator Pro Rack offers the highest possible performance in a single ended noise reduction system, period.

Audition the Decimator today and experience the highest level of performance available in a noise reduction system. The Decimator Pro Rack is available in both a Pro Rack G specifically designed for guitar and instrument applications and a Pro Rack S for Studio and live sound applications.
