ISP Decimator technology defines a new standard in real-time noise-reduction performance for high-gain amps.
Channel one eliminates the 50 or 60 cycle hum, buzz, stage light noise and any other noise picked up directly by the instrument. The ProRack 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 ProRackG will also solve the typical high gain feedback or squealing problem 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 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 Decimator 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 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 ProRackG 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.
