The ISP Technologies Decimator Pro Rack Noise Reduction Processor delivers a revolutionary breakthrough in noise reduction with an unparalleled level of performance. 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 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. ISP Technologies has 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
