ISP Technologies presents the latest generation in high performance Noise Reduction technology, the DECIMATOR(TM) PRO RACK DUAL CHANNEL NOISE REDUCTION SYSTEM. From the original inventors of the HUSH(R) 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 ¼ 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.

Excellent visual displays are provided. The input level is displayed with a 3 colour 'traffic light' style LED meter. The filter cut-off frequency display has nine LED segments and the expander gain reduction has a five segment LED display. Input Impedance: 20KOHM Output Impedance: Less than 1KOHM Maximum Input Level: +20dbu Dynamic Range: greater than 118db Typical Power Consumption: 350mA THD: Less Than .05% Dimensions: 1.75" H x 19" W x 7" D
