Catches the noise other units miss!
From the original inventors of the HUSH noise reduction comes advanced, patent pending, state of the art technology in real time noise suppression. The Decimator offers a revolutionary breakthrough in Noise Reduction processing with an unparalleled level of performance. Most noise reduction systems suffer 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 suppression 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 Pro Rack design offers a novel approach to tracking the envelope of the input signal called Time Vector Processing. Due to this 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 an extremely transparent and high performance system.
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 unit is TRS 1/4 inch balanced to eliminate any common mode noise. Both channels can be used at a -10 or +4dBU reference level. The Decimator Pro Rack is also designed 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.
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, it offers the highest possible performance.
