2-channel design provides superior instrument tracking
The Hum Extractor + Decimator G rack's 2-channel design gives you the power and versatility of the Decimator’s loop gating while still being triggered via the direct output of your guitar. This means you can insert the Hum Extractor + Decimator G rack into, for instance, the effects loop of your amplifier to filter out noise from everything prior to the power amp and speakers — dirt boxes, vintage stomps, and even your tube amp’s preamp section — to absolutely obliterate unwanted noise. This gives the Hum Extractor + Decimator G rack superior instrument tracking for country as well as metal and intense noise reduction for demanding studio applications.
Wide range of controls for maximum configurability
The ISP Technologies Hum Extractor + Decimator G rack includes a wide range of controls that enable you to fine-tune the noise-reduction system to your rig. An Input Gain knob and Input Level meter safeguard against errant signals, while a Loop Clip indicator makes level-matching the Hum Extractor + Decimator G rack to your amplifier and other gear easy. Separate Hum Extractor and Decimator Threshold knobs tailor the amount of processing for each type of noise reduction, while an HX Position switch allows you to choose where you want to place the hum extraction — directly after your guitar or in your effects loop. The Hum Extractor + Decimator G is one of the most advanced noise reduction systems we’ve seen here at Sweetwater. It could easily be the most valuable piece of kit in your rack.
Decimator X technology offers ultra-transparent performance
If you play through a high-gain amp, noise-reduction solutions can be frustrating. Typical noise gates chop off your notes, while more sophisticated digital options can compromise your tone. Thanks to Decimator X technology, the Hum Extractor + Decimator G rack avoids both of these predicaments. It employs vector integration, which supplies you with flawless adaptive release times. The result is smooth releases, regardless of your playing style. Lightning-fast staccatos? No sweat. Sustained legatos? No problem. With the Hum Extractor + Decimator G rack in your rig, you'll hear nothing but silence between your short riffs, and chopped-off sustained phrases will become a thing of the past.
