Introduction got hiss? Get hush! Rocktron provides a new twist on the world famous hush guitar noise reduction with the hush 2x. Essentially a “double hush”, the 2x offers two completely separate channels of hush noise reduction in a single small unit designed to sit right on top of your guitar amp/...

For maximum noise reduction results, place the hush after your distortion and modulation effects (chorus, flanger, phaser, etc.) but before any delay or reverb effects. If you are already comfortable rolling back your guitar’s volume pot, simply turn your distortion and other effects in the chain be...

Descriptions continued......... Channel 1 - threshold control determines the minimum input level at which the hush filter and downward expander will begin to operate. Setting this control too high will result in a loss of sustain, as notes will tend to die out much faster than they should. Conversel...

Page 13: Hush Information
Hush information in most applications, the signal from an instrument being played is much louder than the noise level. Therefore, much of the noise is not heard when an instrument is being played. However, when you stop playing or let a note decay, the instrument level drops below the noise level an...
Page 14: Hush Information
Hush information when downward expansion begins, the vca acts like an electronic volume control and gradually begins decreasing the output signal relative to the input signal. For example, if the input signal were to drop below the threshold point by 10db, the output would drop approximately 12db. A...

The variable integrated release (v.I.R.) technol- ogy contained in each hush circuit automatically adjusts the release rate of the expander based on the dynamic decay rate of the incoming signal. If the input signal stops suddenly, downward expan- sion will occur rapidly (similar to a gate). If the ...
