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 and the noise becomes 

much more audible.  Setting the THRESHOLD 

controls just above the level of the noise causes the 

HUSH 2X to begin to decrease the output level so 

that the noise is never heard.

The HUSH 2X incorporates the latest 

advancements in HUSH noise reduction 

technology.  HUSH 2X’s discrete threshold control 

circuit utilizes a voltage-controlled amplifier (VCA) 

as a downward expander which can control the 

gain between the input and output of the HUSH 2X 

from unity to over 60dB of gain reduction.  When 

the input signal is above the threshold level set by 

the THRESHOLD control, the VCA will remain at 

unity gain (i.e. the output level will remain equal to 

the input level).  As the amplitude drops below the 

threshold point, downward expansion will begin.
