NOISE GATE SETTING

 (Noise Gate) 

 
The 

Mpx Module Setup

 / 

Noise Gate

 function allows you to avoid the effects of background noises while the 

input signal presents a lack of high frequencies. The parameter to be set is the 

Noise Gate Threshold

, which 

determines the threshold value below which the dynamic pre-emphasis is automatically excluded. 

 

The Noise Gate Threshold:

 This may be adjusted within a range of –80 to –51dB (1 dB steps).   

The  Noise  Gate  function  can  be  turned  off  if  necessary  by  turning  the  shuttle  counter-clockwise  to  the  Off 

position. 

 

 

 

12.3.7  BYPASS MODE 

 
In 

Processor  ByPass

  mode,  all  the  processing  stages  are  disabled  (AGC  system,  audio  processing  and  pre-

emphasis circuit). It allows you to carry out tests and reference measurements: it is not intended for equipment 

setup or installation use
