GATE SECTION 

 

The gate section works independently from the compressor but is designed to  
complement it's functionality.  The gate is not designed to be a “Hard” cut-off gate  
control, but is designed to be an analogue gentle and musical gate that gently drops  
the background noise by -15dB making it less obvious that a gate has been employed. 

 

THRSH Rotary:

  This is the 

Threshold

 control for the gate. Threshold settings:  

From 0 to -40.  

 
Link Switch:

 The N90 can be linked in any multiple you like (up to 8 modules) by  

utilizing Pin 6 of the 500 Series compatible rack. Pin 6 is designated as the 

Stereo  

Link

 Pin. Usually Pin 6 is linked in pairs, or is bussed. Please see your 500 series 

compatible rack manual for information about how to link the pins. 
 
When N90's are linked via Pin 6 it is always the left-most module that takes  
command when the units are in Link mode. The Link switch must be switched down  
for the N90 to be in link mode.  
 

Link Scenario:

  If you have a rack with 8 x N90's installed and Pin 6 is “bussed”  

on channels 1 to 6. with channel 7 and 8 only linked to each other. 
Switching channels 1 to 6 

Link 

Switch

 

down will link the 6 modules together and  

all 6 channels will follow channel 1.   
If you then switch channels 3 and 4 

Link 

Switch up, channels 2, 3, 5 and 6 will  

continue to follow channel 1, but channels 3 and 4 will work completely  
independently. 

 

At all times channel 7 and 8 would operate independently of each other and the  
other channels, or could be linked together by switching both 

Link

 switches down,  

in which case channel 7 would take control of channel 8.
