SEPARATE-LINK A/B 

In Separate mode, the SOC 1.1 operates as two completely individual mono channels. 
 
In Link A/B mode, the compressor side chains are linked to provide stereo tracking.  This 
mode is used to prevent the stereo “image” shifting if a loud sound appears only in one 
channel of a stereo mix. For example, if this mode is not selected, a loud floor tom panned 
hard left in a mix may cause the output stereo image to move towards the right as more 
gain reduction occurs in the left channel than the right. 
 

Important Note:

 Unlike some other VCA based compressors, all controls remain 

operational.  You MUST still set up BOTH A and B channel’s controls in Link A/B mode, usually 
with identical settings for stereo program, fine tuned by ear. 
 

 

POWER 

Fairly obvious, turns the SOC 1.1 on or off and a little yellow LED tells you when you’ve done 
this correctly!  Automatic bypass of the unit is initiated when the power is switched off or if the 
mains power is lost.

SOC 1.1.
