SUPER-X PRO CX2310 User Manual
4.  Audio Connections
As a standard, the BEHRINGER SUPER-X PRO CX2310 is equipped with 
electronically servo-balanced inputs and outputs. The circuit design features 
automatic hum suppression for balanced signals and so ensures trouble-free 
operation, even at the highest operating levels. Externally induced mains hum, 
etc. can therefore be effectively suppressed. The automatic servo-function 
recognizes the presence of unbalanced connectors and adjusts the nominal level 
internally to avoid level differences between the input and output signals 
(6-dB correction).

Please ensure that only qualified persons install and operate the 
SUPER-X PRO. During installation and operation the user must have 
sufficient electrical contact to earth. Electrostatic charges might affect
