4.2 Mains connection
Before you connect your SUPER-X PRO to the mains, please make sure that your local voltage
matches the voltage required by the unit! The fuse holder on the female mains connector has 3 triangular
markers, with two of these triangles opposing each other. Your CX3400 is set to the operating voltage printed
next to these markers, and can be set to another voltage by turning the fuse holder by 180°. CAUTION: this
instruction does not apply to export models exclusively designed, e.g. for 115 V operation!
The mains connection of the CX3400 is made by using the enclosed mains cable and a standard IEC
receptacle. It meets all of the international safety certification requirements.

Please make sure that all units have a proper ground connection. For your own safety, never
remove or disable the ground conductor of the unit or of the AC power cable.
4.3 Audio connections
As a standard, the BEHRINGER SUPER-X PRO CX3400 is equipped with electronically servo-balanced
inputs and outputs. The circuit design features automatic hum and noise reduction for balanced signals and
thus allows for trouble-free operation, even at highest operating levels. Externally induced mains hum, etc. will
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 CX3400. During installation
and operation the user must have sufficient electrical contact to earth. Electrostatic charges
might affect the operation of the SUPER-X PRO.
