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.
