SUPER-X PRO CX3400 User Manual
4.  Installation
Your SUPER-X PRO CX3400 was carefully packed in the factory and the packaging 
was designed to protect the unit from rough handling. Nevertheless, we 
recommend that you carefully examine the packaging and its contents for any 
signs of physical damage, which may have occurred in transit.
◊ 
If the unit is damaged, please do not return it to us, but notify your 
dealer and the shipping company immediately, otherwise claims for 
damage or replacement may not be granted. Shipping claims must 
be made by the consignee.
4.1  Rack mounting
The BEHRINGER SUPER-X PRO fits into one standard 19" rack unit of space. 
Please allow at least an additional 4" depth for the connectors on the back panel.
Be sure that there is enough air space around the unit for cooling and please do 
not place the CX3400 on high-temperature devices such as power amps, etc. to 
avoid overheating.
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.
