12 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 ts 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
certication 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 eectively suppressed. The automatic servo-function
recognizes the presence of unbalanced connectors and adjusts the nominal level
internally to avoid level dierences 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.
