ULTRALINK PRO MX882
2. THE DESIGN CONCEPT
2.1 High quality components and design
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. The operational amplifiers NJM4580 which are used in the ULTRALINK PRO, are
exceptional. They boast extreme linearity and very low distortion characteristics. To complement this design
the choice of components includes high tolerance resistors and capacitors, detent potentiometers and several
other stringently selected elements.
For the first time, the ULTRALINK PRO MX882 uses SMD technology (Surface Mounted Device). These
sub-miniature components known from aerospace technology allow for an extreme packing density and
improved reliability. Additionally, the unit is manufactured in compliance with a ISO9000 certified management
system.
2.2 Inputs and outputs
2.2.1 Balanced inputs and outputs
As standard, the BEHRINGER ULTRALINK PRO is installed with electronically servo-balanced inputs and
outputs. The new circuit design features automatic hum and noise reduction for balanced signals and thus
allows for trouble-free operation, even at high 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 (correction
6 dB).
3. INSTALLATION
Your BEHRINGER ULTRALINK PRO 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.
3.1 Rack mounting
The BEHRINGER ULTRALINK PRO fits into one standard 19" rack unit of space (1 3/4"). 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 ULTRALINK PRO on high temperature devices such as power
amplifiers etc. to avoid overheating.
3.2 Mains voltage
Before you connect your ULTRALINK 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 ULTRALINK PRO 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!
