ULTRALINK PRO MX882 User Manual
1. Introduction
With the BEHRINGER ULTRALINK PRO you have purchased an ultra-flexible
“problem solver” in signal distribution applications, designed to meet
highest requirements: professional recording, broadcast and television
studios, CD and digital production facilities, etc. Much like an all-in-one tool,
it provides virtually unlimited configurations. Be it the distribution of a stereo
signal to several outputs (splitter); the combination of separate signals to
one stereo output (mixer), or the specific level adaption of individual signals
(buffer amplifier): the ULTRALINK PRO can perform all of these functions
easily - and simultaneously.
Future-oriented BEHRINGER technology
Our ULTRALINK range of devices has been a hit ever since we introduced our
first model several years ago. This splitter/mixer is based on many years of
experience and findings in mixing technology and is used throughout the world
in renowned studios, sound reinforcement systems as well as in broadcast and
television studios.
It was a real challenge to improve the well-known ULTRALINK even further,
and we are proud of our success. Compared to its predecessor models,
the ULTRALINK PRO not only has additional features, but also comes with
dramatically improved functionality. For example, it now has input and output
level meters and balanced in- and outputs.
The architecture of the ULTRALINK PRO
Basically, the unit consists of six mono channels, which can be used either as a
splitter or as a mixer. For instance, a stereo program source can be inserted via
the main input to be subsequently routed to any of the mono channels that are
set to SPLIT mode. Using the individual BALANCE/PAN control, you can—for each
channel—determine the ratio between the left and right main input signals that
are routed to the corresponding output of the channels. Thus, the stereo input
signal coming from the main input section can be distributed selectively among
the six mono output channels.
In MIX mode, the input signals from the respective channel(s) can be mixed at
the stereo main output, with the individual BALANCE/PAN control determining
the signal ratio between the left and right main outputs (pan function). It is of
particular advantage that, in MIX mode, the stereo input signal from the main
input section is alternatively routed to the main outputs. By using this feature a
total of up to 8 single signals can be combined.
In MIX mode, the mono input signals are simultaneously applied to the
respective mono outputs, which permits each channel to be used as an individual
matching amplifier. The LEVEL controls in the corresponding channels enable
the user to adapt the levels at will, with a maximum gain of +15 dB. Levels used
in home-recording can therefore be converted into studio levels (+4 dBu),
and vice versa.
Typical applications
The ULTRALINK PRO MX882 is one of the most flexible systems of its type.
The following applications can be realized:
2 IN/8 OUT splitter, 8 IN/2 OUT mixer, 6 IN/6 OUT matching amplifier or any
other combination.
•
Keyboard submixer
•
Distribution amplifier for P.A. systems, discotheques, theatres, churches,
hotels, communication systems, etc.
•
Add-on module for mixer channels
•
Add-on module for effect and monitor paths
•
Level translator from -10 dBV to +4 dBu etc.
By combining several ULTRALINK PROs you can set up, for instance, a 24-channel
mixer or splitter.

The following operational manual will introduce you to the BEHRINGER
ULTRALINK PRO and its various functions. After reading the manual
carefully, make sure it is always on hand for future reference.
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).
