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.

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).
