4 ULTRALINK PRO MX882 User Manual

1. Introduction

With the BEHRINGER ULTRALINK PRO you have purchased an ultra-exible

“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 congurations. Be it the distribution of a stereo

signal to several outputs (splitter); the combination of separate signals to

one stereo output (mixer), or the specic level adaption of individual signals

(bueramplier): 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

rst model several years ago. This splitter/mixer is based on many years of

experience and ndings 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 amplier. 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 exible 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 amplier or any

othercombination.

• Keyboard submixer

• Distribution amplier for P.A. systems, discotheques, theatres, churches,

hotels, communication systems, etc.

• Add-on module for mixer channels

• Add-on module for eect 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 ampliers

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 rst 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

certied 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 eectively suppressed. The automatic servo-function recognizes the

presence of unbalanced connectors and adjusts the nominal level internally to

avoid level dierences between the input and output signals (correction 6 dB).
