MULTICOM PRO MDX4400
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 MULTICOM PRO, are
exceptional. They boast extreme linearity and very low distortion characteristics. The most important aspect of
the MULTICOM PRO design is a radical VCA implementation which results in outstanding technical specifica-
tion and excellent performance. 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 MULTICOM PRO MDX 4400 uses SMD technology (Surface Mounted Device). These
sub-miniature components known from aerospace technology allow for an extreme packing density, plus the
unit’s reliability could be improved. Additionally, the unit is manufactured under ISO9000 certified management
system.
2.2 Inputs And Outputs
2.2.1 Balanced Inputs And Outputs
As standard, the BEHRINGER MULTICOM 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).
