DUALFEX PRO EX2200
1. INTRODUCTION
In purchasing the new DUALFEX PRO Model EX2200, you have acquired an extremely efficient and universal sound enhancement processor. The sound precision and flexibility of the functions are the main outstanding features of this high-end unit. The DUALFEX PRO is one of our state-of-the-art sound enhancement systems offering a special combination of sound improvement designs. The unit can be used wherever professional sound improvement is required. The BEHRINGER DUALFEX PRO is the no-compromise answer when the situation demands a no-compromise solution.
+The following operational manual will introduce you to the BEHRINGER DUALFEX PRO and its various functions. After reading the manual carefully, make sure it is always on hand for future reference.
1.1 The Design Concept
Since its announcement of the first DUALFEX model in year 1990, it has caused a sensation. This high-end sound enhancement processor is based on our many years of experience and discoveries in the field of psycho-acoustics. The DUALFEX PRO finds widespread application throughout the world, in renowned studios, sound reinforcement systems as well as in broadcast and TV studios.
The task to improve our famous DUALFEX PRO II was a big challenge. We are very proud that we succeeded. Compared to its predecessors, the DUALFEX PRO offers several advanced features and we have succeeded in dramatically refining the audio qualities. The unit now features a “Mode” function which enables you to select either a soft and warm bass sound or a super-tight bass. Beside that a new VSP circuitry (Variable Sound Processing) has been added to allow you to use simultaneous exciter and enhancer sound processing.
Since the introduction of the first psycho-acoustic processors, technology in this field has made tremendous progress. Although the fundamental principles of enhancer and exciter technology have been well-known for a long time, engineers have been able to refine and improve the essential components over and over again. The BEHRINGER company has also contributed considerably to this development:
With the introduction of our Natural Sonic processor, we have set new standards. Previously encountered problems of restricted leveling range, plus increased noise level and audible distortion during signal processing, are typical shortcomings of conventional circuit designs. They were completely solved by the development of our new circuitry.
Sophisticated manufacturing and quality assurance system
For the first time, the DUALFEX PRO EX2200 uses SMD technology (Surface Mounted Device). These sub-miniature components known from aerospace technology allow for an extreme packing density, plus improve the unit´s reliability.
The BEHRINGER Natural Sonic Processor: Sound enhancement of classical and pop music
The BEHRINGER Natural Sonic principle is based on frequency-selective phase shifting in conjunction with program-dependent equalization and pulse enlargement. An automatic and natural correction during signal processing offers a quality of sound enhancement that has been almost inconceivable until now. Programdependent control permits the “musical” and unobtrusive transparency required for classical music material, yet also provides the necessary brilliance for pop recordings. Owing to its dynamic control and in contrast with conventional units, the circuitry does NOT introduce any additional noise, non-related harmonics or distortion.
The VSP (Variable Sound Processing) circuit
The new VSP (Variable Sound Processing) circuit used for the first time in the DUALFEX PRO, allows for variably fading over from enhancer to exciter mode. Using the PROCESS control clockwise, the exciter circuit comes in additionally to provide a variable and carefully adjusted processing of high frequencies. The result is an increased brilliance and transparency. Fading over from one effect to the other can thus adapt the effects perfectly to the respective program material.
Bass processor
The DUALFEX PRO is equipped with a separate bass processor which allows for sound enhancement in the lower frequency band. A newly developed “Dual Mode” circuit allows you to vary between two different bass sounds from “soft” to “tight”. Processing the bass range means an optimum completion of high-frequency processing and opens up new dimensions in the field of sound processing.
