[. . . ] TECHNICAL BACKGROUND 5. 1 Design concept of the ULTRAFEX PRO The BEHRINGER ULTRAFEX PRO. . . The program material will sound lively and natural again. s improves the intelligibility of speech: voices become clearly articulated, text easily intelligible, the transparency of the vocal increases. s provides a distinct sound improvement, particularly for instruments played in a percussive styleslapped guitars or drums will sound incredibly funky. s provides better stereo imaging: the sound becomes more differentiated, speaker setup poses less problems, yet the signal remains fully mono-compatible. s does not require any decoding process, since sound enhancement with the BEHRINGER ULTRAFEX PRO is not created independently of the signal itself, and remains available even during numerous processing or copying stages. Even digital recordings or CD replaying will gain from the use of the BEHRINGER ULTRAFEX PRO. Even with low sound pressure levels, the ULTRAFEX PRO avoids listening fatigue. s finds useful application in Hi-Fi systems by providing better resolution of the sonic image, due to its suitability for the studio and its outstanding specifications. In particular, the processing of old analogue recordings (disks and tapes) proves to be very efficient with the ULTRAFEX PRO. s produces a more powerful and fuller bass which does not sound muddy. All recordings will benefit from the dry and precisely defined bass contouring. s produces an improved spatial enhancement and stereo effect intensity with the surround processor without audibly colouring the sonic image. TECHNICAL BACKGROUND ULTRAFEX PRO EX3200 5. 2 Psycho-acoustic background The term psycho-acoustics refers to the psychological aspect of hearingin contrast to the physiological transfer of impulses (transmission of nervous impulses). Psycho-acoustics examines the effect of sound on the listener and the reasons for certain sonic impressions. How a sound is interpreted is influenced by a lot of factors, most of them can hardly be measured yet are fairly important. For instance, those portions which are responsible for the spatial localization of a sound. Nevertheless, they determine the quality of a recording to an extraordinarily large extent. There are also portions of the audio spectrum which we perceive as presence or naturalness. If this kind of information is missing, the recording suffers from a loss in freshness, liveliness and spatial transparency. Furthermore, natural harmonics are essential components of the sound. Often enough, they only represent a minor portion of the signal and are easily lost. [. . . ] This also applies to defects caused by normal wear and tear, in particular, of faders, potentiometers, keys/buttons and similar parts. Damages/defects caused by the following conditions are not covered by this warranty: s misuse, neglect or failure to operate the unit in compliance with the instructions given in BEHRINGER user or service manuals. s connection or operation of the unit in any way that does not comply with the technical or safety regulations applicable in the country where the product is used. s damages/defects caused by force majeure or any other condition that is beyond the control of BEHRINGER.
