Behringer DEQ2496 Ultra Curve Pro

Bueno, creo que yo mismo encontré parte de la respuesta, extraido directamente del manual del Behringer DSP 8024 Ultracurve:

“TRUE RESPONSE” CHARACTERISTIC

¨The BEHRINGER ULTRA-CURVE PRO differs greatly from conventional graphic equalizers, in its filter concept
and resulting method of operation. Conventional graphic equalizers are, by the physical nature of their design,
subject to strong interaction between adjacent filters, resulting in a difference between the frequency curve
suggested by the fader position, and the real frequency curve achieved. This difference itself varies depending
on the amount of frequency boost or attenuation applied. The same interaction occurs in digital filters, due to
the finite filter slope used. However, digital control allows us to predict these interactions, and—by generating
a compensating value for each affected filter—to compensate for them.

The algorithm necessary to achieve this has been specially developed for the ULTRA-CURVE PRO, making it
a “true response” equalizer. The advantages of this are directly apparent. Formerly, you had to know exactly
what effect a given equalizer setting on your graphic equalizer would really achieve. If you give the
ULTRA-CURVE PRO a particular setting, you can be sure that the resulting frequency curve will reflect the
visual setting of the frequency filters. The ULTRA-CURVE PRO takes the guesswork and indeed the “witchcraft”
out of equalizing. The new control concept of the ULTRA-CURVE PRO does, however, result in it having
characteristics which need to be explained here. Equalizer settings with extreme differences in levels between
adjacent frequency bands require in some cases internal boosting and attenuation of up to 48 dB. Theoretically,
this is quite possible, but can quickly lead to overloading and distortion of individual filters.¨

En cuanto a la conexión ya leí por otro foro que para ecualizar por hardware externo en multicanal necesito obligatoriamente una etapa externa de amplificacion multicanal, al menos eso parece..
