The open mainframe architecture of the BEHRINGER ULTRA-CURVE PRO with its many audio processing
features allows it to be used in a multitude of different ways. The following examples will give you an idea of the
versatility of the device.
3.1 Using the ULTRA-CURVE PRO as a summing EQ in a P.A.
This will probably be the most common use for the ULTRA-CURVE PRO.

To obtain the best results the following points should be paid close attention to. Experience has shown that,
before beginning to use the equalizer, it is sensible to listen to a variety of music and speech material with
which you are thoroughly familiar, playing these references straight through the system without any correc-
tive EQ. Should any form of distortion, or unwanted effect be noticed, it will most likely be due to overloading or
signal mismatch within the system, which should first be corrected. The importance of loudspeaker positioning
cannot be overemphasized! There is no equalizer available which can compensate for sound which is washed
out, imprecise and unclear due to interference from walls or ceilings. You can achieve DRASTIC improve-
ments in sound quality by careful repositioning of your loudspeakers. In the case of an active system with two,
three or more loudspeakers served by a crossover you must pay particular attention to travel path time differ-
ences and phase coherence between the different components of the system. (The BEHRINGER SUPER X
crossover, with its variable crossover frequency settings, its phase reverse and electronic time path correction
gives you all the tools required to carry out these corrections.)
Once the above points have been attended to, the ULTRA-CURVE PRO may be put to work. By using the
Automatic Measurement Procedure you will quickly get a usable basic EQ setting. Pay particular attention to
the placement of the Reference Microphone. It should be placed in the direct radiation path of the loudspeaker
system and may not be interfered with by anything causing a disturbance in the room acoustic. Placement
behind curtains, less than 3 feet from side or rear walls, or on a balcony is to be avoided, as these positions
inevitably exhibit a colored, false acoustic. Background noise should be at least 6 dB (preferably 10 dB)
below the nominal working level, otherwise it will influence the measurement to the extent that it cannot be
relied upon to proceed with a workable system equalization. Disturbances such as mains hum, or narrow band
resonances may be effectively eliminated with the ULTRA-CURVE PRO's Parametric Filters. They should be
dealt with before proceeding with a measurement. After the automatic measurement has been completed you
have a basic setup, which you should start to finely adjust manually.
