When using multi way active speakers you should also first correct the run time and phase settings the ULTRADRIVE PRO DCX2496 digital crossover from BEHRINGER gives you all the tools needed for this Only then does the ULTRAGRAPH DIGITAL come into play Background noise such as mains hum as well as extremely narrow band resonance should first be eliminated by using the DEQ1024 also see ch 3 2 1 This should definitely be done before setting up the sound After this editing you have a basic setup now you can do some manual fine tuning if necessary The following is true A linear response curve is not ideal for every application For example when dealing with voice transmission being able to understand the speaker is the most important factor Therefore the response curve should drop away in the bass range since the voice can carry subsonic noise and floor rumble As a rule extremely low and extremely high frequencies are transmitted much weaker It makes no sense to burden a small P A system with frequencies below 50 Hz the only result in addition to the higher power consumption would most likely be expensive repair costs Ik gt Always keep in mind where the physical limitations of your system are Upon setting up your system as accurately as possible to the desired response curve walk around the listening area so you can get an idea what your system sounds like from various positions Don t forget to implement frequen
