I purchased this for frequency division, equalization and time delay adjustment for my old Apogee Duetta speakers, which are driven by independent amplifier per driver unit. Since this pair of flat panel speakers have large ups and downs in frequency response, only digital signal processing can correct the frequency response. I also adjust the time delay alignment between low and high frequency units to obtain good trangent waveforms. This Behringer digital signal processor does the job very well. I obtained very natural ( not colored ) sound. It’s $300 price tag is a bargain.

Supplementary information: Frequency response and wavform measurements are made by using Protools recorder system with the use of Earthworks audio M30 mesurement microphones. Waveform WAV files were written by using Matlab.

Ultra High-Precision Digital 24-Bit/96 kHz Loudspeaker Management SystemThe ULTRADRIVE PRO DCX2496 is the ultimate digital loudspeaker management system with an unheard-of audio quality and feature list. It is an indispensable tool for the precise set-up of multiple loudspeaker systems or arrays. Installation contractors, live-sound engineers, cinemas/discotheques/concert hall operators will quickly learn to love this model’s rich features. Signals can be split in various ways to assure precise sound by using the optimal frequency range of each loudspeaker. Configure using the device or take advantage of Windows-based editing software. Three analog inputs and six analog. more.
