In light of the recent discussion on digital X-overs, I have stumbled across the following device from Texas Instruments. The TAS3001 Digital Audio Processor. This device can be used for eq'ing, phase correction, and digital crossovers. All that would then be needed are the output DACs. I am in the process of desiging an evaluation system using two of these devices and an easy to program micro. Gotta love free samples. I will post my progress and findings.
