DP-26 2-In/6-Out Professional Digital Audio Processor, DSP Loudspeaker Management for Line Array Systems, All-in-One Matrix System with Equalizer, Crossover, Mixer, Effect Processor & Delayer.

Happy with this. I'm toying with upgrading, but I really don't need to!The USB windows interface feels a bit dated, but is functional and easy to navigate. Nice that can send any input to any of the 6 outputs and configure each totally independently. The graphs are good to see exactly how the crossovers and EQ's are affecting the outputs. I had some issues connecting to my laptop with the connection working, then not, then not reconnecting. I connected through a hub and the problems ceased. Only gripes really are the fan and VU LEDs. The fan is not loud, but audible from 10 feet away. And the LEDs are ridiculously bright. I will probably cover with black electrical tape if I keep it.
