        This DSP is a good product, but it has a serious gap about the Windows SW user guide. The general user guide shows the meaning of the screen choices but there is not any operating guide related how to equalize both left channel and right channel in a different way. I suggest to Dayton to improve the user documentation adding some operating examples.

        I tested this on my 3-way DIY active speakers to act as a crossover and EQ. The software is good and easy to dial in the filters while measuring with REW. The downside is it is quite noisy, adding quite a bit of audible hiss. It was less noticeable on my smaller speakers with passive crossover networks which helped to filter it out but I won't be using it as a DSP solution for my active speakers. I even tried a high quality linear power supply ...
