Hello all ,
I bought me a MiniDSP 10x10. My main use case is to drive the 2 two way front speakers and the two way center active. I've some filter recomdations with Linkwitz and other filters in series. The MiniDsp 8x8 software allowes 'just' one filter in the crossover section.
So I used the advanced section with the biquad input window. With the recommended spreed sheet it's easy to generate the values. After procces the curve is shown in the window.
However, I have the follow issue. The frequence curve in the software preview windowes showes no kurve if I load a other biquad set. Just a restore to factory values or reset of the config helps. This seems to be a bug in the SW / Plugin. This makes the handling very unconvinient.
Any recommendations or work arounds?
