So I got my MiniDSP a few days ago. I got the Rev B board with the 2-way + Parametric plug in so I can run my Hertz comps actively with more control than my deck can provide.
Spent a few hours tearing everything apart and putting the MiniDSP inline. What a pile of JUNK!
First, the supplied RCA's are crap, the ends pulled right off.
Second, with my deck (Alpine 9887) pegged and my amp (Arc CXLR-4150) pegged, there was barely any output and the input meter of the DSP was hovering around -50.
I was trying to figure out what the hell was going on when, POOF! The audio just stopped. The computer still had a link to the board, but was no longer registering input signal even though my deck was still playing full bore.
I reset the board, restored the board but nothing, NADA. What a waste of $140.....
Perhaps you got a defective board, have you tried troubleshooting with minidsp to figure it out? Or did you just give up and toss it?
