I have tried everything I can think of. Minidsp forum is down right now. I'm using it to run 4 subs 1 Input. The model is minidsp flex with dirac live. I set subs crossover at 80hz low pass. I have all output getting signal from dirac 1. Avr is a anthem avm70. When I go into dirac calibration u can really hear the subs but dirac has a problem says low signal to noise floor. So I gave up on that problem for now but shouldn't I still get sub output when I turn up the gains? I got some screen shots also. Should i use the direc option with the flex for subs or just turn it off?
