I now have supper flat input signals coming in... I had to take my input signal Pre BOSE amplifier to get a flat'sh full range signal. The downside is that my variable voltage starts at <200 mv and at half volume i have 1 volt of output and at max volume 2.5 volts clean. So i am looking at using an Overdriver of some type to feed the DSP, currently using an AudioControl LC6i
