Thanks HTPCat, I emailed Mark earlier tonight and he replied right away and is going to send me packing material and a return label and take care of it. Great service. Hopefully I will be up and running soon. Keep you posted.

Once I took it out of the signal chain I got much flatter response including very good response below 20hz.

So if you are using this -- I would recommend you take measurements. Perhaps mine is just defective -- but this thing seems to be junk, and I wouldn't trust it.

It certainly kills the hum -- but also kills your bass response.

I did measure distortion with Omnimic.

I was measuring with REW and a UMM-6. My bass response with the hum filter showed an odd dip around the crossover (80hz) that would come and go, and a steep roll off starting at 40hz. I don't have the charts - but I was down 10 db at 30 hz, 15+ at 20 hz and at the noise floor by 15hz. Without the filter I had 85 db response +/- 3db from 15hz to 80hz (which is pretty normal for my setup with the MVC set at -15 -- which is where I measure).

Again -- maybe my unit is defective.

This is my response. You may need to work on the phase and time alignment of the system. I am not sure without knowing more about your system.
