Re: Another First Grapher Needs Help


Good to hear from you Wayne. Neither changing the phase nor distance helped with the 72hz dip. Fooling around with either just accentuated the problem or caused others. What did help is I narrowed the filter at 80hz from 24 to 12. The dip is no longer there but now there is a less pominent dip at 62. I will tweak some more and upload another graph soon.

The 50 hz bloat with the mains is still there and increasing the filter at 48hz doesn't seem to help much. It only causes unwanted dips to each side. I am crossed over in the pre/pro at 80hz.

The next time I have some time to kill I will try a hard knee curve and lower the shelf.

Thanks for your input.

Tom
