Hi all.
I have an old DSP amp that was tuned for my outdoor speakers. It sounds great, but I don't know the actual EQ settings because I no longer have the software to configure the DSP. I am replacing it with a new DSP amp for which I do have the software. I figured that there should be some way to use REW to get my new amp close to the old one.
I went ahead and measured a sweep with both amps using my UMIK-1 and then tried to manually adjust the PEQs on the DSP to match the curves. I got reasonably close, but ran out of EQ channels before I could get a perfect fit (the new amp is a Powersoft 604, which has high- and low-pass filters and five PEQ channels).
I thought that I could use REW's automatic EQ to generate the necessary settings in the same way that a measurement can be auto-EQed to one of the preconfigured targets. But I could not figure out a way to make a target from a measurement curve. Is there another way to do this?
For reference, here is the psychoacoustically smoothed curve from the old amp (note how the EQ suppresses the low end; the speakers are only rated down to 60Hz):
And here is the best I could do by hand on the new amp:
Any suggestions would be appreciated. I can post the EQ settings also if that is useful.
Thanks!
