The auto-eq works by emitting pink noise and measuring it through a microphone. I bought the $50 Behringer mic for this purpose. I then makes a series of adjustments using its 31 band graphic EQ. Although it may measure properly, I prefer the following method (I disable the graphic EQ module and use the Parametric EQ:
I used the Rives Audio Test CD2 with a Radio Shack Sound Level Meter. The Rives Audio CD has a set of corrected tracks that work with this meter. I take the measurements of all the frequencies, and make some initial adjustments with the EQ corresponding to these frequencies. I find this works particularly well to clean up bass modes. I then use my ear to tweak levels to my liking. My preference is to use a shelving filter on the EQ to slightly reduce frequences above 3K or so, and a slightly bumped lower midrange.
Like I mentioned before, I think the Behringer used completely in the digital domain is very transparent, and I cannot tell a difference between it and the RDQ-1. I would imagine (although not confirmed) that the use of the interal DACS would diminish this transparency. I really was not expecting the Behringer to work this well, but as much as I 'wanted' to hear a difference in sound quality (I had a hard time believing the quality/features can be this good for so little money), I cannot as of yet. Although I think I have pretty good ears, others might be able to tell the difference.
I am very curious what other experiences people have had with this unit. If you decide to try it, please report back as to what you think.
