What would be a reasonable cost solution to EQ?

EQ guys are using on their cabs/systems. A good starting place if you don't have your own RTA.

What would be a reasonable cost solution to EQ?

#1 Post by MissileCrisis »

Goal: I'd like to be able to measure my home theater (mainly subs) response and use my DCX 2496 to apply a couple modest filters to accommodate room issues. I don't have a sound card (i think) that will allow for mic input (unless the laptop 1/8 inch is any good). I believe all I need is a cheap sound card for testing combined with a ECM or radioshack mic/spl meter. Is there a preferred method of doing this? I'd like to follow the buy once cry once philosphy if at all possible because eventually I'd love to EQ the mains as well (so a mic that goes >15k accurately would be a plus).

Imo, get this:

http://www.parts-express.com/pe/showdet ... er=390-801 (which comes with calibration)

and this:

This is close to what I often use and works perfect with REW or similar software..

Looks brilliant, Except the usb/xlr part, did you have any issues with drivers?
I try to stay away from products with known driver issues but as we all know what's a problem for someone never gets noticed by others.

Also, would something like this work in place of it?

I was actually going to post that "this looks promising" and link to the dayton mic.

It appears that there are some instructions on amazon for how to make it work on windows 7. I appreciate the quick response!

*as in the preamp you suggested, i just ordered it but its on backorder so I expect ~ 2 weeks.

It wont work with a proper measurement mic as it doesnt provide phantom power.. I use the Blue ICICLE with my mac and there are no driver problems.. I used it with a windows 7 pc aswell without any hickups..

If you're really serious about the "buy once, cry once" then go here: Rational Acoustics to get all sorts of very nice measurement equipment :)

Considering my budget, your first suggestion is exactly what I need. Thanks again.

Just got the mic/preamp thing. One question, why is it reading ~150 dB and a bunch of hogwash (i think i messed up the calibration levels or something). Any REW resources would be greatly appreciated as that is the program I am determined to learn but as of yet haven't (windows works fine with it).

That would be why.
99% of the time, things that aren't already being done aren't being done because they don't work. The other 1% is split evenly between fools and geniuses.

After messing around with REW, I now know how to use it to eq. Took a while to figure out but now I'm a happy camper.
