Putting myself potentially at risk of being excommunicated from The
Church of the Devine Backbeat, I humbly suggest you look over the
Behringer DEQ2496, which can be had for less than $350, includes a
"graphic" EQ, a parametric EQ, a dynamic EQ, feedback suppression both
settable and forgettable (auto <g>) and a functional 31-band RTA, and
some other stuff, too, (I think, but therefore could be wrong).

I recently installed three of these and was quite pleased. I am about to
spec one for a new church system in the nearest town, and will be
getting one to experiment with for my own uses shortly.

It's quite a lot of bangaroo for what's left of the dollar.

That depends what kind of absorption you need and what frequencies are a
problem. And that's why you need to get the F. Alton Everest book.

That Behringer model does indeed seem like a lot of bang for the buck. I
might not use it for this application but I could see myself using it for
other things in the future. Thanks Hank.

I had the prececessor to this unit and it added an
incredible amount of LF noise even set flat. It gathers
dust. Is the newer one better in that regard?

"Sound Studio Construction on a Budget", 1997, is a good start.
Then his earlier "Master Handbook of Acoustics". Both are very
readable. Measure twice, cut once.

Absolutely, this one has no flies on it that I've found yet. Now, when I
get one here I'll beat on it in ways I didn't with the three installed
in a dance studio in Austin TX. While that wasn't a control room type of
listening environment I did listen via the Senn HD280's, and in one room
it's 4 Bag End TA2000's and a D12E sub driven by Crest PL400's. I think
I'd have noticed unacceptable noise.

The units were clean, clear, and very versatile. I also plan to give the
Beri DCX2496 a whirl. Hopefully I'll get enough stuff off of my plate in
the next couple of weeks to get on with subjecting the Beri's to secret
investigations here at the mountain.

Scott certainly is right about first fixing your control room. Get help
from someone in your area with a clue about this. Personally, I don't
think there are many people with a clue in this area. I certainly would
never design my own control room.

And once you've done everything you realistically can with the room, I
certainly would also recommend a nice 31 band like a Klark Teknik and
borrowing/renting a nice analyzer like a Klark Teknik.

Most important is the person doing the tweeking. I hire the guy who did
my control room. I'm usually the one standing at the mix position
moving the mic in a circle while he fiddles about. Really like the eq
curve he goes for on the analyzer. (Top & bottom with a very specific
rolled off.)

My control room needs a tweak around 4 times a year. Remember, your big
speakers' output is not some universal constant. They change over time
with use. I have the room redone at the change of seasons.

Am not talking big changes on the KT eq. But the difference is
strikingly noticeable when the playback is set up right. Very wide
imaging. Nice accurate bottom. Mixes that go out into the world with
very happy clients.

I wouldn't. You can hear why by patching one across your 2-buss. I wouldn't
put anything in my monitor path that I'd be at all hesitant to place in my
program path.

The only analyzer that's ok is one which can separate the sound from the
speaker from that coming from the room. This will correct speaker system
deficiencies only. Coloring the monitors can't reverse room colorations and
only adds to the confusion.

The major studios REALLY learned this one the hard way back in the 1970s.
