Learning about home and pro audio

[oyo]

Hello, all!

I came in from a link at Head-Fi headphone board after seeing a dicussion on sub eq-ing.

The Room EQ Wizard caught my attention, since I have been working on the eq by ear in a large room with a tri-amped PA system with a set of Rane RPM88's as speaker controllers. I thought I would see how well it would translate over from home theater audio.

I'm sure it will help at home on a 5.1 system too, what with my miss-matched mishmash of 70's 80's and 90's components.

Good, clear punchy sound is my goal, no matter whether it is pro or home audio and no matter what the age of the components...

Hi oyo and welcome to the Shack!

I'm sure you'll like REW and glad you found your way over...

Thanks for making REW available from the forum. The program appears to be the ideal set-up tool for both home theater and pro audio uses. It has many advanced features that go beyond your average real time analyzer.

Any plans to include TEF analysis? REW is already awesome, adding the ability to "see" reflected, delayed sound would rock!

I have been lurking and learning today- great info here. I can't wait to test the room response, at home, work and church.

Home- My Boston Acoustics sub shakes the house OK on movies, but sounds unnatural on CD playback.
Work- a bizarre permanent installation sets up a bizarre standing wave problem that probably can't be EQ'd away.
Church- A real high tech system that should sound much better than it does. I've tuned it about as well as I can without measurement tools, (other than my ears). Thanks to REW and my trusty RatShack SPL meter I can now see where the problems are...

Hey Oyo
welcome to the shack, pro audio has been an interest of mine as well

I wish I had stuff worthy of Rane EQ's owell...

The good stuff is not at my house- I'd have a tough time to justify even a used BFD there.

Real Life Family Center, ( http://www.reallifefamilycenter.com/) the church I go, to just bought a newly remodeled building from another congregation that felt the call to move downtown.

The other church had top-of-the-line gear sold to them, including an overpriced (for the application) high end HT surround processor and 3 home audio amps, as well as 9 QSC commercial amps. They put in FOUR Rane RPM 88's that do compression, limiting, distribution, automixing, crossovers, and other tasks. The problem is that the contractor sold the previous tenants a lot of gear and (mostly) installed it, then went out of business without setting any of it up well.

When I visited one of their services before they moved, they had a lovely "wall of mud" kind of vibe in their sound. Upon inspection after we moved in the subs ( were crossed over at 120 Hz while the mains were crossed at 80. This, combined with room resonance modes made for low intelligibility and low end feedback/ring modes in the room.

I was able to tame a lot of that by just resetting the crossover to 90Hz on the subs and mains, and have since been working with the delays to time align the system, and to EQ the room by ear.

REW should be a big help, but I'm thinking I should also buy one of the Behringer measurement mics, rather than using my RS digital SPL meter's mic. From lurking a bit, I've seen that the SPL meter mics are OK for setting subs but not so accurate for whole system. I'd like to run a sweep or eight to see what the real response is for each part of the system.

Any advice, or should I take this to another thread at this point?

Thanks.
