Thanks Bill and everyone - TLAH Pro !!!!!!!!!!!!!!!!!!!!

That is what a guy who was here who is a DJ said. (Son of a regular attender, who was visiting.)

Listening with his eyes. Piezos.

Those turned out great (looking). I had my doubts as to how they would fit in visually, but they do bookend the stage very well, and really give it an importance it didn't have before.

[Cjeff]

Many liked the sound, A couple said they sounded 'Hollow" or "tinnie" Maybe I need to break them in more?

Are they pointed directly-at-the-listeners in the vertical plane? A laser pointer taped along the edge of a combination or try square, then swept from side to side will give you a visual idea of the spread those arrays. They could've been off-axis and out of the zone.

No they both would have definitely been in the coverage.

[Cjeff]

Used them today for the first time.
Overall very good comments. Many liked the sound, A couple said they sounded 'Hollow" or "tinnie"

Have they been RTA/EQ'd for the room? If so what some may call 'tinny' is highs that they never heard before.

We EQ'd them using the feedback procedure as outlined here.

I do not think so. He thought that they just needed breaking in. Suggested playing music and turning up the bass.

Do not use that procedure. It does nothing to actually adjust the system response to the room. It does set response to control feedback, but that's not the same thing. That sort of adjustment is OK with monitors, where maximum levels are desired and quality of response is secondary, but not mains.

I seem to need a little guidance on setting the EQ

Can anyone direct me to a website or explain how to do it.

I have read about using a frequency analyzer, which I can download on the computer, hook up a mic and read the room.
But not sure how to set up the EQ from there.

Thanks guys.

If you have the equipment to scope, give it a shot. If not, play some music through it and tune it by ear. After getting it as close as you can. Hook up a mic with the channel EQ flat and fine tune the vocal range while just talking and/or singing - in a church setting, the vocals are the most used/important of everything that goes through the system. If it sounds good to your ears - trust it. If you aren't sure about your ears, get someone who has done it to come give you a hand - you'll be surprised how much you can learn by just watching someone set it up by ear.

Good luck

That's the way I learned and still the way I do it more often than not, because situations don't afford the opportunity to do testing.
As Klipsch opined " the midrange is where we live" so I work from the center frequencies out, getting that correct first.

My approach as well - 100% by ear. If you're not used to EQing, it may be hard to get the exact sound your after. A good method for training your ear is to pick a band on the EQ, push it all the way up so that you can easily identify the frequency you're adjusting, then pull it all the way down to drop it out, and then slowly bring it back up until it sounds right.

I get that a LOT. Moving the low pass down into the 15-16kHz range to make them sound more like the entry level speakers most are use to normally "fixes" the problem. Then I attempt to educate about what just happened.

[Sydney]

This helps with ear training and frequency ID

Does this method for settng EQ sound good?

From the EQ part of the forum.
http://billfitzmaurice.info/forum/viewt ... 17&t=12189

"I have used this method, and seems to work ok.

I downloaded Bink test CD.

Then i played different frequencies thru system and adjusted eq until all frequencies sound similarly loud.

After that, even some junk piezos sound good.

I hope it is understandable, english is not my language."

Could I use a SPL meter c-weighted to set the frequencies the same?

Wow, I thought more people would eq by rta'ing.

But I'm also one of those that does it by ear. I tried to eq flat but in the end I never really liked it and ended up tweaking it all the time. So now, I just keep the cabs eq'ed flat and then I just eq the system to my liking.

If my ears don't like it, it must not be right. (and even if it is, if I don't like it's still going to get "fixed")

I suppose many have made the same mistake of trusting numbers or a display rather than the ultimate arbiter - the ears.
On page 112 on McCarthy's Sound Design and Optimization is a Perspective story by Dave Revel about "the temptation to draw nice straight lines on a computer screen using any kind of analysis tool."
McCathy details the deficiencies of RTA.( page 360 - 361 ). He categorizes it as an introductory ear/eye training tool, as opposed to a more sophisticated FFT analyzer.
RTA is after all a one-dimensional snapshot, when a movie is needed.
