Headworn AT892c settings Suggests ???

[EvertonMc VinoN]

My church recently bought an AT892c, it's our frist time with a Omni Headworn,
A lot of feedback! maybe un-experiences reason.
we are using it with a Sennheiser Evolution wireless bodypack...
Can anybody help me how to set my system, EQ's...
Surely you have some suggests for me,
Thanks in advance,

For what purpose are you using the headworn?
Because of the omni pickup pattern, it is not recommended that it be folded back through floor wedges.
Can you explain how you are using it?

Are you sure it's feedback? Or could it be clipping (over modulation) and a problem with the sensitivity being set to high? You'll probably need to adjust the transmitter sensitivity factory preset down to -20db or -30db. I've found on my new G2's I have to set the transmitter sensitivity to -20db for spoken word applications or they'll clip easily (you might also have to adjust the receiver's audio output...pg. 33). See pages 32-33 in the Sennheiser Evolution PDF User Guide for setting transmitter sensitivity. If you have a G2 100-500 Evolution series the transmitter sensitivity should set pretty much the same way. To learn how to navigate the transmitter operating menu see pages 25-26 in the PDF guide.

i am using it for speaker/pastor app, the sanctuary is (maybe the problem) placed on a corner of the room. Actually i've tested the system on anothers enviroments having the same response.

Do you know about if it is necessary to apply some specific Dynamics to get a well response for this applications (condenser omni headworn).

Thanks in advance for the posts

ThankU very much for your post,
The sensitivity is already adjusted to -30dB and AFOut (output gain) to 0dB, no problems with that.

Inserting a Graph EQ through mic's channel i've made the maverlous of no feedbacks, but the frequency response was widely killed. And pastors got a limited mobility field...

If you turn on your TV you can see others preachers using the same mic, with a perfect frequency response and extreme mobility. It has to be something else i am not setting well on the system or the mixer.

Where are your speakers in relationship to where your pastor gives his sermon?

i did a layout but i still cant post images.

please visit: www . ccivinonuevo . org /images/layoutVN.jpg

Blue: PA Speakers
Green: Stage Monitors
Red: Pastor
Gray: Fellowship

This is our house of worship, 300ppl , on the other hand, at novembre we'll be moving to a bigger one... diferent shape, more like a rectangle... but designed with curves and others acoustic treatments.

Thanks for your help

Just a couple of more things. Do you turn the pastor's mic up in any floor monitors? Also, could you describe the tone of the feedback?

[EvertonMc VinoN]

yes, but with floor monitors turned off is still hard to equalize.
like i told before, i have to "kill" a lot of freq's to destroy multiple feedbacks and the freq response loses too many quality.
Do u think that inserting dynamics (gate/comp) can help to solve the problem?
Any experience inserting dyn's to headworn condenser mic's?

[tootallll]

Here's your layout...

[cmchamp]

No, dynamics processing such as a gate will help. A compressor will reduce the peaks if your pastor is a very dynamic speaker, but will do nothing for feedback.
You don't have the pastors bodypack and another handheld on the same frequency, do you?
The only other thing I can think of is that being dead center between two loudspeakers, if they are 12" or less LF drivers, anything below, say 800Hz could be causing the trouble.

[[Director] drew ryan]

I was just thinking that if your feedback seems to be in the lower frequencies that you could hi pass the channel up to about 150 before you would notice any difference in your frequency response and then use a parametric eq to tame some of the other squeels.
