Feedback destroyer

[Scott Brochu]

My band is in the process of obtaining one of these destroyers. I know it will come with a manual but I respect the craft of the sound people here on this forum.
It is a 2 channel destroyer and we are getting it to get rid of the feedback from the monitors and some of the FOH feedback.

Where should I put this device in the chain of equipment?

Basically any pointers/ things not to do or do/ settings?

Thanks

Step number one is to find the location from which the feedback is coming. If you determine that it is a single mic, insert the destroyer on that channel and let it do its thing. if it's multiple similar (such as all vocals, all drums, etc) mics throughout the system, bus them and insert on the bus. If it's multiple mics on a particular monitor mix, insert into the signal chain on that mix, same for mains, etc.

In other words, put it wherever the problem is. You'll want to ring the system out ahead of time for about 75% of the filters, and let the other 25% float.

Sorry Scott, I replied to this thread but my computer crashes - fortunately I made a copy!

If it's FOH and monitor chain feedback you are trying to get rid of, you are going to struggle with just one destroyer. I take it the FOH is stereo and you have two monitor mixes? That makes four channels, but anyway.

The destroyer needs to go after the EQ in the signal chain. The notches that it tries to apply may be smoothed out by the EQ otherwise. If you use power amps for your monitors, then stick it just before that. On the FOH mix put it in the signal chain of the main inserts of the mixer, if it doesn't have one, again, place it just before the power amp.

You can use the feedback destroyer as an information tool. Use it on the FOH in learn mode and let it ring out the feedback frequencies. Look and the settings and transfer these room mode resonances into your main EQ. Disconnect the destroyer and put it into you monitor signal chain. This can be done very quickly using a patch bay.

Destroyers are just a lazy man's EQ but can be extremely useful. You will often see repeat offending frequencies with your equipment, but they can save you lots of time.

As for the manual, if it is the Behringer model, you will have to read it as it makes no sense!

Thanks Chris,

and ya I know, the manuals suck and for someone like me that does not know a lot about using some.....most of the equipment in line. It's difficult to make sense of some things.

Another reason the digital eq is still sitting in the practice room.

I am going to hook it up to the main board in the practice room and play with it, both the D eq and the new feedback destroyer.

Thanks guys .

OK trying to figure out if I can use the I/O insert under the XLR to plug a 1/4" cord to the destroyer. Do I need a signal out of the destroyer, or is that it?

I think that is patching.

If I do it this way I think I can still use my 31 ban eq.

THe reason I am going with just that mic mix is because the lead singer is always feeding back into his monitors. SO I made Wedge 10's and it still feedbacks (but less).
So I think it is his mic that the signal needs to be so hot.

The destroyer is an a glorified EQ, so you still need an in and an out.

If you are placing it between the desk and the monitor connect the chain:

Desk -> XLR ->
EQ -> XLR ->
Feedback -> XLR ->
Amp -> Speakon ->
Monitor

I'm not trying to be a smart azz, and maybe I'm stating the obvious and you know this, but...

Yes, you need a signal out of the destroyer. If you are using an I/O insert on the board, you have to get one of these insert cables.

If you already knew that, then forget it.

Have nothing patched in so DDUH ya patch cords. Sorry.

If it is vocal mic than I think this will work. If it is the monitors than I got to do his channel for the wedges which I think will go via xlr before the amp? right?

I use the feedback destroyer in the DEQ on monitors and run from board to the DEQ to the amp so you should be fine running yours that way.

I actually run thru the DCX after the DEQ to chop everything below 100 hz out of the monitors, but that's just my setup.
