Behringer FBQ2496 Feedback Destroyer

[AxelNotHuman]

Is the behringer fbq2496 good for vocal feedback?

I want a anti-Feedback processor for live shows.

[101AOK]

That actually didn't show anything. You would have to have a view meter in the back of the room attached to a MIC to see the volume improvement was working. Saying chk chk and looking at a light shows the viewer nothing my friend. Go to Radio shack, pic up a SPL meter, video the level from the back of the room as you UP the master whilst the unit is cutting out feedback. SHOW the imprved level via the meter. Then return the SPL to R.S. and say you bought the wrong thing LOL YOU should buy it!

yeah alesis quadraverb!!!....awesome 90s machine

[thetruegents]

interesting vid ta for posting. it would be interesting to hear it in a gig setting, to figure out if it cuts feedback frequencies just enough or completely kills them. im guessing the mix might start sounding a bit weird if that's the case.

[glenmann62]

why did,nt it destroy any feedback?

[adamacin34]

Oh Behringer, what will they think of next. I use a Feedback reducer, its called a 1/3 octave EQ.

[coitussnakes]

hey im thinkin about buyin this unit. im using a danelectro talkbox with a marshall stack. i cant get the volume past 1 without horrible feedback. do you think this will work to at least help that?

[jonx2001]

@coitussnakes You should use a gate for that.

the last check was my favorite

i use a lot of gain on my amp for my guitar. and its that fuzzy feedback that i get from the high gain. will that take it away?

thanks

[guitarbootcamp]

No. It's designed mostly for applications that use microphones.

[ZinayH]

@GLP68 ...You need a Direct Box so it can eliminate the static humming sound due to lack of ground! They have a Ground Lift switch! It isolates grounding circuit for hum or buzz elimination

[acrock21]

@GLP68 i do believe they make one for guitar search guitar center or call them and ask

[riverstrat]

Thanks for the video,

I know very little about a "few db's" but that's quite a bit in sound pressure isn't it ?

I have a powered 15" that I use as my pa, could I expect to turn the volume up from where it starts to squal now at about 8 oclock up to 10 oclock or?

Just looking for the broad stroke, just asking if I can possibly go from 2 to 4 or 5 on a 1 to 10 volume knob using a decent fb destroyer.

Thanks !

[guitarbootcamp]

It really depends on the power amp but I would say maybe something like 8 oclock up to 9 oclock. The better way to control feedback is by basic speaker and microphone placement and using quality mics that are more resistant to feedback.

[rockisdead1946]

Thanks for putting this up. I have a question though. I have an acoustic-eletric guitar, and i was looking at a Sabine FBX-SOLO SL820 Digital Feedback Eliminator. Im getting kinda desperate here because theres no way i can play anywhere with this feedback issue. Would you recomend this product? Or would your recomend something else?

Thanks for reading.

[guitarbootcamp]

In think in general the Sabine units are better.  I don't remember the exact reason but I sold this Behringer unit and bought a Sabine.

Don't expect miracles from a feedback eliminator. It can give you a few DB of extra headroom but it won't eliminate feedback.

[wowsah66]

..thanks anyway :)

[wowsah66]

I have band with PA - monitors..was suggested introduce BFD to reduce feedback. I purchased s/h DSP1100 I think one of the forerunners to the 2496 so I'm hoping the principles are the same,everything seems to work "well it all lights up" although the manual may as well be written in chinese! bandwidths and parameters are rocket science to me!! I am a total novice in this area,I can sort of set to PA or SI and store from1-12..but I don't if this is correct.Can you guide me a little.

Thanks B

[guitarbootcamp]

I really don't know much about the DSP100. I also don't own this unit anymore. Sorry I couldn't help.

[wowsah66]

..thanks anyway :)

I have recently purchased the Feedback Destroyer Pro FBQ2469. I got it because I currently have the v-amp pro, also by behringer, for my guitar. I was looking something to eliminate feedback and this was a cost efficient product by a name that I trusted. However, I did not realize that the feedback destroyer wasn't intended specifically for a guitar. Thus, my question is should I reconsider the purchase and go with another product specific to eliminating hum/buzz for a guitar?

[guitarbootcamp]

yeah you should return it. If hum or buzz is your problem you may need something like aIn SP Technologies Decimator. YOu may want to check your grounding to see of you have ground loops. Do you use a lot of gain on your amp?

[Mikexdeath]

I use tons of gain, I go for a really heavy, solid sound because I play heavier songs eg deathmetal/hardcore/metal.

I realized I had used a poor choice in wording. My amp does create a hum/buzz and I do realize that is due to a current going through it. I guess what I should have asked is will my amp ever produce the type of feedback that the feedback destroyer pro eliminates because if it does then I am going to keep this with my rack.

Thanks for the quick response!

I don't think I quite get the question. But's pretty much impossible to set all the frequencies to kill feedback. These units will find the 8-10 most likely frequencies and then dynamicall adust to seek out others. The frequencies can change based on room conditions and position of the mics.

An feedback unit like this can really only get you 6db more gain before feedback. They help but they can't prevent it all. Your best weapon is the how you set up your PA system in the first place.

[djdan201]

it would be great if you could post a tutorial on how to set all the frequencies to kill feedback...

[STUlaBass]

hi dude, I see U already had some filters active before U started the "learn" procedure. How did U manage to find what frequencies to cut? When I press learn no filters are created

[guitarbootcamp]

Before I hit the learn button there are no filters set. After I hit learn you can see that I defined that I wanted 8 single shot filters and the rest to be automatic filters. You can change this number by the wheel.

During my test 7 static filters were set which you can see after I leave the learn mode near the end of the video.

The manual isn't very clear on exactly how this unit works. On the other hand it's very easy to use.

[STUlaBass]

10x ... the manual isn't very clear. cause I don't understand how to set the filters.

now I'll use the wheel to select some single shots filters ( these don't have any settings such as gain, freq, bandw etc ... I just press PEQ and the wheel .. and they are created - is this right?) and then I press learn. after the learn procedure the settings for each filter will be created by de unit ... CORRECT? 10x again dude

[guitarbootcamp]

It's not clear in the video but after I enter learn mode I'm slowly raising the volume of the PA to create feedback. Once thee feedback starts the unit will set a filter for that frequency. I'm saying "check" to help induce the feedback a little sooner.

I wasn't crazy about the autolearn mode. The unit will send out pulse signals to the system and the pulses keep getting louder to initiate feedback. It just didn't seem like a good thing for my speakers.

[byfy]

I see that 8+7 leds are lit and on the unit display only 8 are shown ( 5.8). after U finish the learn mode the 7 leds in the right disapear and the display shows only the first 8 -1 leds.

[byfy]

could U post a little tutorial ? ... I read the book but I didn't understood how it works.
