Sounds like a ground looping issue and it is probably over exaggerated by the gain staging you're using. If possible you want to have all gains at 0db before the amp. If your signal is not peaking at 0db with that then you can turn something up but you should do it as early on in the signal chain as possible. The noise issue should be quieter and you'll have a nicer sounding system. If the noise is still too loud look for a ground lift switch on one of your components. If you can't find one unplug one component at a time till the noise stops and then disconnect that components ground. Only do the last one if it's a low amp component though cause of safety.
My audio interface has something called a "Ground Lift". This eliminates that kind of hum on balanced cables (XLR and TRS). I don't know if your EQ has that option though.
Its more likely cause by the main psu caps due to use ,just replace them and the problem is going to be out Also you could check to see if the hum is present when nothing is connected to the input on the eq with the exact same settins i bet that the hum is still gonna be there cause its not a fault of the wiring otherwise you cables are picking up hum
Ok I use same model as u the FBQ3102 and also even the smaller one FBQ1502. Not sure if it helps but try using fully XLRs I changed from 1/4s to XLR help me reduce that floor noise or whatever u call it :) Hope this helps :)
You need to replace the caps as someone said down below, they filter out noise from your mains. but if it is a ground loop you can test this by running an extension cord from another power point thats on a different circuit breaker. but it's not a ground loop as the feedback destroyer would cancel it out unless that circuitry is faulty an by getting power from a different circuit you will know if it still humms its your caps, if it fixes the problem then the feedback destroyer circuitry is bad also just keep in mind if your avr doesn't have balanced outputs from the start then its possible your picking up noise at the start of the signal chain
just solder your audio ground point to the grounded area of the amp and it dose not matter if they are connected right because signal wires are just R+ and L- and GROUND wire so just SOLDER the GROUND WIRE to a grounded area
it can be the use of power sockets. if you have the one EQ connected to a power socket with mange connections it is perhaps what creates the problem of the sound. Try to connect it right to the wall.
This is the problem with buying budget/entry level gear like Behringer... to stay cost competitive they have to cut corners. The sliders on these units are cheap and scratchy compared to DBX; the build quality is also not consistent - there is another video on RU-vid of a guy unboxing a new unit and the edge of the front panel has a small dent in it... This noise is caused by a ground loop somewhere in the unit or a poor solder joint. I'd return it and spend the extra bucks and buy a better unit.
Are you sure it's not a ground looping error? I've seen repairs by soldering the case to the inputs outside casing... might not work on this amplifier.
hey man how u doin i am an audio buff myself i recently got a new pair of JBL everest elite headphones and they sound good what headphones do u use man?
