But what happens to the mean uggly behringer when doing just simple things like opamp replacement and maybe bypassing some caps?

Is the source of the Behringer sound the NJM op amp?

The phonic with the opamps was much better. From a life instalation i still have a cheapo Behringer MXX laying around What op amps would be good to replace the NJM? The inputstage has 2 non smd transistors.

I’ve done this before Started by StephenGiles Studio A. The last east german desk The Filters have the standard asian darkgreen foil caps I am thinking about OPA I wonder if the source for the plastic behringer sound are just the cheap low power op amps 450 the interna dont looks too bad You can’t really compare two opamps and decide what opamp is best. The non behringer sounds was hearable. Especially the pre amps are surprising November 01, What a circuit does add is as important as doesn’t add.


I realize there’s plenty of stuff out there which sounds better even in stock form.

I wonder if these opampp tl are somehow a special bread Or also just the little fx you get from the usual we mod a neumann attempts? I build a soundraft channelstrip some time ago, at the band practice I tried it on the singers vocals without telling anyone I would need almost to replace all Or are there hidden traps?

I have a MX If by the Behringer sound you mean noisy – and I mean ssshhhh noise sssshh yyy sssshhh and group inputs that suddenly stop working for no paticular reason and a PSU that has blown up twice then yep – thats a sound. Viitalahde Member Kuhmoinen, Finland Posts: It sounds like a Behringer.

February 11, This all under the estimation that the thing is build like a soundcraft This btw is done because regulations oppamp official side No op-amp swaps will give you the sound you’re after. Maybe the RFZ sounds better than all the others?

So back to my behringer question These are the two problems i see with this: I think i should try where i can make the bigges impact on the sound with specific op amps Would replacing of all op opmap and exchange of the powersupply against a heavier one, clear opzmp situation and bring the behringer to an acceptable level? I’m not really an electronics expert but I’ve read enough opamp-swap-threads here to know that swapping opamps isn’t easy and it usually doesn’t do much good.


The smd board of the behringer dont allows many trys A whole new sound? Any good argument can stop me before its too late ;- Thats this is a pretty uneconomical project is clear Started by AudioJohn The Lab. Any opinions regarding what result to expect?

So ideal chips would probably be something which wouldn’t cost 3x what the mixer did if you ended up needing a bulk of 20 or so while still being a sonic step up from the Any senior east german chip developer around here? Or have they done some nasty tricks to reduce noise that kills the sound anway regardless what op amps are doing the job?


That the win is little or even negativ fx occur when changing a working design so drastical is no surprise. Actually i ve another candidate here Some opamps do some things better than other opamps. Some time ago I tested the behringer mx, a mackie cfx and a phonic MRX for a magazine Please dont think that i am crazy
