is generic audio dual opamp (see NJM for datasheet). Aside from working at very low voltages (+/- 2V?) there is nothing special. RC Dual Audio Operational Amplifier. Operating Voltage. ±18 V Low Noise Voltage. µVrms (TYP) Wide GBW. 12 MHz (TYP) Low THD. % (TYP). From a life instalation i still have a cheapo Behringer MXX laying around what a all the x in the name want to tell us?.

I am thinking about OPA Especially the pre amps are surprising Some opamps do some things better than other opamps. O;amp 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.
But a real Neuman style summing would need theire activ transformer isolated fader modules Honestly, I think it’s a waste of time. Or are there hidden traps? Regardless the fact that its rather stupid to put that much work in a Behringer product Or have they done some nasty tricks to reduce noise that kills the sound anway regardless what op amps are doing the job?
Behringer denied to give out schematics I wouldn’t put too much work for opxmp that’s going to blow up anyway. Any good argument can stop me before its too late ;- Thats this is a pretty uneconomical project is clear Just paint it red so people don’t think it’s a behringer!
Is the source of the Behringer sound the NJM op amp?
You can’t really compare two opamps and decide what opamp is best. No op-amp swaps will give you the sound you’re after.
Would replacing of all op amps and exchange of the powersupply against a heavier one, clear the situation and bring the behringer to an acceptable level? I’d probably try to find something the 45800 alot easier to mod, with individual channel boards All my friends ask me if the Behringer is allready in the rubishcontainer and cant beliefe that i am thinking about putting work in it The desk has a good layout Actually i ve another candidate here But what happens lpamp the mean uggly behringer when doing just simple things like opamp replacement and maybe bypassing some caps?
Usually the stuff around the opamp will do more for the sound than the opamp itself. Please dont think opxmp i am 45580 June 07, So back to my behringer question I am however interested to see what happens.
Eric Eric’s Audio Repair http: February 11, I think i should try where i can make the bigges impact on the sound with specific op amps The last east german desk The phonic with the opamps was much better.
Started by StephenGiles Studio A. November 01, I’ve done this before The smd board of the behringer dont allows many trys The classic layout of a 24 in 8 desk with 6 aux and 2 semi para midbands I pretty open to any suggestion that point to risks and problems i ve overseen Maybe you can buy an old opsmp used soundcraft desk for the money? Basically the interna dont looks too bad If you just put them 45580 a circuit designed for cheaper opamps you can easilly make a stable circuit oscillate.
The non behringer sounds was hearable. The RFZ desk sounds interesting!
Any senior east german chip developer around here? Started by Nat The Lab. This btw is done because regulations from official side Started by amphibic The Lab. Any opinions regarding what result to expect? I would need almost to replace all I guess without schematics your guess is as good as ours what opamp is best. 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.
A big step forward?
