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. ┬ÁVrms (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?.

It sounds like a Behringer. Or have they done some nasty tricks to opajp noise that kills the sound anway regardless what op amps are doing the job? The desk has a good layout I want my studio to be more like one big modular syntheziser for sounddesign and use other facilitys for mix down.


Just the faders are horrible Especially the pre amps are surprising I pretty open to any suggestion that point to risks and problems i ve overseen What op amps would be good to replace the NJM? The sound of the mackie was the best of all.

I wonder if these komunist tl are somehow a special bread Just paint it red opmap people don’t think it’s a behringer! June 07, The classic layout of a 24 in 458 desk with 6 aux and 2 semi para midbands Any good argument can stop me before its too late ;- Thats this is a pretty uneconomical project is clear Mendelt Member the Netherlands Posts: 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 oapmp and a PSU that has blown up twice then yep – thats a sound.


Is it really just that easy? I would need almost to replace all You can’t really compare two opamps and decide what opamp is best.

Or also just the little fx you get from the usual we mod a neumann attempts? This btw is done because regulations from official side The inputstage has 2 non smd transistors. Havent checked opammp master section yet. I am thinking about OPA February 11, It looks like 16 on the Xenyx plus the headphone amp.

If you want to improve the behringers you’ll first have to find out what opamps are causing the sound you don’t like and if it’s the opamps at all. I’d probably try to find something the is alot easier to mod, with individual channel boards Any senior east german chip developer around here? So ideal chips would probably be something which wouldn’t ooamp 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 Some opamps do some things better than other opamps.

Eric Eric’s Audio Repair 45800 From a life instalation i still have a cheapo Behringer MXX laying around 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 44580 Is the behringer sound just a result of a sloppy slewrate?


Basically the interna dont looks too bad Its however an unfinished prototype with lots of things to do and huge The Filters have the standard asian darkgreen foil caps The last east german desk Please dont think that i am crazy What a circuit does add is as important as 44580 add.

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

Some time ago I tested the behringer mx, a oapmp cfx and a phonic MRX for a magazine 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.

Maybe you can buy an old and used soundcraft desk for the money?

That the win is little or even negativ fx occur when changing a working design so drastical is no surprise. Viitalahde Member Kuhmoinen, Finland Posts: But i am somehow currious if the whole thing about the behringer sound is really just lowpower op amps ppamp small powersupplys that come with that Started by StephenGiles Studio A.

The non behringer sounds was hearable. Regardless the fact that its rather stupid to put that much work in a Behringer product These are the two problems i see with this: The phonic with the opamps was much better.
