djk thaks for the links. But I can't order a service manual at the qscstore. While my VISA card has a european billing address and QSC only accept US addresses, which I think is a little weird. And i really don't mind paying $15 but they don't give me the chance to do it.

So much said about this international "pro" company.

Most of the times a schematics are enough, but in this case I have to adjust the bias and current limit and there are no values for those on the schematics, I have a good ideer what these values might be, but i like doing it "by the book".


Have a nice day/night everybody

Hi Claus
Pls. send me an email and I will send you what you need but it is a big file more than 3 meg.

 

[Claus]

I have send QSC a email and got a very nice respons. So I hope everything are OK and I will receive the files with post. And I would like to say sorry to QSC for what I wrote in my last posting. They are more serious than I thought.

And if everything goes wrong. I would be glad to accept MGR offer.

Have a sunny day
Claus

Serv man

Hi MGR,

is it possible to get that serv manual also on my email?

I got broken RMX 2450 as a "gift" from my friend - so I'd like to try to fix it...

Thanks a lot!

(yeah... i found that schematics, but I can't believe, that this published version is 100% correct, and on the other hand I'm a little bit curious, what is then in that serv manual... 🙂 )

 

[djk]

What part of the schematic do you think wrong?

 

[jokari]

Hi djk, MGR...

It is just my suspicion... I'm curious, what else is then in some file, which is not public... Of course... price for that Serv man is not so high...

So my suspision was, that this way is straight to the Hell, if the schematics 100% fits on real QSC product -> no problem for those CHINA manufacturers to make their own QSC named slightly modified like Q$C 🙂

PCB design is then just question of CHINA layout skills...

anyway thx to MGR... I'll try to go through and make some random checks for comparison...

 

[Claus]

There are already a copies out there.
The Behringer Ep2500 is very close to the QSC RMX2450
and the Ep1500 is very close to the RMX1450.


Have a nice day.

Curious becasue there doesn't appear to be very much *to* it? There really isn't. Op amp directly feeding a CFP with the "output" node driving the ground side of the load. Rail switch is a simple addition, and that's maybe the only difference between the 2450 and 1450.

 

[djk]

All three of these have the same schematics.

The Tapco has the biggest power supply. The Tapco and Qsc have two fans, the Behringer has one.

 

[wg_ski]

All three of these have the same schematics.

I would venture to guess that there are probably about 15 on the market that share that same schematic. One of these days I might even build an exact copy. Or two.
