I don't "need" a schematic for the EP2500 (yet), but I'd sure like to have a copy in case I do manage to break mine. And because it's interesting to see how they've implemented stuff like the protection circuits.

Since I will end up fixing the EP2500 myself, does anyone have I ideas for improvment modifications (other than the trash can)?

Default QSC and Bheringer Manufacture locations

QSC is made and assembled in the USA. In California to be precise. This isformation is avaliable on their website.

Bheringer is made in China along with Tapico/Makie/Loud Technologies.

Every QSC that I have ever had the pleasure of working with has always been loud, proud and sounded awesome.

Every Bheringer I have ever worked with sounded good at low volumes but when the party actually got started that's when they quit.

Tapico is a subsidary of Makie which is a subdisdary of Loud Technoligies, Inc. The SRM450's that they produce in China don't produce the wonderful sound that the ones made in Italy do. They seem to be just as durable though. However, if you are looking for a powered sub, look elsewhere than the SWA1501 and the SWA 1801. They seem to have a defect in the amplifiers on these units that overheat and fry the voice coils in their resident speaker all at the same time. I say this because I have had 9 come from the factory on warranty for each one of each, the SWA1501 and SWA1801, model failed within 2 hours of use. If you want a powered subwoofer or an amplifier that you can depend on, QSC is the best way to go.

So for those of you what want to think that Bheringer and QSC come from the same plant, think again, they DON'T!

That's why when I decide to change my mains, I'll go with the QSC HPR powered series.

It may be so, it may not, certainly what it says on the website (fairly vaguely) doesn't really prove it.

You might try looking at the instruction manual at which is in FOUR languages, yet the safety precautions and explanation of symbols at the back is in FIVE languages, the last being in Kanji, presumably Chinese?.

Rather strange, an 'American made' amplifier having an extra page in Chinese?

I have the schematics for the QSC and The behringer Power amps, and have trace them through the circuitry. Exactly the same! They may or may not be produced in the same factory but they share the same schematic. The Qsc probably has better components. Thats about it!

This assembly is manufactured in China and due to certain lead times, availability at any time may vary.

In November 1999, QSC arranged to partner with an Asian firm to produce a new low-cost series of amplifiers overseas.

How about that, young maiden?

There is probably some QSC salesman around...

This topic has already been discused in some thread, and I think that that pictures of both amplifiers were compared.

If my memory doesn't fail, the Behringer EP series are actually improved versions of the unrealiable RMX design that were released after QSC discontinued RMX. One of the improvements consists in replacing the crappy SMD that the RMX had in the main board by standard through hole parts (it was subject to strong thermal cycles and mechanical stress and very prone to failure)...
