Hi there:
Do not think about cloning or buying a behringer, the stuff is crap.

Hi Art!
I would never clone such as cheap amp. I was thinking of buying one and cranking up the idle current to fix the crossover distortion problem. But only if it can be done.. ;-)
Feel free to elaborate on the lack of quality of the A500!

A quick google finds the QSC for sale at $429 and the Behringer at $279 (on the same site) - I know which I'd buy!

Hmmm.... Do they buy also their effect pedals from the same Chinese manufacturer Roland buys from?

Hmmm.... I hope employees of Roland, QSC, and other companies are innocent:

I have both the QSC and the Behringer EP amps and can say they are NOT the same.
Close and, the EP is a very nice amp for the money but, it's no QSC.

Excuse me, which models are you referring at ?
I suppose QSC RMX 1450 e Behringer EP 1500.
From what I understand, they are the same design built with different parts (QSC has higher VA trasformer and better quality components. A better amp actually because these components give an important contribution to sound).
Close and, the EP is a very nice amp for the money but, it's no QSC
I believe that the last series of Behringer amps have exceptionally high quality/price ratio.
By the way I own a Behringer A500 that should be a "clone" of the Qsc RMX 850 (?) and also of the Alesis RA300, the latter a amp recommended by the Audio Physiscs speakers designer,
Joachim Gerhard, here

A very valuable advice I believe.


Thanks and kind regards,

beppe

I was referring to the QSC RMX2450 and the "B" EP2500. These are the models we use.

Design is the same... yes. It is not EXACTLY the same amp as someone posted earlier.

I'm not knocking the EP amps. They sound fine and fill the duties of any amp within their price range.


Next time I have a RMX and an EP out of the racks I'll pull the covers and take some pics of the inside of each amp.

Thank you very much Sir for the very valuable information.
Actually I feel that a lot of manufacturers have implemented the very same designs with components of different qualities.
By the way the basic deisgns seem very good indeed.
I can say that the A500, for its price, is a very good amp indeed.
And of course QSC amps are better built with better components and of course placed at a higher cost.
The choice is up to the customer, as usual.
Another brand using same designs is Tapco I think.
Good build quality. If you search this site you will find some 3D talking about Tapco amps.
Thank you very much again.

Kind regards,

beppe

Maybe it would be a case of "cloning the clone" ?
It's a joke, of course.
Kind regards,

Dear Mr Floding,
I am an owner of a A500.
I would be extremely grateful if you will report your results in case you will crank-up the bias.
Nevertheless I read the test report of a magazine and the distortion figures were very good across the whole audio bandwidth up to about 140W on 4 ohm resistive load.
Where did you find of this crossover distortion problem ?
Of course please feel free to e-mail any time.

Thank you very much indeed.
Kind regards,

beppe
