In this third video we discuss our ATE process, which is one of the final quality assurance tests that all iTech amplifiers go through before being sent to customers. Note the printout of the 'Test Passed' receipt at the end, it's our way of showing customers that their amp was tested to spec and passed before being sent out into the world!

I fix amplifier for many years and is true, new Crown amplifiers are not the best, but this is a problem for all companies. I fix Audio Research high End audio too, they are still in USA. Cheers.

I bought two Crown XTi 1002 for subwoofer duty. The subs were 5ohm minimum on each channel. The amps seemed to not deliver below 25Hz.

qsc rmxa series will laugh at 10hz, especially the 4050a or 2450a running 2 ohms per channel or 4 ohms bridged.

Quero deixar registrado que a união da Crown e JBL ficou excelente, potencia e qualidade, sendo que a energia eletrica do Brazil não é das melhores sendo assim o uso em 110Vts causa problemas, mais em 220Vts é perfeito, obrigado por suas qualidades!!!

i need some technical info about how we can test the crown dci amplifier power supply if the amp does power on with green light but doesn't fully power on with blue light (dci-n series). we are authorized dealers of JBL in our region. (rt@ncsp.pk) kindly reply.

Love this video but now crown amplifiers are a little bit snow flaky besides the crown xti6002 and up and surprisingly the xls series is solid to but other than that I’ve seen so many amps fail and it’s all because crown products are now being made in China instead of the United States, have 2 crown xls1500 both on bridge mono mode running 2 jbl sr4718x per side and I have to be honest those small things pack suck a big punch, I’ve abused the amp for 8 years now and the thing has never overheated or shut off on me ever big plus for me because it’s light weight, powerful and the power consumption is not much at all!

As technology advances, other problems arise. Switched power supplies with pfc and class d circuits are excellent combinations, it's a pity that even so....they burn! I don't care about very low levels of thd, Slew reat, imd,... I'm interested in an amplifier that doesn't burn!

Here's the deal with Crown. China is not the issue Harmon international is . They gobbled up some of the top pro manufacturers then decided to make products at a price point for everyone . Crown was never intended to be a product for every one it was for those who were "ready for real".. real power ,real reliability, real high fidelity and yes real pro sound. Crown is not for the hands of the local joe dirt grunge garage band. Stop building for the masses and build for the real pros who care about abd respect their profession and equipment.

"Passed all test"....but no actual performance numbers given. Wonder why? Because even Crown knows that they are sending out misleading information on power output!
@michaelbauers8800
@michaelbauers8800 6 лет назад
Have you seen results from testing, out of curiosity? Power measurements don't really seem to be done to FTC rules anymore. But in theory, after a warmup, the amp needs to deliver the stated power into 2 channels, for a period of time without failing, etc. Just not sure anyone bothers anymore.
