QSC assembles the RMX and GQX Series in Singapore, Malasya and those Phonic amps are manufactured in Shenzhen, China.
 
Given the fact that the QSC RMX Series power output architecture has very little differences with their earlier-ancient Series One amplifiers, I could think that these recent Phonic/Crown devices are product of Chinese infamous Inverse Engineering procedure. I'd like to think that Crown bought and endorsed these power amplifiers as XLS & P.L.S Series in effort to launch a very affordable level entry solution to their market just to keep their boat floating through this world economic crisis and they never took further previsions of patents or copyrights. I just cannot  imagine Harman Group or Crown's General Management taking the risk of violating Intellectual Property Rights to earn an additional couple of bucks, mostly when QSC Audio is located inside USA where zillionaire lawsuits are the house specialty.
 
As entry level amps are subject of piracy policies, there are other high tech, high profile and very expensive amps cloned too. In this same thread I could see some fake Lab.gruppen devices which exhibit clearly the same components in the same layout but costs just 600€ if you buy 10 pieces. The only thing they couldn't afford was Lab.gruppen's proprietary NomadLink monitor hardware cause it clearly would imply some internal collaboration and I'm pretty sure that's not the case.
 
Meanwhile, people around the world buy those Asian clones regardless the procedence of their designs whilst original manufacturers are investing valuable resources to keep their business running on. Do you imagine the Camco or Electro Voice Logo in the front plate of these "original" amplifiers? Would you buy them? Yeah, I thought the same way.
 
Ouch
 


you may be right, but some time ago one of the users from my forum posted this link:
http://doc.phonic.com/file/browse.php?sess=&parent=1180&expand=&order=name&curview=0

the folder is now hidden, but it contained all the manuals for the OEM products made by phonic

the XLS5000 was among them

Hello Massisoda.

They are similar mate but yours have different name. The Ca series became the top sellers.
This type of amplifier is very common on our place, some of the distributors here rebadge these amps.
To name a few....

Soundstandard CA20
Crell CA20
Precision Audio CA20
Lexus
Music Focus
