I recently purchaced a JVC A/V Receiver model rx-6040. Every thing works great on it and i love all the features. The only problem is every since i bought it the receiver is shutting down and flashing OVERLOAD but only when i turn the volume past 30( It gos all the way up to 50). I then turn it off then on and it works fine until i turn it up again. Every time is different. Once it happened at 26 and another at 38( the highest i ever got it). It all depends on what song is playing. If its a metal song with loud guitar it will shut down at like 32. Some songs lower and some higher. What i think might be causing the problem is my rear speakers. I havent saved up enough money to buy good speakers so I bought a cheap set of suround sound and center speakers.The fronts are reated at 250 watts each so i know they are fine. But the rear are only 60 watts each. If the volume gos to 50 on the receiver and it puts out 100 watts per channel, if you do the math then when the volume is at 30 it is sendong 60 watts which is the max. But would this be causing the receiver to shut down? I know technology is way more advanced in newer receivers but can they actually tell how much power your speakers can handle and shut off to protect them? This has been getting on my nervs latly i want to figure it out. When you think about it im only getting 60% of what i paid for i want the whole thing. Well any help would be greatly appricheated. Thanks P.S. I dont have anyother reear speakers to plug in to see if that is the problen. So if it is them ill have to go out and buy a new pair.
