my Sony 9.2 str-za5000es receiver shuts down when I turn volume up, I've got 7 paradigm studio series speakers. I am also running a powered sub. System sounds great, nice and clear but when I crank volume receiver shuts down. Should I be looking for new receiver or add a amp or something to my system?/ I've got my crossovers all set up properly I believe. I've played with all settings on receiver and no matter what I do it always shuts down on high volume, any suggestions?
The first thing to do is make sure you have no fault in the speaker wiring. I would redo them all and make sure that there is not the slightest whisker of a +ve touching a -ve. One strand is all it takes.
From the spec I see it only has sub preout so you can not use external amplification. In the spec Sony does not say what the minimum impedance load is.
If after a careful wiring check you still have the problem, and the unit is well ventilated, I would say the unit is most likely faulty and needs return. It could be however that your receiver does not like your speakers.
If you have to return the receiver, if possible I would get a receiver with pre outs so you can use an external amp if you want.
I have to say the specs on the Sony site are very sketchy to say the least.
