Question about Onkyo TX-LR552 6.1 Channels Receiver
AMPLIFIER SHUTS IT SELF OFF IF VOLUME GOES OVER 50.
You may be using 4 ohm speakers on an 8 ohms rated amplifier, or you are trying to play the amp excessivly loud for its design apability, or the amp is not strong enough for the speakers, or there is a fault condition where the output stage is pulling too much power, and the protection circuit is kicking in, because of one of these faults. It is also possible that the protection circuit has a fault condition. A quick test,though. Disconnect ALL speaker wires from the receiver. Turn on the receiver - if the volume increase makes it cut off, the problem is definitely in the receiver. If so: You should give the amp to a qualified shop that has the proper test equipment to properly diagnose the amp for its power rating over the complete designed response, and do an evalution of its dynamic head room and dynamic range, to see if it meets specs. If something is out of specs, then it can be serviced.
