SOURCE: onkyo ts595 goes into protect mode with volume increase

HI check your speaker cables are not touching, also make sure "b" speakers are not on and that all your speakers are 4ohm or higher as this will cause the amp to shut down if they are to low an impedeance,The amp is protecting itself when it shuts down.

hope this helps.

i believe protect mode is because you have the wrong impedence speakers, they are too low (4 ohm? 6 ohm?) it chols work with 8 ohm speakers

SOURCE: my onkyo receiver (tx8511) keeps going to protect

Hi there
To answer your question;
Your amplifier goes into protect mode when it detects a fault or condition that could damage the speakers and/or the output stage.
Often caused by shorted outputs.
Although this does`nt tell you much on how to fix this problem, the best help i can give you at this point is to tell you to have it looked at by a repair shop.
Hope this help good luck
