Every time i turn the volume above 46 my sony home audio center goes in protect mode


Hi
if an amplifier goes to protection mode it basically means that there is "A short on the speaker connections"..pls replace the speaker connection of the "CENTER " to make sure even a tiny cable lead not to touch the other ( + and - )...by this means pls check all the other speaker connections as well..if problem persists please let me know for further help..
Hope this helps! Take care and please Remember to rate/vote

Dear Sirs, I have a Pioneer AV Receiver model VSX-817 and is connected to Monitor Audio Speakers (Fronts: BR5, Center: BR-LCR, Rears: BR1), Sub: MS309 (Mordaunt Short). I have connected each front...


Did you remember to remove the shorting link on the MA BR5 speaker terminal ..When you biwire the speakers you should remember to loosen the speaker terminal nuts and remove the shorting link plate between the HF and the LF terminals or you will short the amplifiers two channels together through the link. And modern amplifiers will take a lot of abuse at low volumes but at high volumes the protection circuit will turn off the device.

I'd treat this symptom as "DISPLAY not lit and power indicator is flashing rapidly." under Troubleshooting on Page 60.


and I'd evaluate the speaker load you're presenting to make sure it's effectively higher than 6-0hms per speaker channel.

The protect light goes on and the unit shuts down when I increase the volume?


This sounds like a problem in at least one channel of the power amplifier. Only an experienced audio technician should attempt to repair this problem. It is not an obvious or easy fault for a novice to diagnose or repair. ie, you have a situation in which the unit seems to function at low power levels, but the problem become apparent at higher power levels.

My denon avr1200 receiver once it is turned on goes into Protection mode. How do you reset or make work?


The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

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.

Protect Mode


There are bad connections on the main board that are effected by heat. I would suspect that when the volume level is higher, the system shuts down sooner. This should be a simple repair that will not require parts. If you can solder, you should be able to repair this yourself. If not, the cost will be the local labor rate.
