Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Protect mode


Check to make sure that NONE of your speaker wires on the outputs are touching each other or that there is anything obstructing any the output terminals. Also since this a 5.3 model check all the SUB outputs for the same condition (although probably not as much an issue since they are line level outputs) as well as the condition of all interconnects and speaker cables. After that check all the physical connections at every speaker to make sure you haven't shorted out an output at that location.

Protect message


Protect means that a fault was detected, disconnect all the speakers

and connect one at a time to find the cause.

If symptoms persist , it needs repair, output stage or power supply

circuits should be the preliminary things to check.

Integra DTM 3.5 AV receiver. The unit goes into protect mode when I try to turn it on and then shuts itself off. How do I fix it?


Do more triage first.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

Display shows "protect" and shuts down


There is a short on one of the speakers cables or the speakers themselves. Test all of them with an ohmmeter.
