What to do if [PROTECT] indicator lights and an “OUTPUT CURRENT OVER” message appears on Yamaha Amplifier display?

If the [PROTECT] indicator lights up and an “OUTPUT CURRENT OVER” message appears, it indicates that circuit protection has been engaged. This may be due to a short at the speaker terminal, amplifier terminal, or wire, or because the impedance of the connected speaker is excessively low, overloading the amplifier. To resolve this, turn the power off and check for any shorts in the speaker terminal, amplifier, or wiring. Also, verify that the speaker is not damaged and that the total impedance is not excessively low. Then, review the speaker connection and turn the power back on.
