Make sure you have a good ground connection. The ground wire should be solidly connected to the vehicle chassis in a paint-free location. If the ground is connected badly, the protect light will come on.

The "PROTECT" light indicator came on and now the


The protect light generally comes on when the is a short in the speaker cabling. as a test, turn on the mixer without any speakers hooked up. If it still goes into protect mode the problem is in the mixer. Take it to your local music store and have their tech look at it. if it doesn't go into protect, check the speaker cables by plugging them in one at a time. The bad one will send it into protect.

good luck

The protect light is the only light that comes on


Either one of the amps or the power supply has blown. The protect light means the power supply has been shut down due to overcurrent. Take unit in for repair. These are hard to work on due to packaging.

Power light turns from green to red protect mode and then there is no sound coming from my speakers


there are 2 reasons for it to be going into protect mode 1 is heat 2 is the load on it. if it is going into protect mode soon after it starts there is a problem with the speaker. if it is after it has been on for a while it is that the amp itself is overheating. hope this answers your question

Protect light


check speaker wire is not grounded and/or the proper impedence is followed. Those amplifiers are 2 ohm stereo stable. Know the difference.

Remove speaker wires and try amplifier.
Add 1 speaker at a time until the problem recreates itself, or test them with an ohm meter.

The most likely reason for it to go into protect is shorted output transistors.

Disconnect all speaker wires and signal cables from the amp. If it powers up (no protect light), the wiring needs to be checked. If it still shuts down (goes into protect), the amp likely has blown output transistors.
