Why is the protection LED on my Sound Magus ET150.4?
The protection LED might be on due to short circuits on the speaker leads, so check for any shorts. Also, ensure the speaker load isn't beyond the minimum. Try removing the speaker lead and resetting the amplifier. If the LED remains on, the amplifier may be faulty and require servicing.
