What could cause the protection indicator to light up on the T AMP S100MK2 amplifier and indicate protection mode?
The PRO (protection) indicator lights up when one of the following situations occurs for either channel:
* 3 to 5 seconds after switching on, as the speakers are still electrically isolated from the amplifier.
* The temperature of the amplifier transistors exceeds 85 °C.
* Device malfunction.
If the device is in protection mode, please check these points. If the problem persists, it may be a malfunction of the device.
