Hello. After updating the console with firmware 1.5.1, the led of MIC 1 started flashing for no reason. Flashes without any microphone connected, flashes with the microphone connected, flashes with the ON key on, with the ON key off, with or without volume, with or without any cable connected (MASTER and power supply), flashes with TALKOVER enabled and disabled . With the old firmware it never flashed. An intermittent and continuous flash. But anyway the console works, the songs are selected and started normally and if I were to connect a microphone to the MIC 1 input, despite the flashing, the same microphone works correctly. I thought and hoped that with the 1.5.2 update I would fix it, but this problem remains. And this flashing is done only by the led of MIC 1. The led of MIC 2 remains off and in any case it also works correctly. Has it happened to anyone else? Thank you and good evening.
