What to do if power LED is lit but there is no USB/SD player output on my Qtx QR12PA Speakers?
- MMrs. Julie Gutierrez DDSAug 16, 2025
If your Qtx Speakers have power LED lit, but there is no USB/SD player output, verify that the USB or SD has correct audio files and is connected properly. Try pressing the MP3/LINE button and then the >II button. Also, ensure that the VOLUME is not turned down. Press and hold the “VOL +” button. Finally, check the LCD display to see moving numbers.
