      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.

      If your Qtx Speakers have power LED lit, but you're not getting any sound from external inputs, first, check that the leads are OK and properly connected. Next, check the volume and on/off switch on the external mic or line source. Make sure the VOLUME or MIC VOLUME control is not fully down. Finally, check if "LINE IN" is displayed on the LCD for AUX input by pressing MP3/LINE.

      If the power LED is lit on your Qtx Speakers, but there is no VHF output, you should check the 9V batteries in the wireless transmitters and ensure that the wireless transmitters are switched on. Also, verify that the VHF POWER is switched on and the MIC VOLUME is not turned down. Finally, check the RF A and RF B LEDs for a radio signal.
