Troubleshooting TROUBLESHOOTING 1. NO SOUND: Power indicator is Off. 5. BAD AUDIO OR MICROPHONE SOUNDS REMEDY: REMEDY: • Check the AC Plug. Check the source of audio (CD, DVD) to see if it’s scratched. • Ensure that the AC outlet works by testing other devices. If too many amplifiers are used on one outlet, the building's circuit breaker may trip and shut off power. Check audio cables or microphone cables. Use a better audio cable or 3pin XLR microphone cable.
