Troubleshooting
1. Mixer and Amplifier Will Not Turn On.
Is the included power cord correctly connected to a power outlet?
2. Amplifier Turns Off Suddenly.
Is the vent on the top panel of the mixer blocked? Since inadequate venting will
cause the mixer to overheat, turn off the mixer and uncover the vents to allow the
mixer & amplifier to cool. After a few minutes, the mixer should reset itself and can
return to normal playback.
3. No Sound From the Speaker(s).
Are external instruments or speakers correctly connected to the mixer?
Are the LEVEL controls of all relevant channels set to appropriate levels?
4. Distortion or Noise in the Audio Signal.
Are the LEVEL controls of all relevant channels set to appropriate levels?
5. Output Level is Low.
Are the LEVEL controls of all relevant channels set to appropriate levels?
Is the input signal from the connected device set to an appropriate level?
6. Bluetooth not working.
Be sure your device is paired. See page 10.
