Troubleshooting
PROBLEM
No sound/
distorted sound
No power
Poor Mic sound
Mic feedback
Buzzing sound
1. Make sure the unit is plugged in and the power switch is in the
ON position.
2. Check that the power cable is plugged in tightly to the unit.
3. Check and replace the fuse if necessary. See the fuse
replacement diagram on page 14.
4. If people or equipment tend to step on and roll over or stretch
your power cable it can get damaged. Always try a second cable
to test for shorts in original cable. Dispose of original damaged
power cables immediately.
1. Make sure you are using the Mic In port.
2. If using wireless mics connect them to the Line input of your mixer.
Point the mics away from the speaker. Make sure the mics are
behind the speaker, not in front of it.
Make sure you are using a proper cable. For ¼˝ cables, there are
3 types: instrument, TS (unbalanced), and TRS (balanced). Check
the requirements of the connected gear and the input of the
speaker and make sure you are using the appropriate cable.
1. Check that all appropriate cables are plugged in correctly.
2. Check volume settings (Volume 1, Volume 2, and MP3 Volume).
3. Be sure Volume and Gain of appropriate channels are set
above level 0 and matched correctly.
4. Be sure your microphone is on.
5. If using a mixing console, make sure fader and balance are set
to center positions and levels are increased.
6. If volume and EQ settings are maxed out, turn one of them
down as you may be overdriving the unit.

5. Move both devices away from other Bluetooth devices, micro-
waves, wireless routers, and other electronics.
6. Make sure that the unit is not paired to a previously paired
device.
