TROUBLESHOOTING

The speaker does not turn on

The speaker does not turn on Check for the correct power supply upstream of the system. Check that the power cable with VDE connector is correctly inserted.

The speaker turns on but makes no sound

Check audio channels (CH1, CH2 and/or CH3) proper input connections. Check that the cables used are properly working. Use only good quality cables in good condition. Check that audio sources are turned on and indicate the output signal. Check CH1 input proper sensitivity. Check CH1 proper synchronization of the Bluetooth® signal. Check MAIN output level.

The speaker outputs poor or distorted sound:

Adjust the source volume appropriate of mixer section inputs. Check that the cables used are not damaged. Use only good quality cables in good condition. Check inputs and MAIN volume levels. Check the associated Bluetooth® device output signal. Cut the level of the MIC, LINE and/or MAIN inputs. Make sure you have not connected a line signal to channel 1 with MIC sensitivity.
