5. TROUBLESHOOTING

The speaker doesn't turn on:
1. Check that the power supply upstream of the system is working properly
2. Check that the power cord is properly plugged
3. Check that the ON/OFF selector is turned to "I".
The speaker turns on but it doesn't output any sound:
1. Check that the input connections of the main audio signal and of the auxiliary one, if any, have been
performed properly
2. Check that the cables in use are not damaged
3. Check that the mixer or the audio source are on and that they clearly indicate the presence of an
output signal to the speaker.
4. Check that the level of the main audio volume and of the auxiliary one, if any, are set to an appropriate
value.
The speaker outputs a distorted sound:
1. Check that the Audio Input Sensitivity rotary encoder is set on the correct value (0 dB). It should be
noted that if the LIMITER LED is on, it indicates the speaker is operating under distorting conditions.
2. Check that the cables in use are not damaged; should that be the case, replace them (a damaged cable
may result in a signal loss or alteration).
3. Check that the LINE-MIC switch matches the actual input connection.
4. Check the settings of the rotary encoder DSP preset affecting the output frequency response. To this
purpose please refer to section FIRST SWITCH-ON.
