6. TROUBLESHOOTING

The speaker will not turn on:
1. Check that power supply is present upstream of the installation.
2. Ensure that the power supply cable with POWERCON connector is properly plugged in.
The speaker turns on but produces no sound:
1. Ensure that audio signal input connections have been performed properly, preferably using cables with
Neutrik® connectors.
2. Check the cables for damage.
3. Ensure that the mixer or audio source is on and an output signal is present.
4. Check for the proper Audio Input Sensitivity level (3) at the amplifier control panel.
Speaker sound is distorted:
1. With the system on, first adjust source volume, and then set the Audio Input Sensitivity rotary switch
to the appropriate value. Look at the LIMITER LED; if on, it means that the speaker is operating under
distortion conditions.
2. Check the cables for damage and replace them as required (a damaged cable may lead to signal loss or
alteration).
3. Ensure that the LINE-MIC switch is set to match actual input connection.
4. Check the settings of the DSP preset rotary switch that affect output frequency response. To this end,
please read section FIRST POWER-UP.
Stage monitoring is insufficient
1. Ensure that the speaker is properly positioned on the stage according to the indicated sound dispersion
pattern and the positions shown in section INSTALLATION EXAMPLES.
2. Check for any obstacles directly between performer and monitor.
3. Consider adding more LVX XM12 modules.
