6. TROUBLESHOOTING

The speaker does not power up:
1. Check that the system is connected to a working power supply.
2. Check that the power cable with the POWERCON® TRUE1 connector is plugged in correctly.
3. If the problem persists, contact an authorised service centre.
The monitor turns on but does not produce any sound:
1. Check that the audio signal inputs are connected correctly, preferably using cables with Neutrik®
connectors.
2. Check that the cables used are not damaged.
3. Check that the mixer or audio source is on and clearly shows an output signal.
The sound from the monitor is distorted:
1. With the system powered on, first adjust the volume of the audio source. If the source LIMITER LED is on,
the signal may already be distorted before it reaches the speaker.
2. Check that the connection cables are not damaged. If they are, replace them (a damaged cable may cause
signal loss or alteration).
3. Check the preset EQ saved on the Service/User button that alters the frequency response of the output
signal.
