9 TROUBLESHOOTING
9.1 System not powering up
•
Check the Overvoltage Protection leds
- No LED lit: Check if voltage is arriving to the PowerCon socket, and if mains
cable is in good condition. If yes, the overvoltage circuit may be damaged.
Contact support.
- Red (>250V). Voltage arriving to the PowerCon socket is above 250VAC.
Check the mains voltage is in the rated limits (/-10%). If mains
voltage is OK, the overvoltage circuit may be damaged. Contact support.
- Blue (Power On): Overvoltage circuit is functioning properly. If none of the
Status LEDs or the touchscreen are being lit, the fuse in the power module may
be blown. The replacement of this fuse must be carried out by specialized
personnel as it is an internal component of the amplifier module.
9.2 No output sound
•
Check with the indicators (Signal Present LED & Touchscreen) that the signal is
being received by the system.
•
Check that the signal cables are in good condition and connected at both ends
•
The mixer output level must not be at minimum.
•
Check that the mixer channel is not muted.
•
Check that the system is not in MUTE or STANDBY (MUTE LED or STANDBY LED)
not lit. If yes, go inside the menu using the touchscreen and deactivate them:
- To disable the Standby go to SETUP and select STANDBY OFF.
- To disable the MUTE go to AUDIO, GAIN and push the icon with a loudspeaker.
•
Check that the system GAIN is not set to the minimum. To do that, go to the AUDIO
setting using the touchscreen, select GAIN and move the slider to the 0dB position.
9.3 Distorted output signal
•
The system is being saturated with a very high input signal, frequently caused by
the same mixer. Check the output level or mixer gain channels.
9.4 Poor bass levels
•
Check the polarity on the signal connections between the mixer and cabinets. If any
of the Pins (1, 2 or 3) have been inverted at the cable ends, this will cause significant
performance and sound quality loss.
9.5 Noise and Hum
•
Check that all the connections to the active units are in good condition.
•
Avoid intertwining between mains supply cables or proximity to transformers or
Electromagnetic (EMI) emitting devices.
•
Check there is no light intensity regulator in the same AC circuit as the unit. ALWAYS
connect the sound and light circuits in different phases.
•
Check that there is a proper connection to EARTH in the electrical installation.
