Troubleshooting; No Or Distorted Signal; Parasitic Noises - Adam A3X Operation Manual

6. Troubleshooting

All ADAM products are designed and manufactured to the highest quality standards.
However, if any problems with your speaker occur, we recommend to proceed as fol-
lows:
Problem: The LED shows normal operation (green) but there is either no or only
6.1
a distorted audio signal.
If both (all) speakers are affected, the reason can probably be found within the
signal path. If only one speaker is affected, the problem will probably be within
this speaker.
a)
Check the wiring.
Is the cable defective? Are all cables connected correctly?
b) Check the signal path.
Interchange the cables of both loudspeakers. Does the problem change with one
of the cables?
Connect the monitor as directly to the signal source as possible (please mind the
volume!). Is another part of the signal path (e.g. mixer, subwoofer) defective?
If the answer to all these questions is 'no', the problem is being caused by the
loudspeaker with the utmost probability.
If the answer to at least one of these questions is 'yes', there will probably be
another defective device within the signal path.
6.2 Problem: You hear parasitic noises (like humming, buzzing, soughing,
cracking).
Please disconnect the signal cables.
If the noises disappear, check the signal path.
If the noises can still be heard, check for other electrical devices close to the
speakers (mobile phones, switching power supplies, etc.). If there is no interfer-
ing device the speaker will probably cause the problem.
