ADAM Audio EA-SX - Handbuch (Seite 10)

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 follows:
5.1 Problem: The LED shows normal operation (green) but there is either no
or only a distorted audio signal.
If both (all) speaker channels 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 or the external amp unit.
a) Check the wiring.
Is the cable defective? Are all cables connected correctly?
b) Check the signal path.
Interchange the cables of both external amp units. Does the problem
change with one of the cables?
Connect the external amp units as directly to the signal source as pos-
sible. 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 or the external amp unit with the utmost probability.
If the answer to at least one of these questions is ‘yes’, there will prob-
ably be another defective device within the signal path.
5.2 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 interfering device the speaker will probably cause the problem.
