GTC
Manual
/ english
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:
9.1
Problem
: You hear
only a distorted
or
no audio signal at all
.
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 prob-
lem change with one of the cables?
If the answer to these questions is ‘no’, the problem is being caused by the loud-
speaker with the utmost probability.
If the answer to at least one of these questions is ‘yes’, there will probably be an-
other defective device within the signal path.
9.2
GTC Sub Problem
: There is either
no or only a distorted audio signal
.
a)
Check the volumes of both the subwoofer and your signal source.
b)
Check the wiring. Is the cable defective? Are all cables connected correctly? If pos-
sible, check with new cables.
c)
Connect the subwoofer as directly to the signal source as possible (please mind the
volume!). Is another part of the signal path (e.g. mixer, audio source) defective?
9.3
GTC Sub Problem
: You hear
parasitic noises
(like humming, buzzing, soughing,
cracking).
a)
Please disconnect the signal cables. If the noises disappear, check the signal path.
b)
Make sure that all cables are properly connected, especially the signal cable between
the preamp/mixing console/etc. and the sub.
c)
If the noises can still be heard, check for other electrical devices close to the speak-
ers (mobile phones, switching power supplies, etc.). If there is no interfering device
the subwoofer will probably cause the problem.
