Sub7
Manual
/ English
All ADAM products are designed and manufactured to the highest quality standards.
However, if any problems with your subwoofer occur, we recommend to proceed as
follows:
6.1
Problem
: The LED shows normal operation (green) but there is either
no or only
a distorted audio signal
.
Check the volumes of both the subwoofer and your signal source.
Check the wiring. Is the cable defective? Are all cables connected correctly? If pos-
sible, check with new cables.
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?
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.
Make sure that all cables are properly connected, especially the signal cable be-
tween the preamp/mixing console/etc. and the sub.
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 subwoofer will probably cause the problem.
