A delay-action), close the

The speakers hum.
The humming is caused by line distur-
bance.
Buy a line filter and connect the device to it.
The humming is caused by a multiple
socket.
Use another multiple socket or connect the
subwoofer directly to a wall socket. Connec-
ting the mains plug with the socket the other
way around may also help.
The playback has interfe-
rence.
The Concept D 500 THX is generally a
very low-noise system. In the high range
area, very good-quality high-resolution
speaker systems can expose the poor
quality of a signal source (e. g. from MP3
files).
Make sure that the source sends a clean
signal to the Concept D 500 THX.
