“The satellites hiss”
In principle the Concept E is a very low-noise
system. In the high range area, the very high-
resolution quality speaker systems can expose
the defective quality of a signal source (e.g. from
mp3 files or analogue cassette recordings) that
can hardly be heard on less high-quality boxes.
You can check the basic noise level by connect-
ing an output signal (via a cinch cable) from an
external source that is guaranteed to be good
quality – such as a music CD on a portable CD
player – to the front L/R input on the subwoofer.
If all of the satellites are now playing noise-free,
then they were not getting the correct signal
before. Either the cinch cable is defective (try
swapping them) or the output of your source ap-
pliance is not producing a sufficient signal.
However, if you continue to hear increased
noise on this channel there is possibly a fault
in the Concept E. Please check which satellite
is affected by swapping the satellites over and
finding out whether it is the satellite or the
subwoofer electronics that are generating the
excessive noise. If the fault “moves” with the sat-
ellite, the satellite is affected. On the other hand,
if the noise remains on the same channel, the
subwoofer amplifier electronics are responsible.
“The set loses its settings when I switch it off
completely”
This is normal. The mains switch and the mains
plug disconnect the subwoofer from the elec-
tricity supply and mean that the settings are
lost. We therefore recommend using standby
mode on a separate supply – this will ensure all
of your settings are kept.
We also think that it’s a good idea to make all
of the interrelated settings of the individual
channels (= all except master volume and, if
necessary, subwoofers) on the AV receiver, DVD
player or PC sound card driver software, not on
the Concept E.
“When I switch the PC on or off I can hear a
loud snapping or crackling.”
The speaker system reproduces any kind of
acoustic signal that it receives from the signal
source. It cannot differentiate between useful
and disruptive signals. When the PC’s sound card
transfers the on/off impulses to the box set, the
speakers will reproduce it. These will not usually
damage your speakers. Nevertheless, we recom-
mend minimising the volume using the PC’s
software before switching off, in order to limit
these strong impulses.
Basic function test:
You can check the function of the subwoofer and
the satellites by only connecting the (stereo) sig-
nal from an external source that is guaranteed
to be good quality – such as a music CD played
on a (portable) CD player – via a cinch cable
(and possibly a Y adaptor) with the front input
L/R on the subwoofer. The other four inputs on
the subwoofer do not need to be occupied (=
cinch cable disconnected). With this connection
plug arrangement of front in L/R, the Concept
E Magnum amplifier activates all satellites and
the subwoofer through internal distribution.
If the subwoofer and all five satellites now play
correctly via a directly connected CD player, the
Concept E Magnum was not receiving the correct
signal before. Either the cinch cable is defective
(try exchanging it) or the output of your source
appliance is not producing the correct signal.
If you continue to experience unwanted noise/
individual malfunctions, there is possibly a de-
fect in the Teufel system.
