“The subwoofer doesn’t start in auto-standby
mode – or goes into standby too quickly”
Please check whether the level set in the
speaker/bass management for the feed device
(DVD player, sound card, receiver) is at a high
value of 4 dB to maximum. The higher
this value, the earlier the subwoofer will start. Is
the switch on the back of the subwoofer in the
middle setting “auto”?
During receiver operation: Is the subwoofer out-
cinch cable from the receiver connected to the
front in R on the subwoofer?
“There is no sound or distorted sound from one
of the satellites – all of the other satellites are
working”.
In order to pinpoint the defect more specifically,
please swap the non-functioning satellite for
a functioning satellite in order to determine
whether the defect is in the satellite or the sub-
woofer. If the previously non-functioning satellite
plays on a different channel of the subwoofer, the
defect is probably in the subwoofer electronics.
If the satellite does not play on a different chan-
nel, the satellite is defective.
“There is no sound from the subwoofer – all of
the other satellites are working”.
You can check the function of the subwoofer by
connecting the subwoofer cinch input on the
subwoofer only to the output from one of the
front channels L/R front on the sound card or a
device such as a portable CD player. If the sub-
woofer now plays, it could not have been getting
the correct signal before. Either the cinch cable
is defective or the subwoofer output of your
source appliance is not generating a signal.
Alternatively, turn the subwoofer level to “mini-
mum”, remove the subwoofer cinch cable from
the PC/DVD player/AV receiver, turn the level up
carefully and touch the inner cinch thermis-
tor with your finger. If you can hear buzzing or
crackling, there is an error in the PC/DVD player/
AV receiver or its settings. If the subwoofer stays
silent, please read the following frequently asked
questions carefully.
“The subwoofer switches itself off after a long
period at high volume (the satellites keep play-
ing)”.
It is possible that you have operated the Concept
E Magnum outside of its performance bounda-
ries.
The Concept E Magnum is an extremely good-
value, fully active system that performs very
well for its class. It has been designed for home
cinema use in smaller rooms and for PC use. It
should be taken into consideration, especially in
fully active operation with sound cards and DVD
players, that a PC speaker system cannot fill an
entire room with sound, but only where the user
is sitting. The system has not been designed for
and is not suitable for long-term use at very
high volumes.
If the system is operated when the volume is too
high, the safety cut-off in the power pack may
activate. This safety cut-off switch is prescribed
for safety reasons and prevents the power pack,
the power amplifiers and the speakers from
sustaining damage. When this cut-off switch is
activated, it means that the system has reached
its performance boundaries.
Our problem-solving tips:
Ě
Position the boxes of the Concept E Magnum
nearer to where you are sitting. Then much less
power will be needed for loud sound reproduc-
tion.
Ě
Use an AV receiver that will supply the satel-
lites with power. This takes the pressure off
the power pack and the power amplifiers of the
Concept E Magnum.
However, a fault cannot be ruled out if the Con-
cept E Magnum switches off at lower volumes in
small rooms of 20m
2
or smaller.
We are unable to authorize additional active
cooling of the power amplifier. It no longer cor-
responds to the specifications for the operation
of our products. Failures caused in this way can
clearly be attributed to negligent action by
the user. As operation with active cooling has a
direct effect on the function of the product, it
voids all guarantee claims.
Frequently asked questions
To make sure that the Concept
E Magnum is fully functional,
please carry out a “basic func-
tion test”, as described at the
end of the “Frequently Asked
Questions” chapter.
