Troubleshooting

The following advice should help you to solve problems . If this doesn't work, please contact our hotline (see page 3) .
Take note of the warranty instructions .
Problem
The DecoderStation 7 is not
working, the display panel
2 is not illuminated .
The device is not working,
but the display panel is
illuminated .
Playback is noisy .
With stereo sources, for ex-
ample with radio playback
or a MP3 player, the rear
satellites and/or center are
inactive .
You are unable to switch
the surround configuration .
No Dolby-/DTS multi-chan-
nel sound is issued via the
connected digital source .
The digitally connected
sound card is not transmit-
ting any multi-channel
sound when playing com-
puter games .
Possible cause
The device has no power .
The volume has been set too low .
Generally speaking, this is a very low-noise
system . The system with exceptional resolution
in the high-range area can expose the poor
quality of a signal source (e .g . from MP3 files)
mostly .
MP3s, radio and many television programmes
only have stereo sound .
You are probably using a digital input . If a
Dolby or DTS signal is received on this input,
the DecoderStation 7 will automatically switch
to the correct surround configuration .
If digital sources are being played, the Decod-
erStation 7 automatically recognises the format
of the signal source . If the decoder fails to play
multi-channel sound, there is presumably no
multi-channel signal . Digital signal sources do
not always transmit multi-channel sound, but
may also emit regular stereo sound (2 .0) .
This is often the case, for example, when receiv-
ing a television signal with digital receivers .
Many soundchips are capable of producing
surround sound in real-time and issuing it via
the sound card's analogue outputs . However,
digital encoding of the calculated multi-channel
sound is also necessary in a Dolby-AC3 stream
for transmission via a digital connection . Only
if the sound card is capable of real-time encod-
ing and transmission to the decoder, can direct
decoding (that is, splitting of the signal into its
analogue components) occur .
Presently, only very few game consoles such as
the Microsoft Xbox 360 or the Sony Playstation
3 and a limited number of sound cards with
Dolby® Digital Live support are capable of
performing real-time encoding .
Solution
Check if the mains adapter plug is con-
nected to the jack 19 "12V" and to the
socket .
Increase the volume with the control dial
or "VOL +" button 25 .
Ensure that the source is sending a clear
signal .
Use the remote control to switch the
decoder to Pro-Logic mode or to one of
the DSP modes (5 . 1 stereo) .
Use the remote control to switch the
decoder to a Pro-Logic mode or to one of
the DSP modes (5 . 1 stereo) .
Connect your 5 . 1 sound card to an ana-
logue jack of the DecoderStation 7 .
