Take note of the warranty instructions.
Problem Possible cause Solution
The DecoderStation 7 is not
working, the display panel
2 is not illuminated.
The device has no power. Check if the mains adapter plug is con-
nected to the jack 19 “12V” and to the
socket.
The device is not working,
but the display panel is
illuminated.
The volume has been set too low. Increase the volume with the control dial
or “VOL +” button 25.
Playback is noisy. 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.
Ensure that the source is sending a clear
signal.
With stereo sources, for ex-
ample with radio playback
or a MP3 player, the rear
satellites and/or center are
inactive.
MP3s, radio and many television programmes
only have stereo sound.
Use the remote control to switch the
decoder to Pro-Logic mode or to one of
the DSP modes (5.1 stereo).
You are unable to switch
the surround configuration.
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.
No Dolby-/DTS multi-chan-
nel sound is issued via the
connected digital source.
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.
Use the remote control to switch the
decoder to a Pro-Logic mode or to one of
the DSP modes (5.1 stereo).
The digitally connected
sound card is not transmit-
ting any multi-channel
sound when playing com-
puter games.
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.
Connect your 5.1 sound card to an ana-
logue jack of the DecoderStation 7.
