Data compression
DAB makes use of effects of human hearing for data compression.
The human ear does not perceive sounds below a minimum volume. Data below this silence thresh-
old can therefore be filtered out.
This is possible because every digital data flow saves the associated relative volume in comparison
to other units for every information unit as well. In a sound signal, the louder shares also overlay the
softer shares at a certain threshold. All sound information in a piece of music that falls below the
listening threshold can be filtered out of the signal to be transmitted.
This reduces the data flow to be transmitted without any perceptible sound difference for the
listener.
Audio Stream
Audio streams are continuous data streams at DAB that contain MPEG 1 audio layer 2 frames and
thus represent acoustic information. Common radio programmes can be transmitted this way and
listened to by the receiver.
DAB not only provides radio at excellent sound quality, but also additional information. This may refer
to the current programme (DLS e.g. title, interpreter) or be independent of this (e.g. news, weather,
traffic, advice).
c) Operation in DAB-Mode
The device will automatically start station scanning when it is switched off for the first time. If no
station is received, "Not available" is displayed. This means that either no reception is possible, or
reception is very weak. In this case, you need to change location.
Search
• The automatic "Full scan" scans all DAB channels and thus will find all stations that are broadcast
in the reception area.
• Push the MENU (5) button and select "Full scan" with the TUNING (12) buttons.
• Push the button ENTER (11) to confirm.
• The scan starts and the display (13) shows a progress bar.
• After completion of the station scan, the first station in alphanumeric order is played back.
If no station is found, check the alignment of the telescopic aerial (18) and if required,
change the site of setup of your device.
Check if DAB stations are broadcast in your area.
