Bang & Olufsen BeoSound 4 - User Guide - Manual (Page 13)

DAB AERIAL ADJUSTMENT … This menu contains
an indicator bar, which shows the strength of
DAB signal reception and the risk of signal drop-
out. Watch the indicator bar while you adjust
your aerial. When the signal is strong enough,
sound is transmitted.
– The indicator bar extends rightward if signal
strength increases, and reverses direction if it
decreases.
– The indicator bar moves through a shaded and
a white fi eld. The shaded fi eld to the left
indicates that there is a signifi cant risk of
periodic signal drop-out. The white fi eld to the
right indicates that the risk of signal drop-out is
minimal.
DAB DRC … For certain DAB stations, you can
adjust audio signal compression with the DRC
(Dynamic Range Control) function. Compression
compensates for sources of noise in your
immediate surroundings.
There are twelve possible settings, with three
values to guide you:
OFF (no compression)
NOM (recommended by the DAB provider)
MAX (maximum compression, twice that
recommended by the DAB provider).
If you have adjusted audio signal compression
and you are listening to a DAB station broadcast
with DRC, ‘DRC’ appears in the lower right
corner of the display. DAB DRC menu settings
have no effect for stations not broadcast with
DRC.
If DAB tuning results in too many stations for
the Program List …
> The available stations appear in the STORE
PROGRAM menu.
> Turn the wheel to move between stations.
> Press GO to store a station.
> If the menu is empty, or if you do not want to
store more stations, press EXIT to leave the
menu.
Radio text – text information about the current
station and broadcaster – is supported by
BeoSound 4. You can set your system to display
radio text via the DISPLAY SETUP menu. For
further information, refer to the chapter ‘Make
option settings’ on page 18.
Note that you must select a channel number with
a signal before adjusting the aerial. Check your
DAB broadcasters’ websites for channel numbers.
Digital Audio Broadcast (DAB) providers send
stations in groups called ensembles*.
A channel contains a single ensemble, and an
ensemble typically contains 5–10 services*.
When a DAB signal is found, all the stations
in the signal are registered. When tuning is
complete and more than 99 stations are
found, you go through a list of the individual
stations and select the ones you wish to store.
When new DAB stations become available,
you tune them in with the auto tuning
function. This tunes in new stations and
leaves previously stored stations unchanged.
*Some DAB providers call an ensemble a ‘multiplex’,
or call a service a ‘station’.
