Full Scan; Manual Tune; Drc (Dynamic Range Control); Prune - Albrecht Audio DR 900 BT Mode D'emploi

6.7.1 Full Scan:

Full scan thoroughly searches all channels for stations available in your region. Doing a full scan
requires about 1-3 minutes depending on the amount of stations.

6.7.2 Manual Tune

Using the manual tune feature, you can select a specific digital radio channel frequency and then
manually adjust the aerial or the location of the radio to get the strongest possible signal for that
channel in your location.
Use the "Tune" wheel to scroll through the digital radio frequencies and preset "Select". An empty
口 will appear on the second line of the display to indicate the actual signal strength that you are
receiving. The stronger the signal, the further to the right of the row of solid rectangles it will be.
Note: If only an empty 口 is displayed, you are not receiving any signal at all for that particular digital
radio channel in your area.
Adjust the position of the aerial on the radio to obtain the maximum signal strength and press
"Select" to exit back.

6.7.3 DRC (Dynamic range control)

The dynamic range for each radio program is set by the broadcaster for each radio station and it
differs for different types of programs such as pop or classical music or a chat show. The dynamic
range control signal is transmitted in parallel with the audio signal for each program and your DAB
radio can use this control signal to compress the dynamic range (the difference between the loudest
and quietest sounds) of the reproduced audio signal. Changing the dynamic range can affect the
"Loudness" and/or the "quality of sound" of the program that you hear. It will be more suited to your
listening conditions and your own personal listening requirements e.g. in a noisy environment,
where quiet sounds might be swamped, setting the compression to maximum will "Boost" the quiet
sounds, while keeping the loudest sounds at their original level.
There are 3 levels of compression:
• DRC off: No compression, this is the default setting.
• DRC high: Maximum compression.
• DRC low: Medium compression.
But this works only with radio stations which support this feature.

6.7.4 Prune

In case the station list contains lots of outdated stations, maybe because you permanently moved to
a different region, you might want to get rid of those list entries.
By selecting the Prune function all stations which are not available at the moment are deleted from
your station list.
