manual tune
The 'Manual tune' function is used as a reference to see if stations are being
broadcast over set frequencies. you will not be able to store a station from here, you
will just be able to see the signal strength.
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 AirStream 10, to
get the strongest possible signal for that channel in your location.
1.
When in DAB mode, press the 'Menu' button.
2.
use the 'Tune/Select Dial' to scroll to and select 'Manual tune'.
3.
use the 'Tune/Select Dial' to scroll through the digital radio frequencies and
press to select. The AirStream 10 will display the radio frequency and a strength
indicator, in the form of a rectangle with fluctuating (depending on signal
strength) solid indicator blocks. The row of solid rectangles indicate the actual
signal strength that you are receiving. The stronger the signal, the further to the
right the row of solid rectangles will be.
If a signal is found, the frequency will scroll along the display showing the station
name. example:

Note:
If the signal strength box is empty, 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 AirStream 10, to obtain the maximum signal
strength and press the [Return key] to exit back.
Dynamic range control
The dynamic range for each radio programme is set by the broadcaster for each
radio station and may be different for the types of programme broadcast, 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 programme and with your
AirStream 10, you can use this control signal to expand or 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 'quality
of sound' of the programme that you hear so that it will be more suited to your
listening conditions and your own personal listening requirements. For example, if
you are in a noisy environment, where quiet sounds might be swamped, setting the
compression to maximum (DRC High) will 'boost' the quiet sounds, whilst keeping
the loudest sounds at their original level.
There are 3 levels of compression:
DRC Off - no compression. This is the default setting.
DRC Low - medium compression.
DRC High - maximum compression.
To change the Dynamic Range Control:

The DRC Level cannot be set for each preset. The same level will be used for all
stations and presets.
