Manual Tune

The ‘Manual tune’ function is used as a reference to see if stations are being broadcast

over set frequencies. It is not possible to store a station from here, although the

signal strength will be displayed.

Using the manual tune feature, select a speciﬁc digital radio channel frequency and

then manually adjust the aerial, or the location of the AirStream 10, to obtain the

strongest possible signal for that channel.

When in DAB mode, press the ‘Menu’ button.1.

Use the ‘Tune/Select Dial’ to scroll to and select ‘Manual tune’.2.

Use the ‘Tune/Select Dial’ to scroll through the digital radio frequencies and 3.

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 bars. The row of bars indicate the actual signal strength that you

are receiving. The stronger the signal, the larger the number of signal bars that

will be displayed.

If a signal is detected, the frequency will scroll along the display showing the

station name. Example:

Note:

If the signal strength box is empty, this indicates no signal reception 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 certain types of programme broadcast. For

example, pop, classical music or a chat show. The Dynamic Range Control signal is

transmitted in parallel with the audio signal for each programme. With the AirStream

10, it is possible to 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 so that it will be more suited to your listening conditions and your

own personal listening requirements. For example, if within a noisy environment,

where quiet sounds can 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:

In DAB mode, press the ‘Menu’ button.1.

Use the ‘Tune/Select Dial’ to scroll to and select ‘DRC’. The current DRC setting 2.

will have an asterisk ( ) next to it.

Use the ‘Tune/Select Dial’ to scroll through the 3 levels of compression and 3.

press to select the preferred choice. We would suggest trying different levels of

compression to see which suits you best.

Note:

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

stations and presets.
