Dynamic range control (DRC)
In DAB mode:
The dynamic range for each radio programme is set by the broadcaster for each radio
station and may be diferent 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 radio you can use this
control signal to expand or compress the dynamic range (the diference between the
loudest and quietest sounds) of the reproduced audio signal� Changing the dynamic
range can afect 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� e�g� in a noisy environment, where quiet sounds might be
swamped, setting the compression to maximum will ‘boost’ the quiet sounds, whilst
keeping the loudest sounds at their original level�
There are 3 levels of compression:
•
DRC Of - no compression� This is the default setting�
•
DRC Low - medium compression�
•
DRC High - maximum compression�
