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 di
ff erent 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 di
ff erence between the loudest and quietest
sounds) of the reproduced audio signal. Changing the dynamic
range can a
ff ect 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 O
ff : no compression. This is the default setting.
DRC Low: medium compression.
DRC High: maximum compression.
