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 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 radio 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.
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 off: No compression. This is the default setting.
• DRC low: Medium compression.
• DRC high: Maximum compression.
