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.
