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.
