Dynamic Range Control (Drc) - Bush 4023856 Instruction Manual

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.
1. Press and release the 'Menu' button, and use the 'Tune/Select' rotary control to
scroll to '<DRC>'.
2. Press the rotary control to 'Select'. The current DRC setting will have an '*' next to
it.
3. Use the rotary control to scroll through the options and press the rotary control to
confirm.
4. Press and release the 'Menu' button to return to the station display.
