DRC
DRC stands for Dynamic Range Control. The dynamic range for each radio program is set by the
broadcaster for each radio station and may be different for the types of program 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 program, 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 program 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 high - maximum compression.
DRC low - medium compression.
1. To adjust DRC, in DAB mode, press and hold the INFO/MENU button to enter into the Menu,
repeatedly press the ◄ or ► button followed by pressing the SELECT button to select “DRC”.
2. Press the ◄ or ► button followed by pressing the SELECT button to select and confirm the DRC
level - DRC high/low/off.
Note: An “*” will be displayed to indicate the current setting.
