DRC value

DRC (Dynamic Range Control) value makes the quieter sounds in a broadcast easier to hear at low volume or in a noisy environment. The DRC level of a broadcast is set by the station and sent with the signal. At the time of writing in the UK only BBC Radio 3 and 4 regularly use DRC. Check with the broadcasters to find out if they use DRC on their stations.

The DRC value setting is only available if VET is set Off see the following section for details. Turn the Tune knob to scroll through the following options and push to select one:

DRC 0 DRC is switched off. Any DRC level broadcast will be ignored. DRC ½ DRC level is set to ½ that sent with the broadcast.

DRC 1 Applies the DRC level as sent with the broadcast.

VET levelling

VET (Volume Equalisation Technology) helps level volume levels across

different stations making each sound as if it is at the same volume. It does this by constantly monitoring the stations on your station list and lowering or raising their volume to meet an optimum level.

Note When VET is On use of DRC would distort the levelling effect so DRC is disabled when VET is On.

Turn the Tune knob and push to set VET On or Off.
