Why does my DAB radio’s signal lag behind my FM radio’s signal?
No need to adjust your radio, it's just the way these devices convert signals that slows them down.

In DAB, the transmission equipment samples the signal in chunks, so it takes a few fractions of a second to convert it into binary. When the signal arrives at your DAB receiver, it streams the data into a buffer, which then passes it to the digital-analogue converter. The lag is the result of these combined sampling delays.
