It can be set independently per station. As an example, in Norway the NRK Jazz channel transmits at 64 kbit/s, while NRK Klassisk (classical music) transmits at 96 kbit/s.

96 kbit/s AAC still isn't enough IMHO. 128 kbit/s OPUS would be awesome :)

DAB mandated the use of MP2, which pre-dated MP3. DAB+ uses MP4 aacPlus(HE-AAC v2).
Unfortunately this doesn't improve sound quality because stations use the extra efficiency to switch to lower bit-rates.
Some countries have stations at 48kbps. The UK is leading the drive to lower sound quality with DAB+ stations on the SDL multiplex at 32kbps.
Note that DAB+ also hides a cost increase because stations have to pay Fraunhofer for its patents. Fun, isn't it? ;-)
