====Bit rates====
An ensemble has a maximum [[bit rate]] that can be carried, but this depends on which error protection level is used. However, all DAB multiplexes can carry a total of 864 "capacity units". The number of capacity units, or CU, that a certain bit-rate level requires depends on the amount of [[error correction]] added to the transmission, as described above. In the UK, most services transmit using 'protection level three', which provides an average [[ECC code rate]] of approximately {{sfrac|1|2}}, equating to a maximum bit rate per multiplex of 1,184&nbsp;kbit/s.
