DAB (Digital Audio Broadcasting) is a new

multimedia broadcasting system that transmits

audio programmes with a quality comparable to

that of CDs. This is made possible by the use of a

microcomputer in the DAB tuner which uses the

radio signals sent from multiple aerials and

multi-path signals (reflected radio waves) to

boost the strength of the main signal. This makes

• The DAB system is still in a testing phase. Some

services have not been sufficiently defined or are

presently being tested. At present, such services are

not supported by the optional DAB tuner unit XT-

100DAB.

• DAB programmes are broadcast in Band-III (174 to

240 MHz) and L-Band (1,452 to 1,492 MHz), with

each band divided into channels (41 in Band-III and

23 in L-Band). One ensemble is broadcast per

channel by each DAB station.
