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.
