Overview of DAB

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
DAB almost immune to radio interference even
in a moving object such as a car.
Each DAB station bundles radio programmes
(services) into an ensemble which it then
broadcasts. Each service contains one or more
components. All ensembles, services, and
components are identified by name, so you can
access any of them without having to know their
frequencies.

Notes
• 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.
