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.
