Before Using This Product

What is DAB?

DAB stands for Digital Audio Broadcasting. The benefits of DAB are as follows:
• High sound quality (near CD quality is normal, although this may be reduced on some
services, in order to allow more services to be broadcast).
• Interference free reception.
Note:
• Test broadcasts may be performed by some broadcast stations.
Outline
The way services are transmitted with DAB is very different to that used on MW/LW or
FM. With DAB, services are bundled into groups, normally called Ensembles or
Multiplexes. An ensemble would typically contain about 6 services, though this may vary
from 1 up to 10 or more services at any one time. Several different ensembles may be
available in any area.
Some Individual services on an ensemble may be further subdivided into service compo-
nents. The main service is called the primary service component, and the subsidiary ser-
vices are called secondary service components. This unique feature of DAB has many pos-
sible applications. A typical one would be for a sports service called SPORT RADIO for
example, to add several secondary service components for Saturday afternoon, with each
service component offering coverage of a different football match or sports event. In this
way SPORT RADIO could offer the listener the choice of several events simultaneously
rather than being forced to select one event only.
