FM Tuner About DAB
Tuning range ..........................87.50 - 108.00 MHz (50 kHz steps) With this unit you can receive and listen to Digital Audio
Signal-to-Noise ratio ......................65 dB (Mono), 60 dB (Stereo) Broadcast (DAB) programmes. DAB uses digital, not analogue
signals, resulting in near CD-quality audio with virtually
interference-free reception. Along with superior quality audio,
DAB Tuner DAB can also deliver additional audio channels and text. In the
Tunig range ......................................Band 3, 174 MHz - 240 MHz future, computer data and images are also possible.
Input ................................................................Telescopic antenna
Max signal .................................................................. 3 dBm typ Digital radio is broadcast as groups of data called ensembles or
Sensitivity .................................................................. 96 dBm typ multiplexes. Each multiplex can contain a number of stations
Adjacent channel rejection ..............................................35 dB typ (services) and each station contains a primary service and can
Digital output ............................................24 bit/48 kHz resolution contain secondary services as illustrated in the following diagram.

Weight ..................................................................................2.0 kg Each multiplex is transmitted in a set frequency range and
Operating temperature ................................................0 °C - 50 °C received by this unit for decoding. You can receive multiplexes
broadcast in the 174240 MHz frequency band and store the
services in each multiplex for you to access. The number of
Accessories multiplexes you receive depend on your location. Channels used
AC adaptor x 1 in the UK are in the range 10A to 12D.
· Design and specifications are subject to change without notice. Multiplexes and stations have labels (names) that are used to
identify them. Instead of needing to know the particular frequency
of your favourite broadcast, you can simply select the station
name. Secondary services and additional data such as text or
multiplex info are also available.
