About DAB

DAB (Digital Audio Broadcasting), also known as digital radio, is a new way of radio broadcasting. DAB is broadcast using digital signals instead of analog signals, resulting in near CD-quality sound. Analog signals (i.e. AM/FM) are susceptible to interference (i.e. distortion and noise) caused by electrical equipment, weather conditions, tall buildings, mountains, etc.; digital signals are not. Thus, with DAB, there is virtually interference-free reception and no hiss or crackle.

Another advantage of DAB is that a large amount of information can be carried within the digital signal. DAB is broadcast in blocks of data called ensembles (also known as multiplexes). Several radio programs (called primary services) can be broadcasted simultaneously in each ensemble. This means that you can choose between several radio programs within one frequency.

In addition to the audio signal, secondary services are also broadcasted and displayed on this unit’s front panel display. Part of the secondary services are text data information called DLS (Dynamic Label Segment). For more information, see page 31.

Setting up your DAB tuner

An initial scan for DAB services will need to be performed before the unit can tune into DAB broadcasts. A channel list is created during the initial scan.

Press BAND to select DAB.

The following screen appears for 2 seconds.

The unit starts to scan for DAB services in the area and add them to the channel list as they are found. The scan takes about 10 seconds.

With DAB, there is no need to remember channel frequencies, either. All broadcasts are selected by simply selecting the service name.

Notes

•You can tune the range of channels are 10A to 12D in UK.

•The sound quality and PAD/SI information are controlled by the DAB broadcaster, not this unit. Not all DAB broadcasters transmit PAD/SI information.

•DAB signals are broadcast in Band-III (174 – 240 MHz).

The number of channels found is displayed. The number is updated when new channels are found.

Once the initial scan is complete and DAB channel list created, the channels are listed in alphanumeric order.

•If no broadcast services are found, check that the antenna is correctly connected to the unit.
