DAB Display Modes
The bottom line of the display can be switched to show different items of information that may
be transmitted with a DAB station.
• Press the Info button to scroll through the display modes while listening to a DAB station.
The option are as follows:
DLS (Scrolling text)
Signal strength
Programme type
Multiplex name
Multiplex number/frequency
Signal error rate
Audio bit rate/encoding
Time
Date
DLS (Dynamic Label Segment):
This is a scrolling message giving real-time information - song titles, news headlines, etc.
SIGNAL STRENGTH:
This setting will display a signal strength bar graph. The longer the bar graph, the stronger the
signal. Setting the display to show signal strength is useful when setting up the aerial for the
strongest signal.
PROGRAMME TYPE:
This describes the style of the programme being broadcast.
MULTIPLEX NAME:
DAB Digital radio stations are broadcast in multiplexes. Each multiplex is a bundle of radio
stations transmitted in a single frequency. There are national and local multiplexes; local ones
contain stations specific to your area. This option displays the name of the multiplex name that
contains the station you are listening to.
MULTIPLEX NUMBER/FREQ:
This option will display the multiplex number and frequency that contains the station you are
listening to.
SIGNAL ERROR RATE:
This option will display the level of signal errors in the current broadcast. The lower the number,
the better the quality of the signal.
BIT RATE:
DAB allows broadcasters to vary the BIT RATE (or the amount by which an audio signal can be
compressed) depending on the type of broadcast. This enables the amount of stations on a
multiplex to be maximised. Speech and News are often broadcast at a lower Bit Rate; music
needs a higher Bit Rate for good fidelity.
TIME AND DATE:
Time and date are updated by broadcasted information.
