The fully software-upgradable Digital Radio Module is based on
the latest technology. It is capable of receiving Digital Radio
transmissions on both band III (174 MHz - 240 MHz) and L-band
(1452 MHz - 1492 MHz) using a 50
Ω
antenna. It supports all
existing DAB modes (I, II, III and IV), features high selectivity
through the use of a high-order recursive digital filter and
supports the sampling rates of 24kHz and 48kHz.
The timing of digital data decoded from the Digital Radio signal
is as important as the data itself. Timing inaccuracy, known as
‘jitter’, is responsible for a wide range of subtle distortions. TAG
McLaren Audio uses its award-winning CD reproduction
technology to reduce jitter to its technical minimum by using a
very stable electronic clock, which is synchronized to the DAB
data to provide accurate timing.
The Digital Radio Upgrade has been tightly integrated into the
DPA32R
DAB
operating system for ease of use.

Adding the Digital Radio Module makes your DPA32R
DAB
a very
sensitive radio signal detector and, as such, it can pick up
interference from other nearby equipment. You may need to move
your DPA32R
DAB
or the interfering equipment if problems occur.
Connect a Digital Radio antenna to the socket marked
digital
radio (DAB) rf input (option)
on the rear of the DPA32R
DAB
. Best
results are achieved using a dedicated external Digital Radio
antenna, an indoor antenna may prove insufficient to receive
weak signals.
Press the power button in. The blue power LED will come on, the
display window will light up and the mute LED will illuminate
briefly whilst all voltages are stabilising.
Immediately after the power has stabilised, the DPA32R
DAB
will
begin scanning through all of the available Digital Radio
frequencies to find all stations. If Digital Radio (DAB) is selected
during this phase the upper line of the display will show
“SCANNING”
while the lower line of the display will show a
progress indication.
Press the
dab
key on the remote control or repeatedly the

button on the front panel until
