adapter for various antenna connector optional
This
DAB interface
allows the connection of a DAB/DAB +
radio to the original car antenna
. The active antenna
splitter splits the signal of
the original FM car antenna
for FM and DAB / DAB + receiver. Perfect for the easy
installation of a DAB receiver. There
is no need of complicated replacing
the antenna.
The
DAB antenna splitter
provides amplified signal from the car antenna for the FM and the DAB / DAB + input of
the radio. The normal losses from conventional antenna splitters are balanced by the
integrated amplifier
. The
new
technique
achieved mostly even an
improved FM reception
.
Connection:
Disconnect antenna cable from radio and
plug
DAB interface
between
. Plug the each
antenna connector to FM and DAB input from
car radio.
The integrated antenna amplifier receives its
operating voltage
through the
phantom
power
of radio. (Phantom power: 12V voltage
output from the antenna connector on the radio,
for use with active antenna)
If your radio has
no phantom power
you have
to connect the operating voltage with the red
wire.
If possible, using for 12V power supply
the
"switching antenna output"
or
“amplifier
remote”
on the radio to avoid
discharging the
battery and interference
with receiving
causes trough the electrical system. Does the
radio do not have these connections using
ignition voltage.
If you are
not sure
if the radio provides
phantom power, you simply test the function of
the DAB splitter. Is the FM radio reception
much worse than before, the red wire must be connected to voltage as described.
It is no problem to connect the external voltage even thought the supplying phantom power of the radio. The active
DAB splitter has also the function of
a phantom power supply
(supply voltage for active antenna). You
don’t need
a
separate phantom power adapter.
Note for combination with active antennas:
its no possible to use the DAB splitter if the active antenna has a
frequency band filter. The DAB frequency must pass on the amplifier of the antenna.
More hint´s:
Look for a tight fit of the connectors and try to avoid tension during installation the radio.
The quality of the radio reception is affected by many factors (e.g. local conditions, antenna or cable laying).
Do not position the DAB splitter near charging connectors, e.g. navigation charger cable.
