corresponds to all relevant directives of the
EU and is therefore marked with
.
G
The unit is suitable for indoor use only. Protect it against dripping water and splash
water, high air humidity and heat (admissible ambient temperature range:
0–40°C
).
G
Do not place any vessel filled with liquid on
the unit, e. g. a drinking glass.
G
Immediately disconnect the mains plug
from the socket
1. if the amplifier, the power supply unit or
the mains cable is visibly damaged,
2. if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3. if malfunctions occur.
In any case the unit must be repaired by
skilled personnel.
G
Never pull the mains cable to disconnect

material damage will be accepted if the unit
is used for other purposes than originally

way.
4 Installation
1) Place the amplifier at a suitable location
and, if required, fasten it using screws.
2) Insert the antenna (1) into the jack ANT (2);
then tighten the antenna and place it in a
vertical position.
3) Connect the speakers to the jacks (5)
[Right OUT for the right channel, LEFT
OUT for the left channel].
To obtain the highest output power,
connect speakers with an impedance of
4 Ω. It is also possible to connect speakers
with higher impedance; this, however, will
reduce the output power accordingly.
4) Finally, connect the power supply unit to
the jack DC IN (3) and the mains plug to a
mains socket (230 V~ / 50Hz). The amplifier will be switched on.
When the amplifier is not used for a
longer period of time, disconnect the
power supply unit from the mains socket to
save power.
5 Operation
1) At the player (smartphone, tablet PC, computer, etc.), switch on the WLAN function.
2) Establish the connection to the amplifier.
On the player, the amplifier will be indicated by “WiFi-HiFi_” and four digits. Each
amplifier has a digit sequence of its own so
that it is possible to select individual amplifiers when multiple amplifiers are used.
3) Start the DLNA player.
5.1 Configuring the AKB-90WIFI
The amplifier can be configured by means of
the integrated web server. Enter the IP
address of the AKB-90WIFI in an Internet
browser: 10.10.10.254
It is, for example, possible to change the
shown name “WiFi-HiFi_xxxx” and the menu
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not
harmful to the environment.
WARNING The power supply unit uses dan-
gerous mains voltage. Leave
servicing to skilled personnel
only. Inexpert handling of the
unit may result in electric shock.
