3 Safety Notes
The units (amplifier and power supply unit) cor-
respond to all relevant directives of the EU and
are therefore marked with .
WARNING
The power supply unit uses dan-
gerous mains voltage . Leave ser-
vicing to skilled personnel only .
Inexpert handling of the unit
may result in electric shock .
•
The units are suitable for indoor use only . Pro-
tect them against dripping water, splash water
and high air humidity . The admissible ambient
temperature range is 0 – 40 °C .
•
Do not place any vessels filled with liquid, e . g .
drinking glasses on the units .
•
Do not operate the units and immediately dis-
connect the mains plug of the power supply
unit from the mains socket if
1 . there is visible damage to one of the units
or to the mains cable
2 . a defect might have occurred after a drop
or similar accident,
3 . malfunctions occur .
The units must in any case be repaired by
skilled personnel .
•
Never pull the mains cable to disconnect the
mains plug from the mains socket, always
seize the plug .
•
For cleaning only use a dry, soft cloth; never
use water or chemicals .
•
No guarantee claims for the units and no
liability for any resulting personal damage or
material damage will be accepted if the units
are used for other purposes than originally
intended, if they are not correctly connect-
ed or operated, or if they are not repaired in
an expert way . Likewise, no liability will be
accepted for data loss caused by a defect or
operating errors and for any consequential
damage of this data loss .
If the units are to be put out of oper-
ation definitively, take them to a local
recycling plant for a disposal which is
not harmful to the environment .
4 Installing the Amplifier
1) Find a suitable location for the amplifier
and set it up; if necessary, screw on the two
mounting brackets (1) .
2) Insert the antenna (11) into the jack ANTEN-
NA (13); then tighten the antenna and place
it in a vertical position .
3) Connect the speakers to the jacks RIGHT
OUT and LEFT OUT (12) . To obtain the high-
est output power, connect speakers with
an impedance of 4 Ω . It is also possible to
connect speakers with a higher impedance;
this, however, will reduce the output power
accordingly .
4) If required, connect the output of a stereo
audio source with line level (e . g . CD player,
tuner, mixer etc .) to the 3 .5 mm jack AUX (7) .
5) To replay audio files from a USB flash drive,
connect the USB flash drive to the USB
port (6) .
Important:
The AKB-40WIFI will store a playlist file
on the USB flash drive . To avoid any data loss, always
stop the replay before removing the USB flash drive .
6) Use the RJ45 jack NETWORK (5) for Ethernet
connection to a local network .
7) Connect the power supply unit to the jack
18 V
⎓
(8) and the mains plug to a mains
socket (230 V/ 50 Hz) . The amplifier will be
switched on . To prevent unnecessary power
consumption, disconnect the power supply
unit from the mains if the amplifier is not
used for a longer period of time .
4.1 Network connection
Via its WLAN functionality, the AKB-40WIFI can
be integrated as a client into an existing net-
work or directly connected as an independent
access point . Both access types can be used at
the same time . Cable connection via Ethernet to
an existing network is also supported .
4.1.1 Amplifier as access point
The AKB-40WIFI can be used as an independ-
ent access point to create a WLAN . This is the
easiest way to replay, via the AKB-40WIFI,
audio files with a DLNA player on a mobile
device . In the list of the other WLAN units,
the amplifier will appear with the SSID “WIFI-
Speaker_xxxx”(xxxx = number) .
