1 Introduction
dLAN is an intelligent, secure technology that lets you set up a home network
easily, quickly and economically via your household power grid, without the
need for complex and expensive dedicated cabling. The available performance
and effort required for the installation also compares favorably to traditional
methods—dLAN technology now attains speeds you would expect from other
LAN technologies, and installing it is a breeze!
Introduction

Not only network signals can be conveniently transmitted via the electrical system using dLAN adapters. Audio signals with CD quality can be transmitted from
computers with a dLAN connection via electrical lines to suitable playback
devices. This allows you to turn your computer into your very own private broad
cast station and listen to your favorite music wherever a receptacle can be
found!

1.1 What exactly is dLAN?
dLAN (direct Local Area Network) uses the household power grid to transfer
data between computers equipped with suitable adapters and other network
components. As a result, any power outlet can be used as a network access
point. The data is modulated prior to transfer and sent as a signal via the elec
trical system in the house. State-of-the-art technology ensures that the power
and data networks do not interfere with one another. Networking via dLAN is
fast and secure. The data is encrypted using a key to prevent easy interception
by third parties.
1.2 The benefits of dLAN Audio extender
Our product allows you to transfer the sound output of your Windows PC in CD
quality (16 bit, 44.1 kHz stereo) via the electrical system to any room of your
house. For this purpose, a sound card driver is installed on your computer to
which the entire audio output of the computer is redirected. In this way, you do
not have to worry about individual settings of your favorite music player. Any
application that can output music via the built-in sound card also works with
this dLAN adapter.
RCA sockets as well as 3.5-mm jack socket are integrated for the audio output.
It allows you to easily and directly connect a stereo system or active loudspeaker.
This makes the adapter so flexible that it can be quickly taken to another room
where it can be plugged into an open receptacle—without reconfiguration!
Please do not use both connection types together at any time (RCA sockets and
jack sockets). Always connect your stereo system or your active loudspeakers
either to the RCA sockets or the jack socket.
-
Please note that dLAN devices such as the devolo dLAN duo (14 Mbps) and
devolo dLAN HS Ethernet (85 Mbps) with dLAN 200 AV devices (200 Mbps)
can be used on the same electrical system without interference, but they will not
be able to communicate directly with one another
1.3 Sample applications
The PC that is connected with the electrical system via a dLAN adapter sends its
audio signals to the dLAN Audio extender. It is connected with the input of a
stereo system in another room, e.g. via stereo RCA cable. On the PC, all audio
signals are redirected to the electrical system via the sound card driver. At the

target location, the adapter ensures a clean back transfer into sound signals CD
quality.
As an alternative, you can also connect the adapter directly with loudspeakers
that feature a built-in active amplifier via the built-in mini jack socket.

Never connect headphones directly with the adapter! It may damage the
device. The built-in sockets are intended for connecting active loudspeakers or stereo system.

2 Initial use
This chapter provides more information about the hardware and software as
well as the installation and startup of the adapter.
2.1 Package contents
Please take a moment to ensure that the contents of the package are complete
before starting with the installation of your adapter. You should have the follow
ing items:
쎲 Adapter
쎲 Cable
쑗 Stereo RCA cable
쑗 USB cable (starter kit only)
쑗 Network cable (starter kit only)
쎲 Hard copy of installation guide
쎲 CD-ROM with software and online documentation

2.2 Displays and connections
2.2.1 Control indicators (LEDs)
The current status of the adapter is shown via control indicators (LEDs) on the
outside of the housing.
Operation: lit continuously when the adapter is connected to the electrical system.
dLAN: lit continuously when a connection exists to other dLAN adapters; flashes
when data is being sent or received via electrical lines.
LAN connection: lit continuously when a connection with the network exists;
flashes when data is being sent or received in the LAN.
2.2.2 Ports
The product is very easy to handle. The device has very few ports:
쎲 The AC plug connects the adapter to your electrical system.
쎲 The device is connected with your stereo system or your active loudspeakers
via the two RCA sockets (red=right stereo channel, white=left stereo chan
nel).
쎲 As an alternative, the 3.5-mm jack socket (stereo) can be used for the
connection.

2.3 Connecting the adapter
2.3.1 Connection to the electrical system
To connect the adapter, plug it into an open receptacle at the desired installation location. Ensure that the adapter is fully inserted in the outlet.
If possible, do not plug the adapter into a power strip. This may impair the transmission of the dLAN signals. A free wall outlet is preferable.
2.3.2 Connecting the audio cable
Next, connect either the two RCA sockets or the jack socket using a suitable
cable with an open input of your stereo system or active loudspeakers.
For stereo systems, it is essential to check first which input is still available. Do
not confuse inputs with outputs (the latter are frequently labeled with "PLAY" or
devolo dLAN Audio extender
|

Initial use
|
"Output"). Avoid the PHONO input. It is specifically designed for connecting a
record player or turntable. The result would be a poor sound quality.
Jack plug
RCA plug
The figure shows the two connection types jack plug (top) and RCA (bottom).
Any audio cable can be used for the audio connection, e.g. 2x RCA (stereo) to
2x RCA (stereo), 3.5 mm jack plug to 2x RCA (stereo) or 3.5 mm jack plug to 3.5
mm jack plug. If you are using an RCA cable, ensure that the red and white con
nectors are inserted in the sockets with the same color. In very rare cases, the
connector of such a cable may also be black. That would correspond to the white
color.
Please do not use both connection types together at any time (RCA sockets and
jack sockets). Always connect your stereo system or your active loudspeakers
either to the RCA sockets or the jack socket!
-
Never connect headphones directly with the adapter! It may damage the
device. The built-in sockets are intended for connecting active loudspeakers or stereo system.
