OVERVIEW OF FUNCTIONS
The AUDIO MODULE enables you to set up a multi-room audio system. The AUDIO MODULE, in
combination with Comelit Home automation system provides the option of controlling the audio
system by normal push button or by Comelit.
One AUDIO MODULE is used for each music zone.
These new models (art.20004503 and 20004504) have an analogic audio input in order to have the
possibility to connect an analogic audio source (hi-fi system or CD player) and listen music directly
from the loudspeakers of the system. Is possible to select the source from the webpage or use the
automatic switching from Media server source to the analogic input.
The AUDIO MODULE has to be connected to an existing hi-fi system or active loudspeaker (using
version without amplifier) or to the connected speakers using the integrated amplifier (using version
with amplifier).

AUDIO MODULE FUNCTIONAL PRINCIPLE
The AUDIOMODULE is based on the
Squeezebox
(
SQB
) Technology. This has a central
Server
(
Squeezebox Server respectively Logitech Media Server (LMS)
) to which several streaming
Clients
(
Squeezebox Client
) are connected.
The AUDIOMODULE not only has an integral SQB client, but also an integral SQB server. This means it
can be operated in both modes: “client mode” and “server-client mode”.
a)
Client mode:
In the client mode, the AUDIO MODULE acts as a streaming client and plays back music from
a remote Server. The AUDIO MODULE receives the audio files in digital form via the network
in data packets from the server and then converts these into an analogue music format so
that they can be played back by the speakers.
b)
Server-client mode:
In this mode the AUDIO MODULE acts simultaneously as an server and as a client. In other
words, the internal client accesses the internal server so that the device can also be used in
“Standalone” mode. In this mode, however, there are restrictions. It is only possible to
connect storage media with a total capacity of up to 32 GB, i.e. one USB stick with 32 GB or
two USB sticks of 16 GB each can be connected.
The SqueezeBox Server (The software was originally developed from Slim Devices) is also known
under the name Logitech Media Server (hereinafter referred to by the abbreviation „LMS“)
