rotary function dial and 4 tactile pushbuttons. The controls and indicators on the front panel
of the unit are guaranteeing an intuitive and user friendly operation, allowing hassle free
operation and configuration to even unexperienced users. Information such as internet radio
station information is are indicated.
It synchronizes with the database which contains over 30.000 channels, allowing selection
on different criteria such as genre, location, language, ... while custom streams can also be
added to a preference list up to 100 entries. The signal output level as well as the systems IP
settings and other advanced network settings are user configurable, allowing implementation
to any audio system connected to home, office or enterprise data networks.
The input connection is implemented by an RJ45 type connector with indicator LED’s, allowing

Additional information
IP Basics
Many AUDAC products are controllable by Ethernet. The Ethernet connection which is used
on the AUDAC products is TCP/IP based, like 99% of the computer networks. There are
some basics which you need to know to successfully make a TCP/IP Ethernet connection.
The data in TCP/IP networks is always send in packages, all these packages must be delivered
at an unique address, just like the mailman delivers mail at your home mailbox. In TCP/IP
networks, this address is called the “IP address”. The IP address is always a number in the
following format “192.168.000.001”. As you can see, this address consists of 4 separate
numbers ranging from “000” to “255”.
In simple terms, only the latest number of an IP address can be different within a network,
so there is a maximum of 254 unique addresses within a network, ranging from “xxx.
xxx.xxx.001” to “xxx.xxx.xxx.254”. The first three numbers must be the same to make
communication between several devices possible, else the devices can not communicate
with each other.
Example:
Device 1: IP address: 192.168.000.001
Device 2: IP address: 192.168.000.002
Device 3: IP address: 192.168.001.003
In this example, Device 1 can communicate with Device 2, but not with Device 3, because
the first three numbers must be the same. These first three parts are called the “IP range”,
so the devices must be in the same “IP range” to communicate with each other.
The “IP range” of home and office networks are defined by the network administrator, this
means that the IP range of your home or office network can be different from another network.
AUDAC products have the following IP address as default: “192.168.0.xxx”, this means
the standard IP range of AUDAC products is “192.168.000.xxx”. If your network is using a
different IP range, the AUDAC products will not be accessible from your network. You can
change the IP address of the AUDAC products to make them work properly in your network.
This can be done in the settings menu, and is described extensively in the “Settings” chapter
of this user manual.
Ask your network administrator for help if you are not familiar with networks.
Summary
- All devices must have an unique IP address
- All devices must be within the same IP range
