5 Setup

5.1 Rack installation

The unit can be installed into a rack (483 mm /19") by means of the mounting brackets. The device requires
1 unit and can be fixed with four screws M6 in the rack. You may remove the mounting brackets to use the
unit as a desktop device
▪ When mounting the unit into the rack, please make sure that there is enough space around the device so
that the heated air can be passed on. Steady overheating will damage your receiver.
▪ When establishing the first wireless connection, the unit should be placed as close as possible to the router
to ensure a flawless WiFi signal. Afterwards, the Internet radio can be placed within the range of the WiFi
signal.

5.2 Making the connections

Danger to Life!
High voltage at terminals when using PA systems. Installation by skilled personnel only! Turn off receiver
before connecting.
(1) Four audio units with line level (e.g. CD player, tuner, mixer) can be connected to the stereo RCA jacks
LINE INPUT 1 to 4. Always connect the left channel to the white jack and the right channel to the red
jack.
(2) An additional audio unit with line level can be connected to the 3.5 mm jack on the front panel (e.g. MP3
player, smartphone, notebook). The radio will be muted when this jack is connected.
(3) Use the MIC IN jack to connect a dynamic microphone via an XLR or 6.3 mm jack plug.
(4) In stereo mode, the receiver can operate two speakers or two speaker groups. The receiver is able to
deliver 2 x 460 watts for 4 Ω speakers and 2 x 240 watts for 8 Ω speakers. Use the red terminals
(positive contact) and black terminals (negative contact) for connecting the speakers.
▪ For double output power it is possible to switch over to bridge mode and operate one speaker or one
speaker group. In this case, use the two red terminals for the connection.
▪ Always use sufficiently dimensioned cables (min. 2.5 mm²). When interconnecting several speakers, it is
especially important to consider the correct connection to positive and negative contacts and that the
minimum total impedance is 4 Ω for stereo and 8 Ω for bridge operation. Please refer to skilled personnel
if you are not familiar with the connection of several speakers.
(5) Alternatively, it is possible to operate one 100V PA speaker or speaker group with 260 watts. In this
case, use the two red terminals for the connection.
(6) For connection to units with line level (e.g. recording unit or additional amplifier) the stereo RCA output
OUTPUT can be used. The digital SPDIF or Toslink outputs carry the signal of the Internet radio; you
may use these if your audio device has a corresponding digital input.
▪ The line output is not amplified. Therefore, the volume is adjusted via the following device. However, you
can adjust the playback volume of the Internet radio with the volume control on the Internet radio.
(7) A router is required to connect to the Internet. Connect the Internet radio to the router via the LAN socket
using a network cable.
▪ Configuration is not normally necessary when connecting to the network via a network cable if the DHCP
function is activated on the router.
(8) For the WiFi radio connection, screw the enclosed rod antenna onto the WLAN ANTENNA socket. Point
the antenna vertically for operation.
(9) For FM and DAB reception connect an appropriate antenna to the Antenna DAB/FM socket. If reception
conditions are good, the enclosed wire antenna can also be used. In this case, place the device near a
window if possible and unroll the antenna.
(10) Finally connect the receiver to a mains outlet with the mains cable.
