3 Installing and Connecting the Speaker
Use the mounting bracket to fasten the speaker at a suitable place .
For alignment, release the locking screws of the bracket, move the
speaker accordingly, and retighten the screws .
Power is supplied via the network connection (Power over Ethernet):
Connect the RJ45 jack to a network connection providing PoE (e . g .
PoE switch) . To configure the signal processor and to feed in audio
signals via a Dante network, connect the IT-400DT to an individual
computer, a local computer network or (via a router, for example) to a
large computer network . For outdoor installation, use the accessories
provided to make the connection cable weatherproof . For correct
configuration, knowledge in network technology is indispensable .
For integration into a Dante network, the speaker must at least
be connected to a Fast Ethernet switch (100 Mbits / s Ethernet) .
Even if the same connection jack of IT-400DT is used for DSP control
and for feeding in Dante signals, it is internally considered as two
separate Ethernet interfaces with different IP addresses .
Note: When the IP addresses in the local network are set manually, do not assign
the same address to both interfaces!
The DSP interface of IT-400DT is preset to automatic reception of an
IP address . If a DHCP server is available in the network connected,
the speaker will receive its address from the server . If an ordinary
Ethernet switch is used to connect the speaker to a computer and the
computer has also been set to automatic reception of an address and
if no DHCP server is available, the units will assign an address in the
range 169 .254 .0 .0 – 169 .254 .255 .255 to each other . This may take a
few minutes (depending on the computer system used) . To accelerate
connection without a DHCP server, assign an address in this range to
the computer and set the subnet mask to 255 .255 .0 .0 .
The network settings of the DSP interface can easily be changed
via the menu of the control program . In this menu, it is also possible
to assign a fixed IP address to the speaker (
☞
chapter 6 .11) .
Note:
If the DSP of IT-400DT is to be configured in large networks by means of
the control program, higher data volumes (e . g . when multiple Dante transmit
channels have been set as multicast flows) may lead to a failure of the control
connection . In this case, it may be necessary to connect a switch ahead of
IT-400DT which supports “IGMP Snooping” (IGMP = Internet Group Manage-
ment Protocol) . The switch can be configured to reduce the load on IT-400DT
so that the switch will only route multicast data to IT-400DT if the speaker has
requested these data .
The Dante interface of the speaker is also preset to automatic address
assignment; configuration via the program “Dante Controller” is
possible . For installation of this program please refer to chapter 4 .
