Network Address System
Network Public Address System
Network Public Address System
23
Description:
In the connection diagram as shown above, all devices directly connected to the network must be connected
to the network via network switches. Each device connected to the network requires a corresponding IP
address.
The PA device and various regular devices (audio source, microphone, monitoring speaker, etc.) are corresponded
to each other. Please refer to the diagrams of front panel and rear panel for information. In order to ensure fast
data transmission on the entire local area network, please connect the devices to network as shown below (see
above figure (previous page)).
It is recommended that the system runs on a 100Mb or faster local area network (a local area network is also
known as LAN or Ethernet). If there are a small number of terminals connected to the PA system (less than 20),
the system may operate on a 10Mb LAN, with slightly negative influence on performance. Better performance can
be realized in a network with Star-Topology than in a bus topology network. It is NOT recommended to establish
the network by using network hubs (HUB). (HUB provides the same functions as a network switch, but the speed
is limited.)
In most cases, the PA host is firstly connected to uplink port of an Ethernet switch, and other ports of the Ethernet
switch are linked to the terminals or UPLINK ports of other switches in the Ethernet. Other switches may connect
more terminals or UPLINK ports of even more switches. In this way, the network ports are extended.
Refer to the following picture for common network cables and ports used in Ethernet: (taking 100Mb Ethernet as
an example. The picture is only for reference and DSPPA will not provide any network equipment. If required,
please consult your network equipment supplier.)
