Audio Alignment Level
The Audio Alignment radio buttons provide a means to select from EBU for standard
European transmissions or SMPTE, the standard for North American transmissions.
The ranges in dBm are shown below:
• EBU [0dBm = -18dBFS]
• SMPTE [+4dBm = -20dBFS]
Network Confi guration
IP Type
The Internet Protocol Type drop-down entry
fi
eld provides the choice of either Static or
DHCP [Dynamic Host Con
fi
guration Protocol] to con
fi
gure the
NewS
tream
transmitter.
Internet Protocol addresses are assigned to a host either at the time of booting, or
permanently, by
fi
xed con
fi
guration of its hardware or software. Fixed, or persistent
con
fi
guration uses a Static IP address.
DHCP is a network protocol used to con
fi
gure network devices to communicate on an
IP network. A DHCP client uses DHCP protocol to acquire con
fi
guration information,
such as an IP address, a default router and one or more DNS server addresses from
a DHCP server. The DHCP client then uses this information to con
fi
gure its host. Once
the con
fi
guration process is complete, the host is able to communicate on the Internet.
IP Address
The Internet Protocol Address that is displayed for the
NewS
tream
transmitter can
be modi
fi
ed. Click within the
fi
eld and type the value of the address that you want to
modify. Click
Save Changes
to retain the IP Address. When
NewS
tream
uses the
DHCP type, this
fi
eld displays the IP address received by the DHCP server.
Net Mask
A sub-network, or subnet, is a logical subdivision of an IP Network. All computers that
belong to a subnet are addressed with a common, identical, most-signi
fi
cant bit-group
in their IP address. This results in the logical division of an IP address into two
fi
elds: a
network or routing pre
fi
x and the rest
fi
eld or host identi
fi
er. The rest
fi
eld is an identi
fi
er
for a speci
fi
c host or network interface. Special gateways called routers exchange
traf
fi
c between sub-networks. Such routers constitute the logical or physical boundaries
between the subnets.
To change the Net Mask address, type the new value and click
Save
to retain the
Subnet Mask. When
NewS
tream
uses the DHCP type, this
fi
eld displays the Subnet
Mask received by the DHCP server.
