Phase Shift Exploited in AFILS to ‘shift’ the frequency relative phase of the two loop output
signals between two loop outputs by 90° in order that two separate inductive loops
can be driven with the same signal without causing interference to the magnetic
fields produced. Using this method an even magnetic field strength can be
created throughout the listening plane (ear height) in large areas or building that
utilise metal in their construction .
Phantom Power A 12V microphone power source that uses the existing microphone connections
on the XLR socket. See IEC 61938.
QoS Quality of Service (QoS) refers to the capability of a network to provide better
service to selected network traffic over various technologies, including Frame
Relay, Asynchronous Transfer Mode (ATM), Ethernet and 802.1 networks, and IP-
routed networks .
Redundancy Term used in network audio to provide a secondary, identical, isolated network
with the same data as the primary . In the event of a failure in the primary network
the secondary network is automatically activated .
Router A network device that forwards data packets from one network to another . Based
on the address of the destination network in the incoming packet and an internal
routing table, the router determines which port (line) to send out the packet (ports
typically connect to Ethernet cables).
Switch
A network switch (also called switching hub, bridging hub, or MAC bridge) is a
networking device that connects multiple devices together on a computer network,
by using packet switching to receive, process and forward data to the destination
device .
Subnet Mask
A mask used to determine what ‘subnet’ an IP address belongs to. Defined by the
Router .
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic
communication language or protocol of the Internet . It can also be used as a
communications protocol in a private network (either an intranet or an extranet).
Unicast
Unicast transmission is the sending of messages to a single network destination
identified by a unique address. The default method used by Dante.
USB
The ‘Universal Serial Bus’ is an industry that defines the cables, connectors and
communications protocols used in a bus for connection, communication, and
power supply between electronic devices . Utilised in the AFIL Driver to provide
power to a LAN Router or for connecting a USB drive to update firmware.
WAN Wide area network (WAN) cover a large geographic distance.
XLR XLR connectors are a style of electrical connector, primarily found on professional
audio, equipment used to transmit a balanced mono audio signal or unbalanced
stereo signal .
