Conference An internal matrix virtual partyline or busbar where many panels and
interfaces can talk onto or listen from the party line without talking to
themselves.
Destination A device such as an intercom panel, beltpack, or interface to which audio
signals are sent. The device from which audio signals are sent is called a
source.
Duplex All real-time communication between individuals talking face to face is full
duplex, meaning that they can both talk and listen simultaneously. The
Eclipse matrices provide full-duplex audio.
EHX EHX is the EclipseHX configuration software. EHX guides the operation
of the matrix circuit cards and connected panels.
Ethernet International standard which describes how information is transmitted
across a network. Provides for the efficient organization of network
components.
Fiber optic cable A fiber-optic cable consists of a glass core covered with a reflective
material called cladding and several layers of buffer coating to protect
the cable from the environment. A laser sends light pulses through the
glass core to the other end of the cable.
FreeSpeak Digital wireless communications product. Sold under the FreeSpeak
name in Europe and Asia and CellCom name in USA.
Full duplex Refers to transmission of signals in two directions simultaneously.
Hopping Refers to making a trunk connection through other matrices to a
destination matrix.
IFB Interruptible Foldback. The term foldback refers to sending program
audio / feed, or some other audio mix, back to announcers while they are
on the air. Doing so allows announcers to monitor themselves, other
announcers, videotapes of commercials, or some mix of sources, while
they on the air. This is typically found in television news and live
broadcast events.
Announcers typically wear a small ear piece so they can hear the
selected foldback audio mix. When a director wants to give directions to
an announcer on air, or to announce changes in the program, the director
must interrupt the foldback. To do this, the director uses a channel
specifically set up to interrupt the foldback audio.
Interface module A piece of electronic hardware designed to convert the four-wire signals
of a central matrix port to some other form of communication, such as 2-
wire partyline, telephone, etc. The interface module is connected to a
central matrix port. The external non-four-wire device is then connected
to the interface module.
i-Series The i-Series family of user panels includes two display stations, two non-
display stations, two expansion panels, and a level-control panel.
Eclipse also supports V-Series panels (see below).
ISO The ISO function, short for panel ISOlation, allows a panel operator to
call a destination, interrupting all the other audio paths for that
destination, and establish a private conversation. When the call is
completed the destination’s audio pathways are restored to their original
state before the interruption.
