ISO The ISO function, short for panel ISOlation, allows a panel
operator to call a destination and interrupt all of that destination’s
other audio paths and establish a private conversation. When the
call is completed the destination’s audio pathways are restored to
their original state before the interruption.
Keygroup KeyGroups provide a way of assigning a label to multiple panels
simultaneously even within a networked matrix system. Once the
KeyGroups have been defined using ECS, all the keys within a
KeyGroup can be changed with a single assignment in Production
Maestro (Pro mode only).
Label A label is an alphanumeric name of up to five characters that
identifies a source, destination, or control function accessed by an
intercom panel. Labels appear in the displays of the intercom
panel.
Labels can identify panels, ports interfaced to other external
equipment, fixed groups, party lines, and special control functions.
MADI Multichannel Audio Digital Interface. The MADI or AES10
electronic communications protocol defines the data format and
electrical characteristics of an interface carrying multiple channels
of digital audio.
Multiplexing The process by which two or more signals are transmitted over a
single communications channel. Examples include time division
and wavelength division multiplexing.
Non-volatile Memory Data stored in the CPU’s firmware (ROM) that is not lost when the
power is turned off.
Palette The port, keyGroup and Monitor selection screen in Production
Maestro Pro.
Panel Any intelligent intercom device connected to the rear-panel analog
ports of the central matrix. This term does not refer to devices
connected through interface modules.
Partyline A wired shared communication system based on a single
screened pair of wires. See the Encore range. Matrix requires the
CCI-22 to interface to it.
Port Any of the input/output connections (RJ-45 connectors) on the
back panel of the central matrix. These connectors and the
attached cables connect the central matrix to remote intercom
devices. The term port emphasizes that the connection is a portal
between the central matrix and the remote intercom devices.
Program Any separate audio source that is fed into the intercom channels.
In television applications, for example, the program audio is the
audio that is broadcast on air.
Rack Unit (RU) Standardized unit of mounting space on a rack panel. Each rack
unit is 1.75 inches (44.45 mm) of vertical mounting space.
Therefore 1 RU is 1.75 inches (44.45 mm) of vertical mounting
space, 2 RU is 3.5 inches (88.9 mm), 3 RU is 5.25 inches
(133.35mm), and so on.
