AB-120 Announcer Console
IFB: The term means “Interrupt Fold Back.” A fold-back is a monitor system that allows, for
example, talent to hear their voices or musicians to hear their voices and instruments on stage.
IFB (program interrupt) disconnects the audio source while the talk button on the main station
is pushed.
ISO: A private conversation path. An ISO channel allows one to simply push a button and
transfer themselves and the person they wish to speak with to an isolated channel.
Linking: Linking ties separate channels into one single party line.
Main Station: This is a product that includes both the ability to communicate with multiple
channels without connecting them together, and to power all the stations connected to these
channels.
Master Station: A remote station which needs AC power to operate.
Multi-Channel: More than one channel.
Party Line (P.L.): Intercom system in which all people talking on the system can talk or listen to
each other simultaneously. Also called conferencing.
Point to Point: One path to one person.
Program: Audio source that is fed into the intercom channels.
Program Interrupt: Disconnects the audio source while the talk button on the main station is
pushed (IFB).
Remote Mic Kill (RMK): The ability for certain main stations to shut off all microphones on
beltpacks in a system.
Remote Station: Like the beltpack, this would be any of the products connected to the
intercom line that allow duplex or half-duplex conversation, but do not contain a power supply.
Sidetone: This is your own voice heard in your earphone as you are speaking.
Stage Announce (SA): Redirects output of the main station's microphone to an external
destination (such as a PA system).
Station: A station is connected to one or more channels. For example, if you have six people
who need to hear one director, you have a seven-station single-channel need. If the same
director needs to speak privately to any one of the six, add a second channel. You now have a
seven-station, two-channel system.
“Switchcraft
®
-style” 6-pin XLR: Unlike most regular XLR connectors, there are two different
versions of 6-pin XLR connectors. The “Switchcraft-style” and the European DIN style. Beware
that the “Switchcraft-style” and DIN based versions are not compatible. When selecting
Neutrik 6-pin XLR connectors ensure they are “Switchcraft-style” with the -S suffix to the part
number for compatibility with Clear-Com products.
