hear their voices and instruments on stage. IFB (program interrupt)
disconnects the program 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 where 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.
Termin ation: Passive network that is connected in each channel, usually on
the power supply or main station.
