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.

Termination:

 Passive network that is connected in each channel, usually on 

the power supply or main station.
