IFB CONFIGURATION

One of five CellCom basestation inputs can be defined as a source for

an IFB. These inputs are the Program Input and the four 4-Wire ports.

All the 4-Wire ports, party line channels, beltpacks, wireless party lines

and stage output can be defined as IFB destinations.

Up to ten IFB key configurations can be set up that group together an

IFB source and a number of IFB destinations and set the dimming level

for that IFB key configuration.

Table 4-4: IFB Key Configurations

An IFB talk is a panel or beltpack with a key set up to talk to the IFB

key configuration. Whenever an IFB talk key is pressed the audio from

the IFB source to the IFB destinations configured in the IFB key

configuration is dimmed by the set amount and the audio from the IFB

talk is heard by all the IFB destinations set up in that IFB key

configuration.
