The following provides an insight into the routing of audio to and from remote locations when using the in-house production facilities at Creative Technology.
To support the requirement for remote contributions the intercom setup has 12 “slots” for remote contributors. Liaise with media colleagues to establish which slot a presenter will be on.
A Direct Out Prodigy MC acts as a MADI -DANTE converter.
Incoming audio
Incoming audio is de-embedded and sent to the Prodigy, converted to DANTE and routed to the ODIN using DANTE Controller.
Outgoing audio
Outgoing audio is routed via DANTE to the Prodigy where it is converted to MADI and embedded on the outgoing stream.
ODIN by RTS Intercoms is the comms matrix used in the facilities.

Interruptible Fold Back (IFB)
This is the intercom function where input audio is routed to a output destination, when the destination is called this programme audio is dimmed by a predefined amount, so that the call can be heard before restoring to its original level.
Mix Minus
The programme audio being sent to the destination is often referred to as a mix minus as it is the audio being broadcast or recorded, minus the microphone of the destination. This means the destination does not hear a delay of themselves. IFB is used to communicate with presenter in ears in a studio as well as remote contributors. Music played on a PA that dims in level when an announcement is made is also an example of IFB.
Building IFBs
When constructing IFBs the following components need to considered.
Input – The audio being routed to the destination. This is normally a mix minus and is picked up from the audio desk.
Output – The destination (presenter IEM Tx or remote slot.) The output can be sent directly and doesn’t need to go the audio mixing console.
Listen source- the pre fader mic at the destination. Including this in the construction of the IFB facilitates a two-way conversation.
When an IFB is added to a panel it is operated by enabling the listen on the IFB key in order to hear a reply when calling the IFB.
Routing audio using the IFB table
The IFB table can also be used to route audio between an input and output e.g. routing audio from Unity Intercom to a remote presenter. When using this function be sure to set the dim to the lowest amount (-1dB)
