IFB

IFB Systems

Directors, script supervisors, clients and agencies need to hear the dialogue while shooting. An IFB system sends the set mix to wireless receivers, frequency-coordinated with microphones and communications so nothing interferes.

What your production gains

  • Everyone hears the take

    The director and clients follow the dialogue in real time without depending on a wired monitor.

  • Integrated with RF coordination

    IFB frequencies are calculated together with the microphones to avoid intermodulation.

  • Mixes per listener

    A different mix can be sent to the director, client or script supervisor when the project requires it.

Frequently asked questions

Does IFB require RF coordination?

Yes. It's one more transmitter on set and must coexist with microphones and communications without causing interference.
