Wireless in-ear or “personal” monitors can be used in a variety of ways in
the broadcast or video production environment. Reporters in the field can
hear questions and answers from the broadcast studio; the narrator of a
video program can listen to a prerecorded script while simultaneously recit-
ing it (sometimes called an “ear prompter”); an actor can hear stereo music
playback while singing along; a presenter can hear questions picked up by
audience microphones. In many applications, the director can cut in to give
instructions; the monitor signal is then called Interruptible Foldback, or IFB.
Tips on Using Wireless Systems: When using wireless microphone
systems, try to keep the distance from transmitter to receiver as short as
possible. Always do a “walkaround” before the event begins; that is, listen
to the system while walking around the anticipated performance area. If
dropouts occur, try moving the receiver a few feet and repeat the
walkaround. If possible, the walkaround should be done at the same time of
day as the event, to expose nearby users of the frequencies on which you
intend to operate. When using belt-pack type transmitters, be sure that the
antenna cable is hanging straight. If it is coiled up in the wearer’s pocket,
transmission distance will be significantly reduced. With handheld
transmitters that have an external antenna, discourage users from holding
their hand over the antenna, which will reduce transmission range and
increase the likelihood of dropouts.
