Drawbacks include a less optimized lighting which needs toprovide a
compromise for all camera angles and less flexibility in putting the
necessary equipment on scene, such as microphone booms and lighting
rigs. These can be efficiently hidden from just one camera butcan be
more complicated to set up and their placement may be inferior in a
multiple-camera setup.

A Boom operator is an assistant of the production sound mixer . The
principal responsibility of the boom operator is microphone placement,
usually using a boom pole (or "fishpole") with a microphone attached
to the end, their aim being to hold the microphone as close to the
actors or action as possible without allowing the microphone or boom
to enter the camera's frame. Often in television studios,the boom
operator will use a"fisher boom" which is a more intricate and
specialized piece of equipment that the operator stands on, and that
allows precisecontrol of the microphone at a greater distance from the
actors. He or she will also attach wirelessmicrophones to persons
whose voice requires recording. Boom poles are usually manufactured
from several lengths of aluminium or carbon fibre tubing,allowing the
boom to be extended and collapsed as the situation requires. Some
poles have a microphone cable routed through the inside of the pole,
which may be a regular cable protruding at the bottom end, or a coiled
cable that can extend with the pole, connecting to a socket at the
base that the operator plugs their microphone cable into. The ideal
boom pole is lightweight and strong, supporting the weight of the
microphone on the end while adding as little weight as possible
Wireless microphone
radio microphone , it has a small, battery-powered radio transmitter
in the microphone body, which transmits the audio signal from the
microphone by radio waves to a nearby receiver unit, which recovers
the audio.
with the aid of an antenna , produces radiowaves . The transmitter
itself generates a radio frequency alternating current , which is
applied to the antenna.
Radio frequency ( RF ) is a rate of oscillation in the range of about
3 kHz to 300 GHz , which corresponds to the frequency of radio waves
, and the alternating currents which carry radio signals.RF
