During your tour as a television broadcaster, you

The most flexible mobile microphone is one that is
attached to a microphone boom. A boom, in its simplest

the operator can rotate the microphone for directional
Another advantage of the boom is its mobility on
the set. The boom operator can move the entire boom
assembly from location to location and follow sound
sources without an interruption to sound pickup. The
giraffe boom (fig. 14-20) is suited perfectly for this task.
