Figure  14-19.—Microphone  polar  patterns. POLAR PATTERNS The pickup, or polar pattern, of a microphone is the shape of the area around it where it picks up sounds with maximum fidelity and volume. Nearly all microphones can pick up sounds from areas outside the ideal pattern, but  their  quality  is  not  as  good.  For  best  results,  the sound  source  should  be  within  the  pickup  pattern, generating enough volume to allow the audio switcher to keep the volume control pot at a minimal level. Microphones   are   classified   according   to   the following three basic polar patterns: l   Unidirectional l   Omnidirectional l   Bidirectional Unidirectional The  unidirectional  microphone  picks  up  sound  from only  one  direction.  Because  of  this  characteristic,  the unidirectional microphone is used most frequently for television work. It is used by aiming it in the direction of the sound source being recorded. One advantage to the  unidirectional  microphone  is  its  ability  to  reject unwanted sounds at the side and rear of the direction the microphone  is  aimed. Omnidirectional The   omnidirectional   (or   nondirectional)   micro- phone is live in all directions. This type of microphone has sensitivity characteristics in which sound is picked up in a 360-degree radius. The use of this microphone in television production is limited; however, in certain situations,  you  may  use  it  to  create  a  specific  sound presence. One example is recording crowd noise for a sports  production. Bidirectional As the name implies, the bidirectional microphone picks   up   sound   in   two   directions.   This   type   of microphone   is   used   primarily   in   the   broadcast   or recording  studio.  It  is  also  used  for  critical  sound reinforcement   applications   in   which   front   and   rear 14-20
