Calibration Setup

Microphone Placement

  • Get your calibration kit and set up the mic stands.
  • If the seats are not at 1/2 or 1/4 length and width positions, set them up in random positions within the seating area.
  • Place one mic at the MLP (main listening position)
  • Avoid placing any mic in a null which are located at 1/2 or 1/4 length and width positions.
  • Mix up the height of each mic; avoid placing any two mics at the same height.
  • Try to keep all mics away from speakers.
  • If the seats are in nulls, focus mic placement on the head locations.
  • Try to place the mics to avoid blocking the seat from being sat in.
