Lobe Sensitivity

The edge of the blue coverage area for each channel represents where the sensitivity reaches -6 dB. Understanding how lobe sensitivity is displayed helps to:

  • Provide complete coverage in a space, either by adding lobes or changing the lobe width. This ensures the sensitivity is within 6 dB in all areas. It is acceptable for lobes to slightly overlap.
  • Ensure that spacing and isolation are adequate to reduce noise and maximize automatic mixing performance.
