How to Use This Calculator
  1. Enter room volume (cu ft) — multiply length × width × height of the worship space.
  2. Set seating capacity and worship style: 1=Traditional, 2=Blended, 3=Contemporary.
  3. Set Live streaming (0=No, 1=Yes) to include streaming equipment in the budget.
  4. Review Amplifier power (watts), Main speakers, Mixer channels, and Wireless microphones for equipment specification.
  5. Use Target SPL (dB) and Total budget ($) to get quotes from AV contractors.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Room volume (cu ft) = 40000, Seating capacity = 300, Worship style (1-3) = 2, Live streaming (0/1) = 1 = 4 input(s) provided
  2. Calculate Amplifier power
    Amplifier power
    1500 = 1500
  3. Calculate Main speakers
    Main speakers
    3 = 3
  4. Calculate Mixer channels
    Mixer channels
    24 = 24
