New Church Sound System Equalization Schedule

Posted by jdbsound on February 17, 2016

Notice to all Clients of JdB Sound Acoustics.

If you are in a new church building or you have done major renovations in your church, you will have to re-equalize the sound system many times in the first few years.  Here is the schedule you should follow.

  1. First-year – After the 1st month, 3rd month, 6th month, 9th month and 12th month
  2. The second-year – After the 4th month, 8th month and 12th month.
  3. Third-year – same as year 2
  4. The fourth-year – after the 6th and 12 months.
  5. Fifth-year – same as year 4
  6. Sixth to the seventh year, every 1 each.
  7. After that, do touchup to do loudspeaker decay drifts. (as speakers get older, the surrounds and cone can become stiffer and less compliant and that changes the frequency response of the speaker.  Equalization often compensates for mechanical aging.)

It takes up to ten years for most buildings to fully cure or longer depending on how much concrete and wood is used in the walls and floors.  For that reason, the humidity of the church becomes lower and lower as the church ages which also changes the sound of the worship space.

Also, depending on the climate area you are in, you should be re-equalizing your church sound system for each season.  more so the further you are from the equator.  If you have a digital processor or mixer, you can have presets for the room changes.

If your church is somewhat airtight and the HVAC system is properly designed to maintain temperature, even during worship services, the tuning cycle after 6 years can be relaxed for Displacement HVAC systems.
