David v. R. Bowles array - classic

The suffix "classic" indicates that there is another version of this impressive collection.
I had the honor of exchanging thoughts with David himself. 
I asked him for permission to publish information about my rebuild of his array. We then discussed the technical aspects of his array.
As they say, I am standing on the shoulders of a giant.

This article is about the classic version of David's array. Due to Dolby Atmos becoming a reality, he added two more microphones to his array for greater compatibility. 
Further information is available in this article.

For now, we will focus on the classic version.

It is very flexible and can be adjusted to meet the needs of the sound engineer.
The distance "d" refers to the distance between the sides of the "button square" containing the omnidirectional microphones. 
The height of the microphones is half the distance "d" above the button square. 
The distance "d" is a linear correlation to the size of the sound source. This applies whether the sound source is a string quartet, a choir, or a symphonic orchestra.
The distance between the sound source and the array depends on parameters such as the venue and the "sweet spot," where the direct sound is slightly louder than the reflections.  In short, it's a matter of personal taste.

David also recommended some general guidelines about the height of the button square above the ground. For a string quartet, a good starting point is 2 m (~6.5 ft). For instruments and piano, start at 2.5 m (~8.2 ft). For orchestras and/or choirs, consider 3 m.
If the musicians are on a stage, use the stage level as your starting point. Add this height to the height of your array setup.
