Just a reminder that if you typically like DIN but your PAS arrangement at any particular venue has you using less angle between mics, which it will in most situations, it will be advantageous to compensate for the narrower angle between mics by introducing more spacing between them. The moral to the story is this: If you use PAS a lot, figure out a way of achieving adjustable mic spacing with your mounting setup which can place the mic capsules wider than a typical 7” to 12" bar.
It's that increased spacing part of optimizing a PAS setup which most people either neglect entirely or compromise on. Some may be unaware of the basic relationship, but others here who are aware of the relationship are constrained by the limitations of their mounting system and/or simply unsure of how much additional distance between mics is appropriate.
About a year ago I started a thread about that, which went into far more technical detail than most here probably care to immerse themselves in. It was a good discussion, but the complexity was unfortunate in a way, because my primary motivation was to derive simplified tables which easily indicate the optimal microphone spacing for whatever PAS mic angle the user ends up with.
Here's that thread-

The idea is that if you like what you hear from a DIN setup when that is an appropriate choice, but wish to use PAS instead in a compromised situation, you can get a recording with some similar attributes by first pointing your mics at the stacks (or just outside them) and estimating the resulting angle between the mics, then checking the table to find the appropriate spacing for that microphone angle.
You really only need the first two columns. The first column indicates the angle between mics and the second indicates the suggested spacing to arrive at the same recording angle as a DIN setup. Note that the mic spacing indicated in the second column is specified in centimeters. For most PAS situations where the angle between mics is narrower than 90 degrees, you would be referring to the bottom half of the table. DIN is in the middle-
