Contrary to the previous comment, this works perfectly. I asked SRS to design this mount and was probably the first to own one. It works fine. If the back of the mic is flush with the back of the arm on the mount, then capsules will be exactly 20cm apart (DIN) or 17cm apart (ORTF). (tgoebel: you say "correct mic *base* distance"...you do realize that the distance is the capsule near the front of the mic, right?
