John...I'm trying to find out what the forward or rearward adjustment with the bridge. It appears to me that the Faulkner Array has all the microphones in a parallel line? I saw this in the Review you have linked
Grace are about to launch a special bridge (pictured) for a central mic. With this arrangement, you’ll be able to have an M/S rig with omni outriggers, or use, for example, the triple ‘OCT’ arrangement of a pair of supercardioids and a middle cardioid eight centimetres forward of the others.
Are there any other uses for the bridge?
Since that one is already taken, we need a better name for this array!
I drilled and taped holes at the ends of the legs of a small folding lightstand base which provides this same spacing to use for that OCT arrangement on-stage it a few times. There was already a threaded hole at the end of one leg, I just did the same to the other two. Obviously that won't work aloft, but it's an easy mod for anyone using one of these stands. To use them I screw in studs and attach the shock mounts to them. Depending on which way I orient the ADK TL supermounts I can vary the capsule spacing from 12"-24" (30-64cm). That's what I used to run the 12" spaced parallel 8's last week.
