Before I retired, I intended to remove the ppu's for our Tetramic from
their individual tubes and mount them all into a single 25mm (or there
abouts) tube, with a ST450 standard connector at one end and a mini-xlr
recessed into the other. The mic would then plug directly into this with a
degree of support thanks to the recessing, with rubber vibration isolation.
The larger diameter tube could then be mounted into one of the lovely
Rycote mounts that the ST450 uses. This system would get rid of most of
fragility problems of the existing system and help with any problems of rf
pickup due to having sections of unbalanced cable runs.
