Not exactly a DIY, but rather can someone else DIY for me? I have a few Countryman B6 lav mics that I'd like to permanently convert from XLR to 3.5mm mini so I can use them with my Sennheiser AVX transmitters. Is this possible? If so, can anyone do this for me or do you have a recommendation of where I should them to? Thanks for any help.

Assuming Sennheiser AVX transmitters use the same wiring configuration as the G2, 3, 4, a 3.5mm TRS plug can be soldered on replacing the XLR power supply/adapter. The body pack Tx will supply the needed bias voltage. The audio and bias are connected to the plug's Tip terminal, the ground/shield are connected to the plug's Ring and Sleeve.
btw, Countryman's wiring guide recommends a 6.8k resistor between the plug's tip and sleeve terminals.
