ctboita Posted November 18, 2021 Report Share Posted November 18, 2021 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. Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted November 19, 2021 Report Share Posted November 19, 2021 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.
