Hi Everyone,
Earlier this year I decided to begin working on converting a couple of defective AKG C480B bodies to the Neumann KM84 circuit. This project went on hold for a while, but I recently started to work on it and there's something I'm not sure of on the KM84 schematic.
R11 and R12 are the resistors that are connected in series with XLR pins 2 and 3 and are 47 Ohms. My interpretation is that those resistors seem to have jumpers on them that, according to the schematic, are removed for certain models of mic, but stay in place for the KM84.
So ... for R11 and R12, should I use these resistors or bypass them for the KM84 circuit?
I should have the pcbs populated soon so I'll post pictures shortly.
Thanks,
Gord
