I recently acquired a Nuemann PV46 preamp board, which I have just finished recapping. However, although I have searched high and low - I cannot find a schematic (apart from one which is of such poor quality resolution it isn"t usable) . Obviously I can trace out the inputs and outputs on the back connector and thus sort out implentation of phantom, phase and pad. but I need more information so I can figure out how to make the gain variable etc ( up to its maximum 46dB) etc. Can anyone here help me out please?
From what I can see from the bad quality schematic there are two resistors (same value) that set the maximum gain on a set basis - so possibly a dual gang pot could get me where in need to go - but I am not at all sure this is the right direction. This is the PV46, not the PV46a, b or c variant.
Thanks
