Hi guys!
My first post here so my problem will probably sound very basic but I'm just starting out: I got a Shure 55SH Series II dynamic microphone that generates no output.
Here are a few pics of the open mic:
CAPSULE
SWITCH
XLR PLUG
FWIW, a schematic is available from Shure's website here: http://www.shure.com/idc/groups/tech_pubs/@global_managed/documents/webcontent/us_pro_55sh_series2_ug.pdf
A few questions: what does each of these wires coming out of the capsule do? The blue wire goes to pin 1 of the XLR plug, the black to 2 and the yellow to 3. Black and yellow also pass through the switch. Am I right to assume these last two are positive and negative and the blue some sort of ground wire?
So far I have tested continuity and resistance for each path. The weird thing is if I put one prob on the black wire next to the capsule and the other probe on pin 3 of the XLR plug (yellow wire), there is continuity. Is this normal or does it mean there's a point of contact between black and yellow wire somewhere in the circuit?
Finally, how would I test whether the capsule itself is working or not? Would I want to speak into it and measure if it generates any current? If so, how would I do this with the multimeter?
Thanks in advance!
