I've recently seen the schematic for the Alctron MA-1. However, there are a couple of features that aren't clear and I hope to get some help from the group.
?
On the input side, after XLR1, there are two items labeled S1 and S2. They look like switches. S1 could be a mute switch. S2 looks like it connects XLR1-3 to either R1 or R2, perhaps to compensate for mic Zin.?
?
The other question I have is: where is power applied? Alctron's literature says it "operates on 48V, but does not pass phantom power to the mic." OK, but where is the power applied??
