Site maintenance in progress, some wonkiness may ensue. Thanks for your patience.
1) Simplest Question. The Green Pre circuit board has two outputs for Phantom Pwr at the end of the board, for powering the mic.
a) Can I simply add a resistor and capacitor in series with one leg of these outputs and take it to a SPST switch? (The board is supposed to just have a SPST switch right at that place).
b) Does it matter which leg of the output I put the RC on? Since the outputs on the Green pre are not labelled, I have just used "connector 1" and connector 2" in the diagram in the following post.
c) Can I just choose the values of R and C to get the time ramp I like? Example: T=RC. Take a 5 second ramp time and use R=5K, C = 1000uF.
d) If this will work fine, will I be inadvertently adding junk to the phantom power supply (distortion/noise) - I'm still not sure if phantom power, supplied to the mic, affects the audio directly (sorry, I'm really trying to understand this all but I'm slow at it).
) Do I need to use an electrolytic or film cap, or does it matter?
f) Is this just a totally stupid idea? I want to use my green pre with some great mics, but I'm a little concerned about sudden phantom power hitting them and damaging them. I thought using a slow rise phantom would protect them, and also eliminate some pop when they are turned on.
