Happy New Year!
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.
