HELP - Mic Mute Pedal - Phantom Power and LED

[Hubbub]

Except that back to back 470u caps will give you total 235u.
You need to double the value when in series (back to back) so you'd need 2 x 2000u caps (or equivalent network) "back to back".

Sorry, I perhaps should have said in anti-parallel, or inverse parallel, where two 470uF parts would give 940uF. In my defense I did originally say parallel, which does give a sum result as I stated. Here are some other sites referring to polarized anti-paralleled parts as wired back-to-back:

HI
I just tried the schematic above and it works perfectly! No pop at all.. Thanks so much
for the led I use Standard leds and because of that it is DIM.

Two questions
1. I noted that using a dynamic MIC, the 48 volts current is dedicated to the LED so it lights up but
it is dim since its not a 2ma LED.

2. I also noted that when I use a Condensor Mic that uses the 48 volts the Led is totally off
as all the current is taken by the Condensor mic.

How can the circuit be improved? Obviously with the dynamic mic, I could lower the
resistor values to 8 K maybe for more brightness

But maybe not with a condensor mic as it could compete with the condensor mic?

I am not electronics trained so can someone suggest a solution?




Thanks
Allan

Hi
This is part of a circuit from http://www.uneeda-audio.com/absw/ .
It uses only 4.7k.. What do you all think of it?
