Hi all, been trying to figure this out without posting but not having any luck so here I am asking.
Project - Have a video surveillance system, bosses now want it to have audio. Current system has inputs for audio so just need a mic and preamp to get to line in strength.
Using - M040 Preamp **broken link removed**
- Electret Mic **broken link removed**
- 10K Resistor
- Unknown value capacitor
- 15VDC Plug pack power supply.
Setup - With out the capacitor it just hums and nothing when I tap the mic, been told I need the capacitor but no idea what value.
So I guess the question is, Is this setup right? Will it do what I need? I don't need crystal clear audio, just good enough to hear any abuse from our clients.
Thanks and regards
Brendan
