Hi,
This question revolves around creating a simple microphone that I can connect to my digital recorder.
I bought an electret microphone and a 3.5MM mini phono plug.
The max impedance for the Electret is 5uF and Max 10V.
I know the electret has 2 imputs, voltage & ground.
When I connect the electret to the plug, do I need to place the appropriate resistor to stay within the 5uF maximum (2.2Kohm)? Or will it be automatically regulated by the digital recorder?
Also, in many schematic I've seen on the Web, they include a capacitor in the connection of the mic and the audio output. Do I also need to use a capacitor in my connection?
My digital recorder is an Olympus DS-330.
In order to make my external microphone work, do I need these 4 parts?
1) 3.5MM Mini Phono Plub
2) Electret Microphone 300 - 6Khz
3) 2.2Kohm resitor (to meet .5uF at max 10V)
4) Electrolytic?
or do I simply need the 3.5MM mini plug, the electret Mic and the 2.2kohm resistor?
I'll try to get pictures of the 3.5MM mini plub, but for now, these are my questions.
Note: I was under the impression that creating an external microphone was simply connecting the wires together with a resistor(because I'm very new to electronics) and directly to the plug.
