what does this mean

[Electro-Ghost]

Since it has a FET transistor inside, it needs a 10k resistor to power it (2.2k is too low unless the battery is 3V) and the resistor is its load. Since its output level is very low and its impedance is high, shielded audio cable must be used to connect to it.

Wat?? Wat?? Wat?? Wat?? Wat?? Wat?? Wat?? Wat?? (one byte)

Don't you understand my English? Don't you understand my geek-talk?

 

[Electro-Ghost]

sorry what i meant was what is a sheilded whatever u said, and what were u talkin about the restistor bein its load

A 2-wire electret microphone has two pins. One is connected to its metal case and is the ground and the other is its output.

it came as a mic that was meant to plug into a 1/8 jack
here is a link to it https://www.radioshack.com/product/index.jsp?productId=2102927&cp=2032057.2032187.2032192&pg=3&parentPage=family

and wat does sheilded mean

 

[audioguru]

A shielded audio cable has an insulated signal wire down the center and many strands of wire around it which shield it from interference. The many strands of wire sometimes are braided and are connected to the circuit's ground. Some shielded cables use foil or metalized plastic film as the shield. If shielded cables are not used for low level microphones, then ordinary unshielded cable picks up mains hum as interference.

You can use your battery-powered microphone with the LM386 circuit if you remove the 2.2k or 10k resistor that would power and load an ordinary electret microphone.

so ur are sayin if i reconnect that switch that says on/off to the mic and put a batt in it and remov the resistor it'll work

 

[audioguru]

I think you should put your microphone together with its switch and battery. By itself, it might have 3-wires or it might have a resistor built-in. Then the amplifier circuit desn't need the 2.2k or 10k resistor to power it.

i looked inside and it just has 1 non insulated stranded wire wrapped around one insulated stranded wire that is wrapped around a thread like thing

 

[Hero999]

That'll do fine, connect the uninsulated wire to 0V and the insulated wire to the input.

however i opened up the on off switch and i saw a disc cap and a resistor in it that was brown red red gold is it still ok

 

[Hero999]

Yes, that's the resistor for powering the microphone and the disc capacitor is probably for DC blocking.
