TRS microphone wiring

[dirt]

Hi,

What is the recommended wiring when using a condenser microphone (such as the Rode Videomicro I, link) ? It has an TRS output, which should be the following from what I saw on the web:

Source	hobby-hour	speechrecsolutions	sound-au
Tip	Signal	-	+ Signal
Ring	+5V	+	+ 5V
Sleeve	ground	ground	ground

I want to use it with a Canon camera (EOS 1200D) that does not have an external microphone input, by adding a small switch-TRS input line (such as this one). Inside the camera, the internal mic is only connected with two wire (red and black) that I assume should be connected to the tip and sleeve (respectively) of the TRS connector. However, this image from this instructable only uses the tip and sleeve of the connector. How would that work ?

I intent to test some connections with another camera once I will receive the microphone but in the meantime I would really appreciate some insight on this subject.

No not that one that's stereo you only got one microphone so it's mono.
You have to make sure the internal microphone is an electret microphone

Yes and no it's very confusing.
This is also a TRS

You must confirm if the internal microphone is in fact a electret microphone and the voltage is compatible with your microphone
If it is then the support circuitry the components the 4.7 microfarad capacitor and a 2.2 kilo ohm resistor
Or value is very similar could be inside as well but you will have to Short the tip and the ring together on the female connector cuz it needs that 5 volts
In operation 5 vdc it's applied via the 2.2 kilo ohm resistor when you speak into the microphone (AC) alternating current passes through the 4.7 microfarad capacitor which also blocks the 5Vdc.
From the data sheet.
You must short pins two and five.
By the way that's why you only see
The tip and sleeve from the photo of instructables very instructive isn't it?


This is what you want to accomplish

Tip& ring or shorted.
Have a nice day...
