Hi,
I wach this forum a couple of months and this is time for my first post.
I have AT853 brought at soundprofessionals and I run it with my minidisc sony MZ-R900. I use configuration with mic input. Microphone has electric power from mic input and work OK (no many hiss but has hiss). Now I decided to upgrade my configuration with MIY mic preamplifier with THAT 1510 or INA217 (I will use THAT beacouse they claims that circuit need about half electric power for work, about 7 mA). That schematics is for balanced microphone, so my question is : does AT853 have balanced output. If yes,can somebody teach me how to use wires for +- which balanced input request. If microphone has FET transistor inside, than output from D and from S are inverted?? I mean I can get balanced output. Any advice welcome. Sorry for my English, I am from Serbia.

The output of your mics are not balanced..
They are
Ground wire -copper color
Signal out Yellow - for three wire
Operating voltage for the FET RED- for three wire.
It would be more simple for you to convert your mics to two wire with my 4.7k mod ( do a search )
This mod is basically puts a resistor in between the Yellow wire and ground and then uses the red wire for output.
The "that" chip is great but I think your better off starting with something a little more simple like the ne5532 dual opamp use one side for your left the other side for your right. The rest of the circuit design is up to you. I would also check out the OPA2227PA. as a better choice over the ne5532.

Thanks a lot !
