Forthcoming Buffer/Inverter question

[DadTheTinkerFairy]

No build documents available yet so I’m wondering if this will be capable of using the inverted and non-inverted outputs simultaneously for use as an active direct box. ?? Doesn’t seem like there are quite enough components on the board to do this the way I am familiar with.

That doesn’t look like a balanced line driver to me.

I'm still playing around with the design of this one, the simple ones seem to take me the most time to find a happy place.

Yes, you can use the in-phase and 180° shifted outputs simultaneously.

I still need to test it, but I also have a small XLR-jack mounted board that accomplishes a similar task.

Ooohh. The XLR mounted one sounds perfect. I have use the AMZFX multipurpose opamp board for this in the past but had to modify it to remove the gain he designed into it and added a voltage divider to the input because the output was still too hot.

The solder joints on those XLR jack pins though…
