EZ1290 Switch Wiring + Fet DI

[inf0]

Hey there! I'm currently working on a EZ1290 project and I wanted to get some help with the wiring for Phantom / Impedance + Phase(or PAD) as well as incorporating a FetDI circuit

I'm using DPDT push pull switches and I'm a bit confused as to how to properly combine everything and avoid having any possible issues

I'm aware of the jlm go between approach but even if I use that , it's gonna bother me that I haven't learned how to do it manually if it makes sense.

I've drawn a wiring diagram based on what I could understand! I also included an empty wiring diagram if it's easier for someone to help me!
As a beginner , it gets pretty confusing real fast!

Thank you!

The LED should not be connected in the way shown - it is fed only from XLR pin 3 and one 6K8 resistor, unbalancing the line.
Also when the left hand switch is operated (to mute the audio?) XLR pins 2 + 3 are shorted - so the LED will glow brighter, as it is now fed from both 6K8 resistors.
Can you clarify what the terminals 2 - 6 connect to? (A transformer perhaps?).

Hi,
your drawing is a bit confusing to me.

For the Phantom power you are complicating too much.
You just need a SPDT switch (single pole double throw)
Check the phantom connections here:






For the Impedance switch,
you should do it this way:

You need to do a new drawing and incorporate the implementation showed in the above photos.
But don't do a new drawing in the same way as you did the one you posted here, because that's highly confusing.

Draw it like a schematic and like we read a sentence,
so draw the signal flow from left to right.
Leave the FET DI circuit out for now, first get the switches right, and only after that you should think about the FET DI.
For now, no DI in the drawing.

The signal flow is: XLR to impedance switch, to input transformer
And 48V into the XLR going through a switch

I always mention this re. phantom resistors: they need to be 1/2 Watt R's.
