The history of this mic technique is full of experimentation but sometimes too many variables is a bad thing. Having a fixed mixer should allow me more consistent results while still leaving some room for fine tuning by mic positioning.
"... we would pan the left and right tree half left and half right, and the outrigger mics we would pan hard left and right ..."
With this in mind, I have labelled (& positioned) the XLR inputs in the following order (when looking at the rear):
- L/1 at full signal strength into left channel. For L mic of 3 or Left outrigger mic of 5.
- L/2 at half signal strength into left channel. For L mic of 5 or not used.
- C/1 at full signal strength into both left & right channel.
- R/2 at half signal strength into right channel. For R mic of 5 or not used.
- R/1 at full signal strength into right channel. For R mic of 3 or Right outrigger mic of 5.
This naming convention is used for the XLR socket, the P48 jumper & the GND/float jumper of each input.
This makes sense whether using 3 or 5 channels but is also to make use of KiCAD's enforcement of having component IDs ending with a number.
