I want to direct my L/R mix to both OUTPUTS 15 and 16 but also to OUTPUT 1 … but be able to use the fader on output 1 to increase/decrease volume without impact the volume of the 15/16. The two use cases I’m trying to accomplish: #1: Use the Master Fader to do Front of House. Input faders 1-16 automatically route to stereo outputs 15 and 16. Then use the MIX 1 fader to take the FOH mix and lower or raise the volume to a different room/space. It’s OK if this MIX1 output is MONO. #2: I mix my band from stage. I want to put Front of House into my In Ears. I can do this by using the headphone jack into a blue tooth transmitter/receiver and get “stereo” in the in ears. But when I get signal via OUTPUT#1 XLR I only get one of the IEM earbuds to produce audio. I I would like to get audio to sound out of both earbuds. MONO into both sides of the IEMS would be fine. ---

Presuming you aren’t using an AHM and are in the wrong category… You don’t mention what console you are using, but what you can do is just use a regular mono auxiliary. Set it to be Post Fade for all channels, and send all channels to it at 0dB. Then just use the Auxiliary Master to control your level. ---

A “Matrix” buss is usually what you would use there. A matrix is a “mix of outputs/busses” (vs an aux which is a “mix of inputs”). You should be able to create a matrix and send the Main L/R buss to it “pre-fader”. The matrix will have its own volume fader. When you send the Main L/R buss to the matrix pre-fader, it ensures that any changes to the Main LR fader will not affect the volume level of the matrix.
