Matrix clarification/issue on SD9

[Van Cook]

I recently purchased an SD9 for our church. I have a Matrix question that seems odd to me regrading our organ matrix and how it is working...

I have my Group Master L & R feeding mtx IN 1 & 2 so I can combined the L/R signals out to my mono sub channel using Mtx 8 out and other outputs. I then have our Organ's L/R channels feeding mtx IN 5 & 6 that I needed to combine into a mono signal using Mtx 4 Out that I send out over Madi and Avioms. My issue is when I raise, lower or mute my group "Master fader" on the board, it is also changing the output levels my organ matrix 3 output. I thought matrix output levels were only tied to the input channel levels selected for a given matrix out, and would not be effected by any master fader movement on the board. I have nothing ganged and my patches look correct. I know I can use an AUX to do this but now I am curious why my Matrix 4 out level would be effected by the master fader movements? Any thoughts on what I am doing wrong, or is this the way Digico does their matrix?

Thanks,
Van

Hi Van,
Matrix Masters should not follow the Master Group fader typically.

Are you okay with sharing your session file? I would be happy to take a peak.

I ended up just adding an AUX and combining the Stereo Organ to mono through the Aux for the Aviom send I needed. I just deleted the matrix signal flow. But thanks for asking. It was that are sum them from the Stereo buss to a mono bus.
