Thanks Jeff-

I'm not using EUCON; just a DADmom configured through its software.

I see there is a newer version of the DADman software and MTRX firmware.

Here is the version I'm currently on:

MTRX. cpufw: 2.3.1.3, matrix 1.1.23.2, recovery 1.2.1.1
DADman ver. 5.4.2.1 (5.4.2 build 1)
Dante Controller ver. 4.2.3 (4.2.3.1)
Mac OS Catalina 10.15.7

I have a single FOLD DOWN to Mono.

I am not using a meter output back into Pro Tools with an AAX metering plug-in. I may be describing the signal flow incorrectly, but I do hear these volume drops when 2 Sources are engaged on the DADmom.

Looks like I should update everything first to see if the problem goes away...

Thanks--
