Hi,
I thought I can ask the experts here

as i am still learning about this
the Mixer is connected via XLRs to mics (four) and portable speakers (six)
I am planning to use the M32R live with my laptop for a town hall and might need it for VC calls like Zoom. Can I use the USB from the mixer to send the audio in and out as I can see that the USB has 2x2 channels? in this case, the mics signal will go to the laptop as an input and the audio out from the laptop will go to the Speakers.
the other question is that I am using the 6 XLR output of the mixer to the Active speakers, so how can I group all those outputs in a single fader?
i have used the DCA to group all the inputs insto single fader ,but not sure how to group the outputs .
