HELP: i need to connect Yamaha TF3 to OBS

[Paul Rosseland]

Hello, this is Paul. My object is to stream audio and video using obs.
Let me explain my trouble, I use a Yamaha tf3 to capture the audio coming from the stage, and then I send 2 cables xlr through a matrix output 1 and 2 to another audio interface Behringer UMC 202 HD, which is connected via USB to an iMac using OBS. So I guess I can get rid of the little interface and connect directly my Yamaha to OBS but seems OBS only receive the signal through channels 1-2 of any audio interface, so this is the problem: in my mixer Yamaha, I'm using a matrix with digital output on channels 33 and 34.

How can I solve this problem and make OBS capture the signal through channels 33 and 34???

Probably a bit late now, but there was a Firmware update few years ago by Yamaha that address this to make it easier.
