Connecting Music Mixer into Macbook Pro
I have an Alto ZMX122fx mixer. We are two guitar players/singers and we have both our guitars and both our mics plugged into the mixer. We want to do a live stream but with the sound coming directly from the mixer and not from the room. We want to connect the mixer to the macbook pro. We are using OBS to run the stream and the audio. What we saw on Youtube is two 1/4 inch jacks going from the main out of the mixer, into a 3.5mm cable and then we plugged that into aa sound card adapter (mic input) which plugged directly into the usb-c input on the macbook. The sound coming in was so distorted and choppy. What did we do wrong? Do we need some kind of digital processor between the mixer and the laptop?
Here are the cables we are using from mixer to Macbook:
