Your sound mixer should come with cables that plug directly into a port in your Mac computer.
Connecting your sound mixer to a Mac is a simple process. Once you have connected your mixer to other instruments or microphones, you then can connect the mixer to your Mac. Connect the smaller end of the 3.4 mm-to-RCA cable with the line out jack that’s in the back of the Mac computer or if it’s a Macbook, on the side of the computer. Then connect the other end of the cable to the RCA line-in or jacks on the mixer. You may need an adapter to connect the mixer to the computer if you do not have these things. You then should be able to play an audio file and hear the sound from the amplifier when it’s plugged into the mixer.
