How Do I Hook My Mac to My Mixer Board?

With advances in sound-recording technology becoming increasingly affordable to consumers, more people are creating their own home-recording studios using their computers. Apple’s GarageBand and other Mac recording applications make it relatively easy for artists and music enthusiasts to create professional-quality recordings and discs without investing tens of thousands of dollars in equipment. Although digital mixers included with the software recording applications do a reasonably good job of mixing sound levels for a few channels, they still do not compare with sound levels achieved with stand-alone mixing boards. Fortunately, a couple of options allow you to connect your Mac to a mixer.

Connect your Mac to a mixer board and create a recording studio.

Line-Out to Mixer Connections

Step

Connect the mixer board to other instruments, microphones or sources you want to use in the recoding. Connect the power source to the mixer. Connect the amplifier and speakers to the mixer board as well.

Step

Connect the small end of the 3.5mm-to-RCA cable to the line-out jack on the back of the Mac computer or on the side if a MacBook. On many Macs, the line-out port has a green ring around it and might be the connection used for your computer speakers if you are using a desktop computer. Other Macs have a headphone or audio-wave symbol next to the port to differentiate it from line-in or microphone ports. Disconnect the speakers from your computer if the port is already in use.

Step

Connect the other end of the audio cable to the RCA line-in or auxiliary jacks on the mixer. If the mixer does not have RCA ports, use an RCA-to-1/4-inch adapter to connect the Mac to the mixer board.

Step

Open an audio or music player application on the Mac. Load an audio file into the player, then click “Play.” You should be able to hear the sound on the external speakers connected to the amplifier plugged into the mixer board.

Line-In From Mixer Board

Step

Shut down the Mac computer and the mixer board. Plug the 3.5mm-to-RCA audio cable into the line-in port on the Mac. In most cases, the line-in port should have a blue ring around it.

Step

Plug the other end of the audio cable into the RCA line-out jacks on the mixer board. If the mixer board does not have RCA output ports, connect the RCA plug to an RCA-to-1/4-inch adapter cable. Plug the 1/4-inch plugs into the right and left output jacks for the mixer.

Step

Power on the mixer board, then your Mac. After the Mac boots, open an audio-recording or audio-mixing application. Power on the source device connected to the mixer board.

Step

Click “Record,” “Import” or “Stream” in the audio application, then play the audio from the source device. You should be able to hear the music over your Mac speakers.

Step

Use the dials or sliders on the mixer board to adjust the levels of the source music. You can hear changes you make on the mixer board over the Mac speakers.
