Connecting Speakers and Other Audio Devices

Your MacBook comes with three built-in speakers, a built-in microphone, an audio line in/optical digital audio in port, and a headphone/optical digital audio out (f ) port.

You can connect external speakers, headphones, and other sound output devices to the headphone (f ) port. The headphone port is also an S/PDIF stereo 3.5 mini-phono jack. When devices are plugged in, sound won’t come through your built-in speakers. Unplug any headphones or speakers to hear the computer speakers.

You can record sound onto your hard disk using the built-in microphone located next to the built-in iSight camera. You can also connect external microphones or other audio equipment to the audio line in port. The audio line in port is also an S/PDIF stereo 3.5 mini-phono jack, which doesn’t provide power to a connected device, so you must use self-powered peripherals. Using a Toslink jack-to-miniplug adapter, you can use a Toslink cable to connect Digital Audio Tape (DAT) decks or digital instruments to input and mix your own music.
