46 Chapter 3 Using Your iMac
Audio In/Optical Digital Audio In Port
You can connect external microphones or other audio equipment to the audio in/
optical digital audio in (,) port. The audio in port does not provide power to a
connected device, so you must use self-powered devices.
The audio in port is also a S/PDIF stereo 3.5 mini-phono jack. You can use a Toslink
cable and a Toslink jack-to-miniplug adapter to connect a Digital Audio Tape (DAT)
deck or digital instruments to input and mix your own music.
