The sound input and output ports accept 3.5-mm connectors. There are two types:
m The stereo miniplug is found most often on stereo equipment; it works in both the sound
input and sound output ports.
m The extended miniplug, which is slightly longer and is found on voice-quality
microphones (such as the Apple PlainTalk Microphone), works only in the computer’s
sound input port (≈). (Even though it will fit into the sound output port, it won’t work there.)
If your equipment has a different connector from those shown here, you can purchase an
adapter at an electronics supply store.
The optional left and right RCA-type audio ports
Some models of this Macintosh also have ports that accept left and right input and output
through RCA-type connectors. These connectors are found on devices like videocassette
recorders (VCRs) and tape decks. The RCA-type ports are color-coded: red for right, and
white for left. (The yellow ports are for connecting video equipment.)
