Analog Audio Connectors and Signal Formats
Different audio connectors are suited for different purposes. Audio connectors are
often indicative of the kind of signal they transmit. However, there are enough
exceptions that it’s important to know what kind of audio signal you are connecting,
in addition to the connector type. An important distinction is whether an audio
connector carries a balanced or an unbalanced signal.
1/8" Mini Connectors
These are very small, unbalanced audio connectors. Many computers have 1/8" mini
inputs and outputs at –10 dBV line level, and many portable audio devices such as
CD players, iPod digital music players, and MP3 players use these connectors for
headphone outputs. Portable MiniDisc and DAT recorders often use 1/8" mini
connectors for connecting microphones.
Note: Some Macintosh computers and portable audio recorders also use a connector
that combines both a stereo miniplug and a 1/8" optical digital connection (see “
S/PDIF ”
on page 194) in a single jack.
RCA Connectors
Most consumer equipment uses RCA connectors, which are unbalanced connectors
that usually handle –10 dBV (consumer) line levels.
