The RCA connector mentioned in the text - (or RCA Phono connector or Phono
connector) is a type of electrical connector commonly used to carry audio and video
signals. The name RCA derives from the company Radio Corporation of America, which
introduced the design in the 1930s.
(The word phono in phono connector is an abbreviation of the word phonograph, because
this connector was originally created to allow the connection of a phonograph turntable to
a radio receiver. RCA jacks are often used in phono inputs, a set of input jacks usually
located on the rear panel of a preamp, mixer or amplifier, especially on early radio sets, to
which a phonograph or turntable is attached.)
