About this deal
The hot signal wire and signal ground provided by an RCA connection implement an unbalanced connection. A true balanced connection is generally preferred in certain applications, particularly professional settings because it allows for the use of long cables while reducing susceptibility to external noise.

In 1937, it was used inside a RCA model U-109 radio- phonograph and model R-97 phonograph. In the U-109, the internal amplifier chassis had female connectors which accepted male cables from the internal radio chassis and built-in phonograph player.   Originally, the concept was intended as an easy method to unhook sources while troubleshooting the console during servicing. [ citation needed] In 1939, RCA introduced two radio- television floor consoles (TRK-9, TRK-12) which used the same internal connection concept but the audio output of the television chassis was connected to the radio/amplifier chassis via a male to male cable.  Three lower-cost 1939 television models had an audio output connector on their rear panel instead of an integrated amplifier and speaker: RCA TT-5, Westinghouse WRT-700, GE HM-171.   The male plug has a center pin that is 3.175mm (1/8inch) in diameter, and is surrounded by an outer shell that is 8.25mm (1/3inch) in diameter.
