Unlike dealing with some bigger companies, you'll find we always try that little bit harder to keep you happy - resulting perhaps in good word of mouth, a referral or a testimonial. When connecting the male into the female, the inner hot (signal) connection is made before the ground connection has been guaranteed; this often produces a loud buzz if the equipment is active when the connection is made.

The exact release date of this connector is still a little vague. The following dates were derived from historical RCA documentation. 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.

Retrieved 2011-08-23.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. [14] 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. [11] [15]

RCA Manufacturing Company. p.290. Disadvantages [ edit ] "Bullet plug" variation – Note the hollow center conductor and the pin point for the return signal. 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. By no later than 1937, RCA introduced this connector. 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. [9] [10] Originally, the concept was intended as an easy method to unhook sources while troubleshooting the console during servicing.
