Product Information

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.

Continuous noise can occur if the plug partially falls out of the jack, breaking the ground connection but not the signal. The hot signal wire and signal ground provided by an RCA connection implement an unbalanced connection. Devices mount the socket ( female jack), consisting of a central hole with a ring of metal around it.In the 1950s, RCA connectors began to replace the older quarter-inch ( 1⁄ 4inch) phone connectors for many other applications in the consumer audio world when component high-fidelity systems started becoming popular during the transistor revolution. For a time the 5-pin DIN connector was popular for bi-directional stereo connection between A/V equipment, but it has been entirely displaced on modern consumer devices.

The connector was labeled on the back of radio with one of the following terms: " Victrola", " Phono", "Pick-up", "Television". 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.The signal-carrying pin protrudes from the plug, and often comes into contact with the socket before the grounded rings meet, resulting in loud hum or buzz if the audio components do not share a common ground and are powered while making connections. 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. Its use as a connector for composite video signals is extremely common but provides poor impedance matching. While these are the standard colors found on commercially made products, cables with different-colored connectors may be used, as long as the cable itself is compatible with the application (for example, cables with 75 ohms impedance for video and S/PDIF).
