What is RCA Phono?
An RCA Phono (also known as an RCA connector or RCA jack) is a type of electrical connector commonly used to transmit audio and video signals between devices. The RCA connector typically consists of a central pin (the male component) surrounded by a metal ring (the female component) that provides the ground connection.
In audio applications, RCA Phono connectors are often used for stereo sound, where you’ll see two connectors: one for the left channel (usually white) and one for the right channel (usually red). They are also frequently used in home audio equipment like CD players, turntables, amplifiers, and televisions.
RCA connectors are typically used in analog audio/video systems, though digital versions like the RCA S/PDIF are also available. While modern systems often use more advanced connections like HDMI or optical cables, RCA remains popular due to its simplicity and widespread compatibility.
