All About RCA Audio Adapters and Converters

RCA audio adapters and converters are available for a range of applications. Originally a proprietary design for record players, this type of connection became the industry standard for carrying audio and visual signals. These devices are often used to connect audio equipment or audiovisual equipment like televisions.

What types of audio adapters and converters are available?

These RCA adapters and converters are used for several types of audio and visual feeds. They include:

  • Patch cords: This is a common type of cord used as a connector. Instrument audio cable is also a common configuration. These cords are designed to carry an audio or visual signal from one device to another. They're commonly used between DVD players and TVs. They’re also used to plug guitars into amps.
  • Digital-to-analog converter: This converter transfers a signal from a Toslink digital optical cable into something that can be transmitted through a standard RCA cable. These units typically have an indicator light for power, a left and right RCA output, a Toslink input, a DC5V input, and a coaxial input.
  • B&O turntable to RCA: This adapter accommodates a 7- or 5-pin connector from a Bang & Olufsen turntable. This adapter makes it possible to plug into a stereo's standard phono jack connection.
  • Splitter adapter: This type of adapter splits one feed into two feeds. A common configuration is one 3.5mm headphone jack to two RCA splitter adapters.
  • RCA to HDMI: This converter makes it possible to use a laptop with a television.
  • RCA female-to-female: This coupler features two female ports. It allows you to connect more than one audio RCA cable to another.
What materials are used in these converters and adapters?
  • Metals: A number of conductive metals are used in the connector portions of these adapters and connectors. Nickel, copper, silver, and gold are among the most commonly used metals in connectors. Of these, silver is the most effective conductor. Some high-end models are gold-plated.
  • Cable: These adapters most often use coaxial cable. Coaxial cables have a four-part structure, with wires arranged around a common axis.
  • Connector Type: Connector types include RCA male, perhaps the most common type seen in these devices. Others include 3.5mm headphone jack and VGA configurations.
What does the acronym RCA refer to?

Originally, this type of connector was developed by the Radio Corporation of America. However, it soon became an industry standard. For decades, this type of adapter has been available from a variety of manufacturers.
