XLR connectors - used predominantly for professional audio and video equipment, often used in theatre for the lighting.

Ring: Right-hand channel for stereo signals, negative polarity for balanced mono signals, power supply for power-using mono signal sources Balanced audio is typically achieved by TRRRS connectors while unbalanced audio is achieved by TRS connectors. How to know the audio signal output International Library of Technology: ...Principles of Telephony... International Textbook Company, Scranton, PA. 1907. p. 36. tip ring sleeve 0-1922.

The 3.5mm and 2.5mm sizes are sometimes called 1⁄ 8in and 3⁄ 32in respectively in the United States, though those dimensions are only approximations. [24] All sizes are now readily available in two-conductor (unbalanced mono) and three-conductor ( balanced mono or unbalanced stereo) versions.

Balanced audio is achieved by having two signal wires, in which one carries positive polarity while the other carries negative polarity. Unbalanced audio on the other hand is wired as having one signal wire and one ground/return wire. Audio signals are mostly transmitted to your headphones through a mono-aural or a mono signal or a stereo or a stereophonic signal. Stereo signals use left and right or 2 audio channels whereas a mono requires a single audio channel. Read the comparison guide about Mono vs Stereo. In a TRS connector, there is a ring in the middle of the tip and the sleeve. The ring is a conductor that produces a balanced or an unbalanced stereo signal or mono signal. MIL-P-642/2, also known as PJ-051. (Similar to Western Electric WE-310, and thus not compatible with EIA RS-453) To achieve balanced mono, the sleeve acts as the return wire while the ring acts as the negative signal and the tip as the positive signal. To get unbalanced stereo signals, the sleeve serves as the ground/return wire while the ring acts as the right audio channel and the tip to act as the left audio channel.

This makes the stereo signal create the illusion that sound is coming from different directions because it utilizes two channels which simulates “natural” hearing. This effect is usually called surround effect. Balanced vs Unbalanced audio Lewallen, Dale (1993). This Old PC. Ziff-Davis Press. p.362. ISBN 978-1-56276-108-0 . Retrieved September 8, 2016. Remember that sound cards use the smaller 1/8-inch mini-phono plug... The two-conductor plug allows audio signal to be transmitted in mono. The sleeve serves as a ground and return path while the tip transmits the audio signal. PDAs and mobile phones [ edit ] All iPhone models from the first generation to the 6S and SE (first generation) use a four-conductor (TRRS) phone connector (center) for a wired headset.

(2003). 100 Years of Telephone Switching. Amsterdam, the Netherlands: IOS Press. p.51. ISBN 9784274906114. To achieve balanced audio, there must be 2 signal wires with one wire transmitting positive polarity and the other one having a negative polarity. In unbalanced audio, there is one ground wire and another signal wire. The TRRRS connector is used to achieve balanced audio while the TRS connector is used for unbalanced audio. Personal computer sound cards, such as Creative Labs' Sound Blaster line, use a 3.5mm phone connector as a mono microphone input, and deliver a 5V bias voltage on the ring to power the FET preamplifier built into electret microphones. Adjustments may be required to achieve compatibility between different manufacturers. [42] From what you learned, there are four types of audio signals that may be carried using phone connectors: unbalanced stereo, balanced stereo, unbalanced mono, and balanced mono.
