There are close to a dozen microphone connectors that you can buy right now. However, most of these are not that common. • Mini XLR has three types of mini XLR connectors: TQG, TA3, and TA4. These are smaller than the typical XLR connectors. • Tip-sleeve or TS connectors: can carry unbalanced sound signals and come in different sizes, including 1/4- and 1/8-inch sizes. • Tip-ring-sleeve or TRS connectors are used to transmit balanced sound signals in some microphones. The tip handles the positive polarity while the ring takes care of the negative polarity of the audio signal. • TRRS connectors are used when you have a microphone and headphones using the same connector. If the TS connector has one black band and the TRS has two, the TRRS has three. The tip, two rings, and the sleeve can carry the left and right audio signals, the ground, and the microphone signals. • TA5 connector is most commonly seen in wireless microphones and lavalier types. Other connectors such as the tube power supply, Nexus, Amphenol Tuchel, and Switch Craft 2501F are mostly outdated.
