Audio Cables: XLR Connectors

Today’s Eio post is on audio cables, specifically Pro-Audio Cables (XLR, TRS, RCA).

XLR Connector

One of the primary electrical connectors used in professional audio, video, and stage lighting equipment is the XLR connector. They are used for lighting control, low-voltage power supplies, and other applications, and are associated with balanced audio interconnection.

For its design, they are circular and have between 3 and 7 pins. They are available in four main styles, including male and female versions in both cable and chassis mounting designs. According to Wikipedia, “the female XLR connectors are designed to first connect pin 1 (the earth pin), before the other pins make contact, when a male XLR connector is inserted. With the ground connection established before the signal lines are connected, the insertion (and removal) of XLR connectors in live equipment is possible without picking up external signals (as it usually happens with, for example, RCA connectors).”

Eio’s catalog carries an array of XLR connector cables. Some are dual XLR to XLR cables that come in male or female, or with different amounts of pins.

Cables To Go 40057 1.5ft Pro-Audio XLR Male to XLR Female Cable

Use this XLR to XLR cable to connect unbalanced sources to balanced XLR inputs. This pro-audio cable is made from 22 AWG twisted pair audio cable under an aluminum foil shield and 60% copper braid for maximum shielding from noise. The highly flexible 7mm PVC jacket reduces the risk of the cable kinking and damaging the conductors.

Bright nickel plating on solid brass connectors resists wear from reconfiguring and moving equipment from one venue to another. Spring strain relief on the 1/4in plug and a chuck strain relief inside the XLR reduce the effects of age on the solder joints and contacts.

Other XLR cables connect to TRS cables, mainly in 1/4 inch size. We will discuss TRS cables in a future post.

Use this XLR to 1/4in cable to connect microphones and balanced sources to unbalanced inputs. This pro-audio cable is made from 22 AWG twisted pair audio cable under an aluminum foil shield and 60% copper braid for maximum shielding from noise.

Finally, our other XLR cables connect to RCA adapters. We will also discuss RCA  cables in a future post, so look for it soon.
