Shure 565SD, unidirectional dynamic microphone for vocals - predecessor model of the SM58 - known especially for its massive use at the Woodstock festival. The Shure 565SD features a solid metal grille, offers good rejection against wind and 'pops', has switchable Low-Z / Hi-Z impedance, and is equipped with an on/off switch. The 565SD is a popular choice for vocal applications on stage, in studios, amphitheatres, conventions, places of worship, and schools.
This microphone, in the first version, connected via a male Amphenol MC4M connector, with threads and 4 pins. It wasn't XLR. You had two cables, with the wires soldered in the connector according to the impedance you needed, and if necessary, you could change the cables. Now you are forced to open the microphone and solder the wires inside the microphone, which doesn't allow you to change during the concert.
