Shure commemorates the 75th anniversary of the legendary 55 Unidyne

Coinciding with this anniversary, Shure launches a limited edition microphone and promotes a contest on social networks.

The first microphone Shure 55 Unidyne appeared in 1939 in the United States and, since its launch, was adopted internationally as the essential microphone for broadcasts, speeches, recordings and two-way radio communications.

In the 1950s, the 55 Unidyne began to be frequently seen in musical performances, which rapidly increased in number, until it forged the image that has made it a cultural icon.

This legendary microphone turned 75 years old in 2014. A year that, in addition, Shure started on an excellent foot, since on January 31 the Institute of Electrical and Electronics Engineers awarded this microphone its 137th award.

To commemorate these milestones, Shure announced in late 2014 the release of a limited edition Unidyne model, the 5575LE cardioid dynamic microphone.

This new model is as iconic as the original and includes a number of features selected by Shure to improve its durability and sound quality.

The Shure 5575LE features the Unidyne III cardioid element, a larger outer grille, beautiful Vintage screen printing, and a zinc-plated finish. In addition, it is supplied with a silver table stand, in a small aluminum flight-case with the 75th anniversary logo.

Shure has only manufactured 5,575 units of this collector's gem that includes a certificate of authenticity.

Social media contest

To make the 75th anniversary celebration even more special, Shure has launched a social media contest. All those who have fallen in love with the 5575LE and want to get one can participate.

To do this, you will only have to send your 75th birthday wishes for the 55th Unidyne, through Facebook, Twitter or Instagram, adding the hashtag #5575th. All approved congratulators will be entered into a drawing in early February for the chance to win one of ten 5575LE microphones or one of two tours that will take the winners to visit Shure's headquarters in Chicago in spring 2015.
