717A

Common name: Shure 717A

Production Status: Discontinued / Vintage

The 717A and the later model 717 B is a low cost pressure-actuated diaphragm-type semi-directional crystal microphone with wide range response for high quality reproduction of sound. It features a Tenite plastic case and handle. The crystal used is a Grafoil (high capacity) bimorph unit, moisture-sealed to withstand adverse climatic conditions. The microphone is provided with a 7-foot shielded rubber-jacketed cable. The Model 717A is designed for announcing, home recording and all general purpose use. The frequency response is suitable for either voice or music, and is free from undesirable peaks. The cartridge unit is mounted in rubber to provide mechanical isolation from the case, so that the microphone may be handled or carried about without annoying mechanical noise pickup.
