Production Status: Discontinued / Vintage

The 55S (Small Unidyne) is a compact dynamic multi-impedance microphone with a cardioid polar pattern response. This features improvements in the redesigned Shure patented acoustic phase-shift network that has been redesigned and a revised moving-coil system now providing high efficiency and extended, smooth, frequency response. The large air-gap clearances, together with a rugged coil construction, provide immunity of the moving system to abnormal atmospheric conditions and severe mechanical shock. It is ideal for public address, theatre-stage sound system and remore broadcasting applications. Includes high-quality 14-foot cable (4.1 m). The 55s is smaller than the Model 55, and is therefore ideal for installations where it is desired to keep the microphone size to a minimum and still retain maximum operating efficiency. A new self-adjusting swivel permits tilting of the head through 80° so that the microphone can be aimed at the source of sound. The 55SW variant is equipped with an on/off switch.
