• Model: Small Unidyne 55 SH Series II - Shure; Chicago, Evanston,

• Notes

• The Model 55SH Series II provides the Shure classic UNIDYNE II design coupled with modern acoustic components.  See original model 55 S. 

  The 55SH Series II has a cardioid (unidirectional) polar pickup pattern that minimizes sound pickup from the rear of the microphone. This allows the Model 55SH Series II to be used in close proximity to loudspeakers without creating feeback problems.

  The 55SH Series II has a low-impedance balanced output designed for connection to microphone inputs rated a 75 to 300 ohms. The microphone features a cartridge shock mount to reduce stand noise, an On/Off switch, and an attached, self-tensioning, 5/8¨-27 thread swivel mount.
