The rugged "333" is highly recommended for motion-picrure studios. TV studios, radio stations, professional recording, and all other uses where quality requirements are of the highest. The "333" is super-cardioid, uni-directional-reduces the pickup of random noise energy by 73%-prevents the pickup of moving props and scuming feet. The "333" Studio features the patented, world-famous Shure "Uniphase" acoustical network system-a field-proved standard of quality.

It is custom-built to provide high fidelity reproduction of voice and music. The microphone has complete versatility and reliability for indoor and outdoor use and may be used: (1) an a conventional floor or desk stand, (2) in the hand, and (3) with the lavalier cord and belt clip assembly. The use of high efficiency magnetic materials and specially designed magnetic circuits has made it possible to develop this small microphone and still achieve maximum owrating effi- ciency. The microphone is ruggedly built to withstand hard usage and is unaffected by temperature and humidity variations. V&.300 \.umo GRADIENT^ BI-DIRECTIONAL RIBBON MICROPHONE* This professional quality multi-impedance microphone is widely used for tape recording, broadcast and highest quality Public Address use. The "300" has a specially designed anti-"PFF" filter screen-which eliminates pickup of distracting breath noises. It provides sound pickup at the front and rear of the microphone, but greatly reduces pickup at the sides. One of the outstanding features of the "300" is the fact that the microphone can be placed at a 73y0greater distance from the performer than is possible with omni-directional microphones. It is ideal for highest-quality reproduction, especially wherever multi-person pickup is desired, yet background noise must be reduced. *Available in matched setsfor sicreo recording at no additional cost.
