m& "332 STUDIO UNITRON UNI-DIRECTIONAL RIBBON MICROPHONE
This quality microphone is designed for discriminating users with the most exacting professional requirements. The rugged "333" is recommended for motion-picture 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 nolse energy by 73yo-prevents the pickup of moving props and scuffling feet. The "333" Studio features the patented, world-famous Shure "Uniphase" acoustical network system-a field-proved standard of quality.
"525 sTuDlo SLENDYNE OMNI-DIRECTIONAL DYNAMIC MICROPHONE
The Studio "525" is an exceptionally fine, slender microphone of broadcast 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) on 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 operating effi- ciency. The microphone is ruggedly built to withstand hard usage and is unaffected by temperature and humidity variations.
1/YlMu ''300''sTuDlo GRADIENT' 61-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 73% greater distance from the performer than is possible with omni-directional microphones. It is ideal fol highest-quality reproduction, especially wherever multi-person pickup is desired, yet background noise must be reduced.
