AND GENERAL PURPOSE APPLICATIONS
Here are the finest of all the slender microphones yet
produced. They combine the best features of conventional
- velocity microphones with an advanced acoustical design.
MODEL Here, indeed, are high-fidelity microphones which deserve MODEL

superlative descriptions because of their outstanding per-
(Broadcust) formance and remarkable ruggedness. (General Purpose)
The "300 Series are multi-impedance velocity microphones of such a high order that they belong
in a class by themselves! They provide a Bi-Directional pickup pattern-permitting greater per-
former freedom (Performers can stand at a 73% greater distance from the microphone!). The "300
and 315 will pick up voice and music from front and back-yet discriminate against unwanted '
noises from the sides. They reduce reverberation and pickup of distracting random noises by 66%!
The Model 300 Broadcast is outstanding in performance-with a smooth peak-free response
from 40 to 15,000 c.p.s. It is appealing in design and its Special Grayie finish makes it ideal for
TV and all other applications where the microphone should blend into the background-and give
the spotlight to the performer. The 300 is a natural for television because it practically elim-
inates the pickup of moving props, scufiling feet, moving dollies, etc. The "300 is also highly
recommended for radio broadcasting, professional recording and remote pickup. It has a readily
accessible Voice-Music switch for perfect reproduction of the announcer or soloist working at close
range or for the distant instruments of the orchestra. The special vibration isolation unit (mounted in
live rubber) practically eliminates handling noises and the pickup of floor vibrations. Has 20 ft.
3-conductor, shielded broadcast-quality cable-with Cannon XL connector.
Model 315" General Purpose is similar in size, design and technical features to the Model 300
-with a smooth, peak-free response from 50 to 12,000 c.p.s. It is finished in a rich, soft satin
chrome-ideal for those numerous public address applications where its streamlined design and
striking beauty lend dignity and prestige to any setting in which it is used. Its Bi-Directional pickup
pattern is effective over a broad frequency range --and it permits the sound system to be Operated
at a level almost 6 db higher than is possible with non-directional (omni-directional) microphones!
The 315 has an acoustically streamlined external grille which filters out the boom and blasts often
heard over conventional microphones. It is a dependable unit which will provide highly satisfactory
performance even under adverse operating conditions. Has 20 ft. 2-conductor shielded cable and
plug assembly.

MULTl-IMPEDANCE DYNAMIC MICROPHONES
NEW SMALL UNIDYNES
The Small Unidynes are the only small sized uni-directional mov-
ing coil dynamic microphones. They are completely new micro-
phones with improved performance, yet retaining all of the highly
desirable features of the world famous original Unidynes. The
internal unit, based on the Shure-patented Uniphase principle,
has been designed for high overall efficiency and extended peak-
free frequency response. Rugged coil construction also provides
greater immunity of the moving coil system to abnormal atmo-
spheric conditions and mechanical shock.
Model 555 and Model 5565 are considerably smaller than the
original Model 55 and Model 556 and are ideal for installa-
tions where it is desirable to keep the microphone size to a mini- (F::::ta"':::;fl
mum and still retain operating efficiency.
The Small Unidynes are Perfect Performers-ideal for high quality public address, theatre-
stage sound systems, recording and remote broadcasting. Because of the unusual ruggedness
and reliability, Model 555 is also recommended for fixed station use in the Police, Fire and Trans-
portation services. For studio broadcasting and television use and similar applications where the
utmost in qualty is desired, Model 5565 is rec0mmended. Small Unidynes reduce reflection
and reverberation, decrease random noise energy pickup by approximately 67%, allow per-
former to stand at a distance from the microphone 75% greater than is possible with non-direc-
tional (omnidirectional) microphones, have smooth response from 40-i5,000 c.p.s at front-dead
at rear. Standard 5/3"--27 thread. Both are supplied with a 20 foot, high-quality cable and plug
assembly. Model "556$" features a Cannon XL type connector, and it also has a special newly
designed shock isolation unit of live rubber construction.
Dimensions for both units: case 3%," high: 2%" wide. 31/16" deep.
Shipping Weight: "55$ 3% pounds,- "5565" 3V2 pounds.
