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-
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 recommended. Small Unidynes reduce reflection
and reverberation, decrease random noise energy pickup by approximately 67'4', allow per-
former to stand at a distance from the microphone 75} greater than is possible with nonodirec-
tional (omnidirectional) microphones, have smooth response from 4045.000 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 5565" features a Cannon 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. 3%." deep.
Shipping weight: "555" 3% pounds; "5565" 4% pounds.
