PICKUP PATTERN SYMMETRICAL ABOUT

AXIS AND UNIFORM AT ALL FREQUENCIES

The world's finest moderately priced dynamic cardiojd microphone for public-address system use. The

Unidyne Ill approaches the theoretical ideal of the cardioid pickup pattern. This means completely uniform

pickup about the axis at all frequencies- in all planes. Remarkably fai thf ul reprod uction of the human

voice makes the Unidyne Il l a superior choice fo r public-address applications. Low frequency character-

istics of the Unidyne I ll eliminate boominess, and make it a favorite for pickup of drums and bass

instruments. Striking black and satin chrome finish in compact modern design makes the Unidyne I l l a

stylish addition to any platform. Model 545 is suitable for handheld and/or stand use with Model A25

Swivel Adapter included. Model 5455 is mounted on lifetime swivel and includes on-off switch. Model

The Commando Series represents a significant achievement in providing quality performance at

nominal cost - ncorporating Shure's rugged, patented Controlled Magnetic cartridge in a dramatic-

looking versatile series of microphones. Suitable for indoor or outdoor use, these microphones feature

high output, smooth response, extreme ruggedness and ability to withstand severe moisture and tem-

peratur e conditions. Mod el 420 is specially designed for lavali er use and it , as well as the Mod el 430,

features adjustment for high or low impedance by simple pin-jack changing method. Model 430

includes an "On-Of f" switch as well as detachab le cable. Both Models 415 and 430 are furnished with

Shure Mode l A25 Swivel Stand Adap ter for Stand-mout;ted use. Mode l 425

i s

specially designed for

gooseneck mounting but can also

be utilize d as stand-mounted units with A25B Swivel Ada pter Model s

with gooseneck attached are numbered 425-6 plus number to indicate length of gooseneck in inches.
