GENERAL PURPOSE MICROPHONES

Unidirectional Line Microphone

MODEL 644 SOUND SPOT’ – Another Electro-Voice revolu-

tionary development, the Sound Spot Model 644 is a combination

cardioid and distributed front opening instrument, making it

the most directional P.A. microphone ever. The Model 644

has the farthest front pickup, or better than 2.5 times the working distance of pressure types. Work close or far away

without change of frequency response.

Cancellation from the rear and sides exceeds 20 db abose 700 cps

giving practically complete rejection of unwanted sound.

Cardioid below 700 cps. This feature gives extremely high

rejection of random noise. Reverberation and feedback are vastly

lower than with any other P.A. microphone, allowing much

greater leeway in loudspeaker placement.

The effective front acceptance angle is 45 each side of center,

providing best isolation of individual performers. The Model

644 is 9 dh better on the reduction of wind noise and has far

less response to shock than most other microphones.

Frequency response is smooth from 40 to 10,000 cps. Acoust-

alloy 1, diaphram. High output: -53 db. Dual high and low

impedance selected by changing one tap on MC4M cable con-

nector. The case is high-pressure die-cast zinc with 3/4″ aluminum

tube; satin chrome finish. Rear diameter 2518″, length 16″. Cable

is 16′. Net weight, 2 lbs. () oz. List Each

Projector Horns

Completely new designs assure finest performance with ElectroVoice projector horns. Two basic types ‘rom which to choose . . . compound and reentrant. EXCLUSIVE COMPOUND HORNS permit widest range at lowest distortion, plus complete directional control of both highs and lows. Best wide-angle coverage with exclusive diffraction horns means better sound through entire coverage area. Concentrating compound horn provides highest efficiency at lowest distortion. Natural voice and music reproduction result in higher intelligibility without annoying peaks.

MODEL FC100-Similar to the famous CDT”, the FC100

provides two diffraction horns for uniform wide-angle coverage.

Frequency response is not compromised since both horns are

ideally designed to handle a specific portion of the range. Com-

pound horn reduces distortion far below any other projector

design. Flexible coverage control provided by individual adjust-

ment of each horn. Large horn is fiberglass with Mesa Tar finish

molded in. Use any E -V convertible driver. Specifications: Low –

REENTRANT HORNS provide wide, range than ever before at lowest cost. Unique E -V ring reflector design provides better balanced highs than possible with conventional exponential designs, by reducing high -frequency losses otten encountered in reentrant horns. Smooth et response plus added useful range increases intelligibility and adds to more natural sound. Rugged aluminum die- cast mounting plate plus precision die-cast reentrant tubes assure long- lasting performance. Heavy spun aluminum round bell or fiberglass rectangular horn provides either concentrated coverage or medium angle coverage. Electro- Voice Reentrant Horns accept any standard driver with 13,8″-18 threads.

MODEL FR150 -Reentrant Horn. Medium -angle low-cost rectangular horn provides good coverage at low cost. Virtually indestructible fiberglass horn has Mesa Tan color molded in. Adjustable mounting angle allows best coverage. Can he stacked for multiple speaker applications.

Versatile Convertible Drivers

Now, fur the

here are driver-, that can be used interchange-

ably in compound or reentrant horns. Used on either type of horn, the

new Electro-Voice Convertible Drivers feature highest efficiency

available. Increased power handling plus extra increased efficiency

make the 40- and 50 -watt drivers uniquely useful where high power at

minimum cost is essential. The high efficiency of all E -V Convertible

Drivers is achieved without resorting to “peaked” response which

may increase loudness, but does reduce intelligibility. The smooth

response of these drivers insures most natural reproduction of voice

and music for more satisfying quality with vastly reduced feedback

problems and greatly increased tonal range. Double flux ceramic

magnets provide long-lasting high efficiency in entirely new low -loss

magnetic circuits. Edgewise -wound ribbon voice coils give 18% more

efficiency.

The drivers are rugged and weatherproof: conversion to either reentrant or compound use can he made instantly in the field. Voice coils are also field replaceable, thus reducing repair costs to a minimum. E -V Convertible Drivers are available with 16 -ohm voice coils or with built-in 70.7 -volt line constant voltage transformers. This entirely new design concept gives better performance at minimum cost, making E -V Drivers your best buy.

is a name which, for nearly forty years,
Zap’
has commanded world-wide respect in the manufacture of microphones, high fidelity components, loudspeakers and loudspeaker systems, phonograph needles and cartridges, electronic organs, and special military products.
All basic manufacturing processes – die-casting, plating, machining, stamping, plastic molding, and tool-making-are housed within our own plants -a fact which enables E -V production experts to establish and control quality standards from original concept to final product. The benefits of production economies thus achieved are passed on to ElectroVoice customers in the form of better products and lower prices.
Electro-Voice laboratories are manned by the industry’s largest staff of engineers devoted exclusively to audio -acoustic product development. Specially designed E -V test equipment is used for research and quality control and a never-ending search for new design techniques to meet the rapidly expanding needs of industrialists, technicians, and consumers.
Engineering milestones in E -V history are many. The microphones used by U. S. astronauts in nearly all of the successful Mercury orbit projects, and those which will be used in the Gemini space program, were designed and manufactured by Electro-Voice, and an Academy Award – the first accorded a microphone manufacturer in twenty-two years-was conferred on an Electro-Voice design by the Academy of Motion Picture Arts and Sciences for outstanding contribution to motion picture production, at the 1963 awards presentation.
Outstanding microphone design contributions include the Differential Principle of noise pick-up cancellation, the Mechanophase Principle of cardioid unidirectivity, the Acoustalloy Diaphragm, the Variable -D cardioid dynamic microphone principle, and an improved Distributed Front Opening principle which makes possible highly directional microphone
pick-up.
E -V developments within the loudspeaker field include an exclusive diffraction horn design, Radax coaxial loudspeakers, Sonophase throat design, separate two-, three-, and four-way high fidelity loudspeaker systems, Line Radiator loudspeakers, and Compound Diffraction Projectors for public address applications. Electro-Voice also developed the first monaural and compatible stereo -monaural cartridge and the Power Point an integral cartridge -needle transducer – which had widespread impact on the entire phonograph pickup industry. A recent contribution is the E -V Featheride cartridge design which offers complete protection from needle scratch.
It is to the successful combination of people, products, policies, and an affinity for craftsmanship and production techniques that the ElectroVoice name owes its universal popularity – and it is this same combination which is your assurance that your finest choice is – and will always be – Electro- Voice.
