@!-Of RECTIONAL GRADIENT' MICROPHONE . . This rugged, high fidelity, multi-impedance microphone is widely used for television, radio broadcasting, professional recording and high-fidelity uses. The "300" reduces reverberation and the pickup o f random noise b y 66%. The "300" combines the best features of conventional velocity micrcphones with advanced acoustic design-including an anti-"PFF" filter screen. Its bi-directional polar pattern is effective over a broad frequency range. I t provides sound pickup a t the front and rear o f the microphone, but greatly reduces pickup a t the sides. One o f the outstanding features of the "300" is the fact that the microphone can be placed a t a 73% greater distance from the performer than is possible with omnidirectional microphones! The "300" has a non-reflecting "Baked Bronze" finish, so i t blends into the background, gives the spotlight to the performer. The "300" has a readily accessible Voice-Music switch, vibration-isolation unit mounted i n live rubber, and a multi-impedance switch, providing l o w medium and high impedance.

GENERAL PURPOSE MICROPHONES OMNI-DIRECTIONAL DYNAMIC MICROPHONES The new Slendyne 535 is the most versatile fine quality probe microphone ever developed - actually five microphones i n one because o f its practical design and useful accessories! The "535" is a movingcoil dynamic microphone built to provide wide range reproduction o f music and voice. I t can be used for indoor or outdoor applications i n the following manner: (1) in the hand, (2) on a floor stand, (3) o n a desk stand, (4) hung around the neck on a lavalier cord. Add to these factors a n on-off switch adapter and a dual-impedance switch and you have the most completely versatile fine quality probe ever developed. Frequency response is 60 to 13,500 c.p.s.. The Slendyne 535 i s ideal for high quality public address, theater-stage sound systems, and a l l recording applications where an amni-directional microphone is desired. The microphone is ruggedly built to withstand hard usage, and is unaffected b y temperature and humidity variations. The 20-foot, high quality, shielded, two-conductor cable is supplied with a microphone plug equivalent to the Amphenol 91-MC3M plug. The "535" meets the requirements f o r moximum quality and minimum size. I t is finished i n rich satin chrome. A self-adjusting swivel adapter is supplied w i t h the microphone, and permits i t to be tilted f r o m 90' from vertical to horizontal, making i t possible to tilt the microphone a t the source o f sound.

...A N e w Experience in Listening Pleasurel Here is an important development in the history of high fidelity reproduction-a three-speed ceramic cartridge which is specially designed to enhance the quality of all the popular high fidelity equipment in use today. It brings a new dimension to tone quality.. reproduces all instruments shorply and clearly. yet there is a subtle softness that records the original voice and music with a naturalness that will surprise and delight the most critical listeners. The "Music Lovers" Cartridge provides freedom from the induced hum and the magnetic "drag" prevalent with conventional high fidelity cartridges.

..

.

The "Music Lovers" Cartridge is equipped for mechanical interchangeability with magnetic pickups, and for direct connection to magnetic inputs of amplifiers not yet provided with constant displacement inputs, thus allowing the full advantages of compensation circuits.

A special feature of the "Music Lovers" Cartridge is the "twin-lever" needle shift transport--a unique device that provides lower mass and individual needle compliance for superior response-eliminotes needle interaction. The "Music Lovers" needle can be replaced quickly without tools in a matter of seconds-while tone arm-even blindfolded-with no danger of transposing the 3-mil and 1-mil tips.

it is in the

Investigate the "Music Lovers" Cartridge, for here is a high-fidelity cartridge which is in a class by itself. Being free of cartridge induced hum and magnetic "drag" i t provides a pureness of tone that gives you concert hall realism in the home!

Response Frequency Characteristics: A smooth response from 30 to 15,000 c.p.s. with a gradual "roll off" between 10,000 and 15,000 c.p.s. designed to ideally meet the exacting requirements of typical high fidelity reproduction. Equipped with network for connection to magnetic amplifier inputs.

A high lateral compliance of 1.5 x 10-%rn/dyne helps reduce record wear and allows the pickup to track and reproduce the full low frequency range at all speeds. Tracking Force:
