...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!
Technical Data and General Information about the "Music Lovers" Cartridge
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:
5 to 8 grams for all types of records.
Without network-0.4 volts at 1000 c.p.s. With network-25 millivolts at 1000 c.p.s.
Recommended Load Impedance:
Input network (supplied with cartridge) is designed work into all magnetic preamplifiers with input impedance of 22,000 ohms to 1.0 megohm.
Approximately 14 grams-with network-which is equivalent to the most popular magnetic cartridges.
