The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a household device for the reproduction of sound from a phonograph record. A phonograph differs in principle from a gramophone; it converts the mechanical vibrations of the needle in the sound pickup to electrical oscillations, which are then amplified by an audio-frequency amplifier and converted to sound by an electroacoustic system, which includes one or more electrodynamic loudspeakers.

Phonographs are designed to reproduce monophonic, stereophonic, or quadraphonic disk recordings. The sound quality and the convenience of use depend on the phonograph’s rating. For example, phonographs manufactured in the USSR according to the All-Union State Standard, which establishes the basic technical specifications (for example, range of frequencies reproduced and nonlinear distortion factor), are rated as superior, first class, second class, or third class. Modern superior-rated phonographs produce sound of such quality that the listener is completely unaware of noise and the various distortions that occur in the course of reproduction of disk recordings; such phonographs are the most convenient to use.

Balance the arm and apply a 1g tracking force by adjusting the tonearm weight.
* Balance the tonearm and set the tracking force at 1.5g.
* Before adjusting the cartridge, please follow the procedure recommended by the turntable or tonearm manufacturer.
The heaviest of the three was the Clearaudio, which also has a slightly higher tracking force and a slightly lower resonant frequency with my tonearm, but none of these differences had negative consequences with my system.
Manufactures of turntables, tonearms, and cartridges are making exceptional products these days.
Turntables from Rega, Music Hall, and Sumiko have excellent reputations, and all come with integrated tonearms.
Admittedly, the Triplaner tonearm I use is exorbitantly priced.
Believe it or not, the cartridge is the least important part of an analog set-up, the first being the turntable itself, followed by the tonearm. If you put a $1,000 cartridge on a 1972 BSR changer, it might sound better, but it would still sound like a BSR.
Non-new-technology items fall under the following categories: Power amplifiers, pre amplifiers, tuners, turntables, tonearms, and phono cartridges.
