What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Sansui FR-4060 turntable

Electronic Automatic Transcription Turntable

Stereo purists who still claim only a manually-operated turntable can faithfully reproduce disc recordings without strain have some catching up to do. For here is a turntable - a fully automated transcription turntable - which performs with the ease and stress-free operation of a first-class manual but has the convenience and practicality of an automatic as well. The Sansui FR-4060 very efficiently eliminates the one major disadvantage of the complicated :changer-type" turntable by employing a non-mechanical, purely electric device, the galvano-magnetic detection mechanism, to detect the end of a record and prepare the tonearm for automatic operation. It makes it possible for the tonearm to ride completely free of stress-producing mechanical linkage systems until it is time for the automatic lead-in, return, repeat or cut operations to take over. In this way, the stylus is protected from distortion-producing lateral thrust, your records are safeguarded just as they would be on a manual, and since the tonearm is free, it can be moved to any part of the record manually, even during automatic play.

 


 

The Frequency Response-4060 features an unusually sensitive S-shaped tonearm, a newly developed Sansui SV27 magnetic cartridge with superb tonal characteristics, a special low-capacitance output cable, floating-mount base and platter design and many other original Sansui quality details. It is also fitted with a connection socket for the Sansui SRC-6 control unit (optional) for full remote-control of all automatic functions.

Those stereo purists who maintain that a manual turntable is the epitome of perfection have only to check out the FR-4060. by adding the convenience of automatic operation to one of the finest precision manuals ever created. Sansui has come up with a turntable to fully satisfy your specific needs.
