The turntable, which received the status of the world's first “smart” vinyl player, looks more like a bulky mobile phone of not very actual design. It is equipped with a sensor that tracks tracks, an integrated cartridge and a needle, and can broadcast the recording to speakers or headphones via Bluetooth. The device works with 7-, 10- and 12-inch vinyl records and maintains a speed of 33⅓ and 45 revolutions per minute. You can control playback, speed, volume, etc. using a mobile application for iOS and Android.
An extremely rare device, in the history of the creation and release of which - in extremely limited editions - is more fiction than truth. The player was created in the early 1980s and created a real sensation. It uses a unique (never used) self-centering system, or the search for the absolute center of the plate. If the device "recognized" the problem, the player self-centered the vinyl disc, compensating for deviations.
A turntable with a laser beam instead of the usual needle, the prototype of which was first presented to the interested public in 1986 at CES. Among the stated advantages is the absence of noise that occurs when the needle contacts the surface of the disk.
The development did not go into mass production, but the patent was sold to the Japanese company BSR, which later turned into ELP Japan and issued the ELP-1XA player ten years later - already with two lasers for reading - and at a price ten times higher than the price of the prototype.Source : http://www.avreport.ru
