The turntable bridge (the part of the turntable that included the tracks and that swivelled to turn the equipment) could span from 6 to 120 feet (1.8 to 36.6 m), depending on the railway's needs. Larger turntables were installed in maintenance facilities for longer locomotives, while short line and narrow gauge railways typically used smaller ...
Turntablism has origins in the invention of direct-drive turntables.Early belt-drive turntables were unsuitable for turntablism, since they had a slow start-up time, and they were prone to wear-and-tear and breakage, [9] as the belt would break from backspinning or scratching. [10]
Some turntables that were built in earlier days rapidly became unsuitable for the longer locomotives introduced. For example, the Roundhouse in London was built in 1846 to turn around steam locomotives on the line to Birmingham, but newer locomotives were too long within ten years—the building has been preserved and used for other purposes ...
Two turntables and a microphone" is the basic concept of a DJ's equipment. This phrase describes turntables (phonographs) and a microphone connected to a mixer. The DJ uses the mixer's crossfader to fade between two songs playing on the turntables. Fading often includes beatmatching.
It supplied turntables and autochangers to many of the world’s record player manufacturers, eventually gaining 87% of the market. The company also manufactured their own brand of player, the Monarch automatic record changer, which could select and play 7", 10" and 12" records at 16, 33 1 ⁄ 3 , 45 or 78 rpm, automatically intermixing ...
[17]: 75 The turntable also provided "cinematic" changes of perspective on a scene, and, crucially, permitted the cast to walk against the revolve for dramatic motion. [17]: 98 Double-rotating stages, known as a concentric revolve, have also been used in theater productions such as Hamilton. Having one revolving stage inside of the other allows ...
In a direct-drive turntable the motor is located directly under the center of the platter and is connected to the platter directly. It is a significant advancement over older belt-drive turntables for turntablism, since they have a slower start-up time and torque, and are prone to wear-and-tear and breakage, [5] as the belt would break from backspinning or scratching.

The playing time of a phonograph record is directly proportional to the available groove length divided by the turntable speed. Total groove length in turn depends on how closely the grooves are spaced, in addition to the record diameter. At the beginning of the 20th century, the early discs played for two minutes, the same as cylinder records ...
