A turntable that has a platter that can be vertically positioned so that the VTA between the stylus of the cartridge and the record can be easily adjusted without tweaking or touching the tone arm. The turntable includes a base, a platter, a spindle assembly configured to position the platter above the base, and a spindle adjustment mechanism configured to selectively position the vertical position of the platter with respect to the base. In one embodiment, the spindle adjustment mechanism includes a drive shaft that is configured to engage the spindle assembly and to selectively drive the spindle assembly up or down. As the spindle assembly is moved up and down, the platter moves up and down with respect to the base. In another embodiment, the spindle assembly includes a spindle shaft configured to rotate inside a chamber of the spindle assembly. A bolt which attached to the spindle shaft is configured to move up and down when the spindle shaft is rotated. The platter, which supported by a ball bearing resting on the bolt, moves up and down with the bolt as the spindle shaft is rotated. With either embodiment, a remote control unit or a mechanical crank can be used to move the platter up or down with respect to base to adjust the VTA without touching or tweaking the tone arm.

The turntable platter configuration of the present invention includes a groove on the platter edge about its periphery to allow for an improved ergonomic finger control for a DJ to alter the speed of the platter rotation. The turntable platter configuration also includes a regularly spaced shape about the periphery of the platter to be used with a strobe for allowing the user to ensure the rate of the rotation is at the appropriate speed, such as 33 RPM or 45 RPM.

A system including a phonograph record implement having a phonograph record with a plurality of grooves operable for recording audio data. A record player device is configured to read the audio data contents of said phonograph record implement. A wheel appliance moves or rotates on said phonograph record implement to produce an audio signal and a needle appliance reads or translates a plurality of grooves to an audio signal as the record player device moves around the stationary phonograph record. A speed control switch is operable for selecting at least one preset speed from a plurality of varying preset speeds for said record player device to operate. A wireless transmitter, which transmits the audio signal to an external receiver, which receives the audio signal produced from said stationary phonograph record for listening remotely.
