The player has an updated motor that rotates the support disc according to the direct drive principle. The engine has a dual electromagnetic system, due to which it was possible to radically increase the smoothness of the ride and almost completely eliminate any vibrations.
The Technics SP-10RE-S reference-grade vinyl turntable system features a direct drive motor without a core and a heavy plate for stable rotation. It is equipped with a separate control unit to suppress the impact of unwanted noise on the main unit. These meticulous noise reduction measures ensure the highest S/N levels in the world.
The motor is equipped with a double rotor, which significantly reduces the load on the bearings, reduces vibrations and provides high torque. The electric motor is controlled using a high-precision system that was developed for Blu-ray players, which promotes rapid disc rotation and increases the stability of its rotation. Speeds of 33.3, 45 or 78 rpm are supported, which can be selected using the buttons.
The player received a reference disc with notches that allow using a strobe light to adjust each of the three supported rotation speeds (33.3, 45 and 78 rpm) as precisely as possible, which are selected by a pair of buttons located on the upper panel of the case.
In the GR2 model, the motor control signal is generated using a PWM signal generated by ΔΣ (delta sigma) modulation, a high-precision 1-bit digital-to-analog conversion method that is part of signal processing in Technics fully digital amplifiers using the patented JENO Engine technology.
