Tempo Motor Drive Power Supply

The Technical Bit

Tempo Precision Motor Drive derives from Vertere’s reference motor drive. It uses some of the reference drive’s most advanced control circuit design.

Tempo controls the record player motor and provides a smoother drive with lower noise and lower distortion. As with the reference motor drive, its internal circuit is uniquely microprocessor-based. It provides a pure sine wave in the digital domain, converted to analogue via an onboard DAC. Two waveforms are derived, a cosine and a sine, amplified using two bridged amplifiers to power the motor.

Exceptional attention to detail, including a gold-plated PCB, four fully regulated voltage rails powering different circuit sections, and carefully selected components ensure in-control and ‘clean’ final delivery of power to the motor. The entire digital, microprocessor and DAC, circuitry is first shielded by copper foil, and then the whole PCB is secondary shielded using a stainless steel shield plate.

Features

A high-quality mode and speed selector switch allow the unit to be programmed to provide three modes for the white power indicator LED and facilitate easy switching between 33 &45 rpm.The motor output high-quality gold plated 7-way locking connect or connects the Tempo to the record player via a dedicated motor link that internally utilizes two Pulse-R drive cables, and a separate D-Fi LED power cable.
