Tempo Precision Motor Drive

Tempo Precision Motor Drive is based on our reference motor drive utilising some its most advanced control circuit design, implemented to advance beyond the SG motor drive with which the RG-1 and SG-1 Record Players have already had worldwide praise.

 

Peace of mind guaranteed

The Tempo Motor Drive is covered by a 10 year extended warranty. For the extended warranty to be valid, you must register the product with Vertere Acoustics here.

The music we hear when playing vinyl records, in reality, comes from the motor! The motor is the only source of energy in the system.  It is this energy that drives the record past the stylus thus making the music we hear.

Any amount of noise or fluctuation in the drive system will adversely impact on the music.  Detail, dynamics, timbre, timing and musicality are just some of the qualities that will suffer as a result.

The Tempo takes control of the record player motor and provides it with smoother drive with lower noise and lower distortion. Its internal circuit as with the reference motor drive is uniquely microprocessor based providing a pure sine wave in the digital domain and then converted to analogue via an on-board DAC. Two waveforms are derived, a cosine and a sine, which are then amplified using two bridged amplifiers to power the motor.

The Tempo enhances the musical performance and makes the experience of listening to vinyl on the RG-1 or the SG-1 closer to the original master.

Exceptional attention to detail from gold plated PCB, four fully regulated voltage rails powering different sections of the circuit to 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.

High quality mode and speed selector switch allows the unit to be programmed to provide three modes for the white power indicator LED and facilitate easy switching between 33 & 45 rpm.

Motor output is via a high-quality gold plated 6-way locking connector which in turn connects the Tempo to the record player via a dedicated motor link internally utilising two Pulse-R drive cables and a D-Fi LED power cable.
