Vertere Tempo 'digital' PSU

Vertere have released the Tempo motor drive for its range of turntables. Tempo is a new generation' digital' motor drive, unlike its sibling, the analogue SG motor drive. Sitting a little above the well-established SG at £2,850, $3,995 and €3,598, Vertere expects Tempo to sell with the SG-1 and RG-1 turntables with SG-1 tonearms. MG-1 customers will also migrate to Tempo over time. Given the performance improvement it is unlikely to be too long.

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 the music.  Detail, dynamics, timbre, timing and musicality are just some of the qualities that will suffer as a result.

Tempo Precision Motor Drive derives from Vertere's reference motor drive. It uses some of the reference drive's most advanced control circuit design. It 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, and 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. 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 connector connects the Tempo to the record player via a dedicated motor link that internally utilises two Pulse-R drive cables, and a separate D-Fi LED power cable.
