Roksan RPM Reference Phono Speed Control

Roksan RPM Reference Phono Speed Control

The RPM is the new high-specification, ultra-accurate statement speed control for use with the Xerxes 20+. Consisting of an entirely new and highly advanced digital speed control PCB and audiophile-grade components, The RPM represents a significant upgrade from the previous and long-established reference speed control as featured in the discontinued DX2. Featuring a very high quality crystal speed control system, it maintains pitch perfect speed stability for both 33/45rpm. One new feature of the RPM is its ability - thanks to the new advanced digital speed control PCB – to either increase or decrease the speed (up to 6.25% either way).

The speed adjustment is is very useful where there are mechanical tolerances that affect rotational speed. The speed control system itself is very tolerant of mains input voltage and frequency, being independently regulated from the mains supply.
