Reference Phono Speed Control RPM

About this product

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 signi cant 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). This is a very useful addition for customers in areas or countries for unstable or poor currency voltage to attain the exact, correct speed.
