For analog enthusiasts requiring absolute speed stability and pitch control from their turntable. Housed within a shielded metal case, free from electromagnetic interference and vibration, resides advanced high precision Quartz-generated electronic speed generation circuitry. Designed to provide ultra-stable 33-1/3 and 45 rpm speed regulation to your turntable with plus-minus pitch control monitored by a digital display (78 rpm possible with pulley change). This Quartz generated sine wave is filtered, mains-decoupled and voltage regulated for the ultimate in speed stability and regulation. All functions are microprocessor controlled for simple and precise operation.
