Reliable - Simple - Flexible

Welcome to the Opus-Two Instrument Control System (ICS). Opus-Two is used by organs around the world, providing owners with unsurpassed convenience, flexibility, customization, and value.  Opus-Two ICS is currently installed on the two largest pipe organs in the world - The Wanamaker Organ at Macy’s Center City Philadelphia and The Auditorium Organ at Boardwalk Hall in Atlantic City. But the vast majority of the control systems we ship are for church organs. Because Opus-Two is scalable without sacrificing speed, it is perfect for instruments of all sizes.

Whether you have browsed to this site to learn more about the system, download a manual, or request support, we hope you enjoy browsing our website.  If you ever have any questions, never ever hesitate to contact us!
