Arxiduc Audio Co. Ltd. was established in Yokohama, Japan, in 2013 to serve the PA and sound reinforcement market. The company maintains a fleet of Yamaha mixing consoles, including CL and QL series models, and in 2016 acquired Yamaha’s flagship RIVAGE PM10 Digital Mixing System with a CS-R10-S control surface. A year later, a CS-R10 control surface was added to handle larger applications, giving Arxiduc Audio the flexibility of operating two RIVAGE PM10 configurations. We asked chief engineer Hiroaki Otsubo and technical support engineer Osamu Sato about their decision to adopt the RIVAGE PM10, and how they like it.
