Yamaha DCH8 is a Digital Controller Hub with 8 ports. The DCH8 divides the control line from host devices such as the Yamaha MTX/MRX series into up to 8 lines. It also allows for a flexible system structure, with a combination of star connections and daisy chain connections as a repeater between the host device and the control panels. DCH8 supports various ways of installation with screw holes equipped for mount fittings on the side and in the rear.
