Road Ready RRM19 Created for the Pro’s, the RRM19 mixer case is made for the journey and built to hold strong in high stress situations. Designed to fit 19" mixers including the Mackie 1604 and 1642, the RRM19 features a heavy-duty removable, latchable cover and adjustable foam lining for the perfect custom fit. We also created the RRM19 with a unique low profile base design that allows you to access the mixer’s rear connection panel without removing your mixer from the case. Tougher than the pavement! That’s the idea.
