Tascam MMR-8 Owner’s Manual • Chapter 2 • Installation

  Installing Multiple MMR Units

Multiple units can be mounted one on top of the other when forced air rack ventilation is provided. A one-
inch clearance is required on both sides of the MMR-8. In facilities with raised computer room-style
flooring, a ventilation opening in the floor is recommended. In no case should the internal rack
temperature ever exceed 110 degrees Fahrenheit (43 degrees Centigrade) during normal operation (as
measured at the rear of any of the MMR-8s in the system).
