Rane NM 84 Operator's Manual

uick Start
Why is it that the hardest thing about writing the Quick Start is the opening line? What I want to say is, “First, design the
network.” Only that’s hard to say with a straight face — but if you are going to jump right into this thing without reading all of
our hard work, then that’s where you begin. By designing a network. Okay, that works...let’s move on.
A dedicated network for CobraNet audio is recommended, but not required when using switched networks. The NM 84’s
CobraNet technology utilizes standard 100Base-T Ethernet hardware. For CobraNet and network design assistance and a list of
other CobraNet licensed and tested devices, visit
