RMI4 remote controls are intended for use with iFlex DSP mixer products. These devices provide a friendly, intuitive and configurable interface for the end-user to control elements and functions of an iFlex system. The controls can be configured for the particular needs of the user in any specific application. Combinations of these control panels can be connected daisy-chain fashion via standard EtherNet cable. The devices are powered over the cable connecting to the mixer and no local power sources are needed. Communication from the remote control(s) to the mixer is by reliable RS-485 protocol.
