The RM4200D can be used as a modular, flexible and highly configurable routing system for small and medium-sized applications. Up to 768 input channels and 768 output channels can be routed simultaneously. Example routing applications for the RM4200D include:
On Air switching.
Clean feed routing.
Split-programme operation.
Conference and talk-back applications.
Additionally, DSP processing can be applied to any channel. Some typical DSP processing functions are:
Input and output gain adjustment.
Mono summing, limiter.
FM processing and signal generator.
However, there is a trade-off between the number of available routing channels and the amount of processing in the system. Two basic configurations of the routing system are available and can be selected within the configuration software:
| Router - Mixer (half DSP processing) | Full Processing Mixer - Router | |
|---|---|---|
| MADI input channels | 384 | 192 |
| Discrete analog or digital inputs | 192 | 192 |
| DSP processing channels | 192 | 384 |
| MADI output channels | 384 | 192 |
| Discrete analog or digital outputs | 192 | 192 |
A RM4200D acting as a router system can be controlled from virtually any control module – depending on the actual application. It is possible to control the routing functions from control modules in the mixing console. A range of specially designed control panels is available as well. Thus, the router control can be adapted to different requirements – from simple X-Y operation to special integrated one-button solutions.
Optionally, routing can be controlled using the DHD Router Control Software package, which is available as a separate product. This software runs on a standard Windows PC connected to the RM4200D via a serial port or TCP/IP over Ethernet. The control protocol specifications of the RM4200D are available free of charge. This allows third party developers to integrate a RM4200D system into their system solutions. In fact, several vendors already integrated control functions for DHD systems into their products.
