The Digital Audio Mixing and Routing System RM4200D is especially designed for applications in Broadcasting. It has been designed from the ground up to be a reliable and easy to use tool for a broad range of users. No matter if journalists in self operating studios or engineers in complex control rooms or OB vans are using the RM4200D – they will find that it lets them concentrate on the job at hand without having to worry about operating the equipment.
The RM4200D is a highly modular system with versatile hard- and software options. Its powerful Audio Engine and its flexible Control Engine are fully configurable with an easy to use configuration software. Thus, the system can be adapted to many different applications without sacrifying reliability and ease of use.
It can equally be used for:
On Air and Continuity studios; both for self operation or control room operation, with one ore more studios.
Routing, networking, On Air switching and talk-back applications.
Pre production units for newsrooms, recording, editing, video post production, dubbing.
OB-Van and other field applications.
The RM4200D uses a high-performance Audio Engine with enough capacity for routing and processing many channels even in complex situations. A fully configured RM4200D system provides the following audio resources:
48 stereo summing buses.
768 internal routing channels.
Up to 192 discrete input channels and 192 discrete output channels, either analog or digital.
Up to 6 MADI ports, depending on the actual configuration of the system. Each MADI port can use 64 input channels and 64 output channels simultaneously.
If desired, the RM4200D can provide both input microphone processing as well as output processing for the On Air signal. Therefore there is no need for separate outboard gear any more.
A very powerful clean feed system provides up to 30 clean feeds with additional functions like talk back, pre fader conference mode (preperation mode) and flexible output routing.
The RM4200D is the first digital audio mixer of this class where the internal signal processing uses 32bit Floating Point DSPs (Analog Devices SHARCs). Internal over modulations sometimes occurring in devices with fixed point processors are almost impossible, since the available dynamics range is greater than 1000 dB(!).
All digital inputs use asynchronous sample rate converters. Thus, digital consumer devices and non-synchronizable professional devices can be digitally connected to the system.
The RM4200D uses a special real-time operation system running on several micro controllers. There is no PC-based system inside and it works completely without any PC.
The configuration software runs on standard Windows(TM) based PCs. However, this PC is not needed to run the RM4200D from day to day – it is only needed for setting it up.
