•
DSP Function Control Software (RM330-051) for easy controlling of the audio
processes in a channel
•
Mixer Control Software (RM330-0553)
You do not need the PC software tools for the “normal work” – the RM3200D has no PCs
inside and works completely without any PC.
For both main hardware parts we have several different modules that will be described in
the next sections.
The DSP Frame of RM3200D can provide a total of 264 input channels: up to 96 mono
channels over A/D-converters or digital input modules, plus 3 multi channel inputs (MADI or
proprietary formats with up to 56 channels for each module). It can output up to 96 mono
channels over D/A-converters or digital outputs and 3 multi channel outputs (56 channels
each).
Due to the compact size of the control desk, the RM3200D can be functionally integrated
into a workplace. The desk consists of a main module and fader modules. The main module
contains 2 monitor level controllers, 49 keys, an ASCII display and a rotary knob for
adjusting settings. The fader module is equipped with 4 faders, 20 keys and 4 ASCII
displays.
A maximum number of 20 faders per mixer is possible (5 fader modules).
The fader modules and the main module are closed modules with their own microcontroller
logic, thus offering the opportunity to be built in separately. They are interconnected only via
one cable using 4-pin XLR-connectors (+24 V, CAN+, CAN-, GND).
The DSP Frame contains all signal processing, consisting of the following:
•
DSPs
•
A/D- and D/A-converters and microphone amplifiers
•
Digital in- and outputs
