2.3.1 DSP Frame
The DSP Frame contains the entire signal processing. It is connected to the control desk via
the CAN Bus. Without the control desk, it can be used as an individual device.
5 different types of DSP Frames for the RM3200D are available with 10, 20 or 30 slots and
with or without the capability of using MADI modules.
The DSP Frame contains all signal processing, consisting of the following:
•
10 (RM330-041/ 051), 20 (RM330-042/ 052) or 30 (RM330-053) free slots for input,
output or additional controlling modules
•
Multichannel-modules possible only for the RM330-051/ 052/ 053 basic devices
•
EMC-case 19''/6 U (RM330-042/ 052/ 053) or 3U (RM330-041/ 051) with DSP-
backplane(s) carrying card slots
•
Simple clock generation 48kHz or 44.1kHz with low accuracy clock, high accuracy
clock (+/- 10ppm) available on the Synchronization Module RM330-410 or the
Multichannel Module RM330-421
•
68k-controller with software (1 controller for each 10 slots)
•
RS232/422-interfaces for connecting a PC or controlling applications (1 RS232/422
for each 68k-controller)
•
Power supply 230V or 115V (option) AC (3-pin IEC connector)
•
24 V output and CAN-bus over 24-pin XLR for control panel
•
Power consumption DSP and control desk: approx. 30 ... 120 W (depends on level of
extension)
•
Optional redundant power supply and PFC-power supply unit
The device is by default provided with all components necessary for the basic functions.
This also includes the configuration software for the PC.
The DSP Frame is built with active DSP backplanes, each DSP backplane consists of 10
slots and 4 DSPs. A maximum of 3 DSP backplanes can be connected via the CAN Bus of
the system and via high speed links to build the internal TDM Bus.
On the DSP Frame are slots with different functions available, for details see the graphics
below. The modules are replaced via the rear side of the DSP Frame.
