The Big Selection: Matrix Cards for Every Application
An extensive range of matrix cards is available for configuring an oratis intercom system. While providing largely identical functionality, they differ mainly in their port configuration. Whether CAT5, video, or optical cable, balanced analogue, digital, or Voice over IP – your application rules your selection.
All matrix cards feature:
- Audio routing using a flexible and extensible FPGA configuration
- Audio in broadcast quality: 48kHz sample rate, 24bit word length (with internal 32bit processing)
- Transparent routing of digital signals
- Optional DSPs for I/O-signal processing

Processing
Signal routing on all oratis matrix cards is processed by a modern FPGA processor. In contrast to hardwired signal paths, all processing stages and signal routes are implemented in software. Thus, oratis systems offer 
unprecedented flexibility and future-proofing. All input and output signals can either be transparently routed on the matrix cards or routed via optional DSP modules. Functions available include gain control, filters, dynamics and delays.
FPGA: Flexible Signal Pathways
In all new oratis boards, Field Programmable Gate Arrays, (FPGAs), replace conventional signal paths. Instead of designing the signal pathway with copper connections in several layers on a circuit board, the logic modules of the FPGAs calculate the required signal path. The big advantage: Changes can be implemented quickly and at low cost by simply re-programming the software. Expensive and time-consuming design of complex new circuit boards can be avoided. Thanks to this technology you can be sure that the oratis system can always match future requirements! Internally an FPGA chip is based on parallel processing and can compute many channels simultaneously. This also offers the advantage of further increasing the packing density. The high speed processing with constant and short computation time is also very beneficial. For these reasons, FPGAs are already established as the standard in other hi-tech markets such as telecommunications and the Internet.
