The Systembase C530xr digital audio codec has been designed and manufactured to deliver unparalleled performance for professional, real-time audio applications. All models incorporate the fast apt-X Sub Band ADPCM compression system which can deliver a coding delay of only 2.8ms. Additional design features include 24bit analogue and AES audio interfaces. The analogue interface is electronically balanced resulting in a high Common Mode Rejection Ratio (CMRR).

Following a power failure, the C500 series of audio codec can fully reboot to the ready state in approximately 1 second.

The C530xr Audio codec is well suited for implementing cost effective FM and DAB Studio-to-Transmitter Links (STL's), providing up to 22.5KHz Stereo audio over a 384Kbps digital line. The bi-directional auxiliary data port facility can be used to simultaneously send RDS control signals to the transmitter, and receive telemetry information. Alternatively, the auxdata port maybe configured to implement a set of end-to-end contact closures for relay based remote management.

The C530xr backup feature is fully interchangeable with the existing C310xr-x.


AES3 digital audio interface is provided on all models, and is equipped with automatic sample rate conversion to simplify the problems of connecting between a studio reference clock and the ISDN network clock. The AES3 interface is supported via two transformer isolated XLR connectors located on the rear panel.


The C530xr audio codec features a dedicated Ethernet connection reserved purely for WEB management and SNMP control. This dedicated Ethernet connection provides essential isolation from the AIOP streaming connection, simplifying the process connecting the codec to the public internet. The management interface allows each codec to be remotely managed using the various standard web browsers such as IE, Chrome and Firefox. To enable a hassle free experience the WEB server pages have been developed to avoid the use of active x components that may require administrative rights to install on the local computer. In addition, this feature allows the Web manager to function correctly on MAC OS.

All C500 series Codec's have a facility to apply firmware updates via the WEB interface. This feature allows for hassle free maintenance in environments where physical access is not always possible. During the update process the upgrade file, typically 400Kb, will be checked for integrity prior to being flashed into the system. Program disruption is minimized to approximately 20 seconds.

All Systembase ISDN Codec's provide support for SNMP (Simple Network Management Protocol). SNMP allows the codec to be managed by industry standard, third party applications that are capable of monitoring and controlling equipment over LAN and WAN environments. All Systembase ISDN Codec's are supported by the BNCS control platform developed by ATOS and DataMiner developed by Skyline Communications. This feature makes the C530xr audio codec ideal for integration into a automated environments.


A Recent addition to the C530xr audio codec has been the provision for selecting the effective headroom at the Codec's analog interface. By default the analog headroom is set at +12dBu. However, the user may now change to headroom to +18dBu from either the front panel menu or web server interface.
