The Systembase C530ip IP audio codec has been designed and manufactured to deliver unparalleled performance and reliability for professional real-time audio applications over X.21, ADSL, IP and Satellite. The C530ip incorporates the fast apt-X Sub Band ADPCM compression system which can deliver a coding delay of only 2.8ms, in addition to L24, L16, G.722, G711, PCMA and PCMU.

The C530ip is fully compatible with the existing C310xr-x codec when operating over X.21 circuits. Additional design features include 24 Bit analogue and AES audio interfaces. The analogue interface is electronically balanced resulting in a high Common Mode Rejection Ratio (CMRR) for a significant improvement in performance.

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

C530ip IP (AoIP) Codec


Systembase IP (AoIP) codec has been designed to enable multiple simultaneous connections from a single unit. A connection can be made or broken without disrupting other connections that may already exist. When making a connection to a remote codec, the user can specify the audio to be duplex, receive only or transmit only. If the receiving codec is not able to implement the requested audio mode due to a conflict with an existing connection, Automatic Negotiation will take place to provide a suitable operating mode. Automatic Negotiation allows the remote codec to connect without any prior knowledge of the local codec's connection status.

In the event of power failure the C530ip can re boot, negotiate and restore an IP (AoIP) connection to its streaming state in approximately 10 seconds. This feature is perfect when the codec is being used for commercial applications such as transmitter links or live commentary.

C530ip SNMP and BNCS

C510ip codec monitor


New for 2015 is a monitor tool that allows all Systembase C500 series codecs to be monitored from a browser window. Each codec icon allows the user to monitor the audio input and output levels together with the “SYNC” status of the codec. A simple click of the “OPEN CODEC” tag will take the user directly to the associated codecs’s web browser interface.


The Group Security ID feature provides a very useful mechanism for securing a group of IP codec's. This feature is enabled by entering the same 8 digit ID code into all participating codec's. The ID code is then used by the codec to automatically reject all packets that do not have a matching code.

NEW for 2016:- SIP

The Session Initiation Protocol (SIP) is a communications protocol for signaling and controlling multimedia communication sessions. The inclusion of SIP on the C510ip provides a baseline of compatibility with most manufacturers of IP based Audio equipment. This would include Codecs, tablet based App's, mobile phones and desk top computers.


IP connections are not always 100% error free and occasionally the IP network will loose a packet of data. In the case of a typical broadband ADSL connection packet loss can be fairly frequent. Forward Error Control (FEC) facilitates the transmission of additional information that allows the receive codec to automatically re-create the missing packet from data contained within the neighboring packets. The Systembase FEC process does not require any additional IP communication and consequently minimises the end-to-end audio delay.

NEW for 2016:- SIP Proxy

The proxy server is an intermediary entity that acts as a and a host for the purpose receiving and making IP based calls. The C500 series IP codec can register on a proxy server using a secure username and password. Once registered, the codec can make and receive calls with other registered devices and PSTN based telephones. A subscription based Proxy provider will allocate you a telephone number that can be dialled from anywhere in the world via another proxy provider or standard PSTN device. This gives users the ability to connect to each other using just a telephone number.


The C530ip IP codec is ideally suited for implementing a Studio-to-Transmitter Links (STL's) for FM and DAB radio, providing up to 22.5KHz Stereo audio over a X.21 digital leased line or IP network.

To maintain program continuity, the C530ip automated IP (AoIP) backup is initiated on failure of the X.21 signal path. Restoration of service back to X.21 occurs automatically once the fault condition has cleared.

All Systembase IP (AoIP) codecs 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 IP (AoIP) Codec's are supported by the BNCS control platform developed by ATOS and DataMiner developed by Skyline Communications. This feature makes the C530ip audio codec ideal for integration into a automated control room environment.


A Recent addition to the C530ip IP (AoIP) codec has been the provision for selecting the effective headroom at the codecs 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.


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 C530ip IP audio codec features a dedicated Ethernet connection reserved purely for WEB management and SNMP control. This dedicated Ethernet connection provides essential isolation from the IP (AoIP) streaming connection, simplifying the process connecting the codec to the public internet. The management interface allows each codec to be remotely controlled 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 codecs 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.
