Applications

  • Backup
    Backup options can be configured within one network or cross network, e.g. from IP to IP, from IP to ISDN, etc. depending on the available network interface cards.
  • Gateway
    Gateway functions allow the bridging of formats and interfaces, depending on availability of algorithms and network interface cards, e.g. from an 2x64kbps Layer 3 ISDN call into an Axia Livewire IP protocol
  • Simple Answering machine
    Incoming calls can be recorded in different formats and kept on internal or external storage media, including SSD cards. They can also be send to external servers and disk capacities via FTP. The recorded signal can be incoming, outgoing or both.
  • Logging
    Time logging is available as well, as an extension of the answering machine. Time stamps and further metadata archiving is as simple to admin as the audio format and storage organization.
  • Multi-SIP
    Audio connections via IP are moving more and more to SIP as SIP servers are becoming more available. Multi SIP allows use of a variety of SIP servers within one product, e.g. 2 transmissions via SIP server 1, 4 transmissions via SIP server 2, etc.
  • Combination of applications and extensive applications packages
    The CENTAURI IV 3001 can combine the above mentioned applications and do backup, gateway and recording/logging at the same time.
  • PLEC - Packet Loss Error Concealment
    Real-time audio data streamed over unreliable IP networks, such as the Internet, may encounter losses due to dropped packets or late arrivals. PLEC detects and prevents dropped packets.
  • Voice Options (Echo Cancellation)
    Voice options on MAYAH codecs include noise suppression, acoustic echo control, and automatic gain control. The CENTAURI IV 3001 can combine the above mentioned applications and do backup, gateway and recording/logging at the same time.



CENTAURI IV 5000 – The Customizable Toolbox for Professional Broadcasters with High Standards

Multichannel Audio Codec and Gateway for Studio Applications

64 channel scalable audio transmission solution, 19", 2RU, redundant PSU, several Codec Formats, linear, Dual Ethernet


There's hardly any transmission challenge our CENTAURI IV 5000 can't handle. Anything from streaming, scouting, extensive error correction /concealment to format conversion, consider it done. The CENTAURI IV 5000 is THE solution when it comes to handling multiple scalable channels with up to 128 mono or 64 stereo programs combined in one unit. Applications range from an answering machine for scouts, reporters and journalists, to a communication center for e.g. major sports events and others situations featuring extensive data traffic. It is a highly flexible algorithm tool box, supporting all relevant IP protocols including AoIP and offers wide compatibility. If you need to connect to 3rd party hardware or software codecs or apps, the CENTAURI IV 5000 is your best choice. Beyond backup and standard gateway functions, incoming IP/ISDN calls can be transferred to e.g. Livewire or, as a file, to and from a broadcast server. For your broadcast challenges, MAYAH's CENTAURI IV 5000 is the solution.

The CENTAURI IV 5000 is a customizable toolbox that can be adapted to your needs. You need more channels? Then the proven 4th generation CENTAURI IV 5000 is the answer. It offers 8 channels which can be expanded to 16 in a variety of formats or 64 channels via MADI. You need ISDN? No problem! Choose between BRU ( 8 x B channel) or PRI (up to 30 x B channel). It also offers Multi SIP, Gateway, scalable error handling, and is ready for interaction with mobile devices and more.

Simply let us know your requirements and we will build your very own CENTAURI IV 5000.

Applications

  • Extensive Backup The backup options for the CENTAURI IV 5000 go far beyond those of other models due to the number of channels and the available computational power: 4 sub codecs are backed up from IP to Livewire, 3 sub codecs are backed up from IP to ISDN, 21 sub codecs are backed up from IP to IP changing format at the same time.
  • Extensive Gateway
    Gateway options are likewise ahead of other models for the same reasons: 4 sub codecs are converted from G.722 ISDN to Axia Livewire, 7 sub codecs are converted from AAC HEv2 IP to ISDN Opus, 11 sub codecs are backed up from IP to IP changing the format at the same time.
  • Extensive Answering machine
    A variety of broadcast participants, whether journalists, scouts, traffic reporters or others may require extensive answering machine functionality. For instance using MOBIPhone to call a CENTAURI IV 5000 with the HQ answering machine application. Up to 60 channels can be handled, in combination with multi SIP and other features.
  • Extensive Logging
    Similar to the extensive answering machine feature, the logging application provides more expansive functionality as far as time and events are concerned. It is also possible to divide the long logging recordings into parts. In addition, it can be supported by an encryption method for security reasons. Only authorized people with the appropriate code are able to read the data.
  • Multi-SIP
    Audio connections via IP are moving more and more to SIP as SIP servers are becoming more available. Multi SIP allows use of a variety of SIP servers within one product, e.g. 2 transmissions via SIP server 1, 4 transmissions via SIP server 2, etc.
  • Combo-apps
    Various applications can be combined in order to achieve an even higher performance. It is recommended to contact the vendor for specific combinations to get an evaluation of your requirements.
  • Error Concealment
    In case of packet losses, it is important that the audio signal is somehow repaired. It does not have to be identical to the original signal, like in error correction method applications, but the subjective impressions should always be good. MAYAH has implemented a scalable error concealment scheme which applies different error concealment techniques depending on the type of package loss.
  • Voice Options (Echo Cancellation)
    Voice options on MAYAH codecs include noise suppression, acoustic echo control, and automatic gain control. The CENTAURI IV 5000 can combine the above mentioned applications and do backup, gateway and recording/logging at the same time.
