Phase-locked multichannel AoIP codec for surround sound


The IP-8m eight-channel AoIP codec allows for the transmission of eight digital mono-channels in phase-locked mode (8.0, 7.1, 6.0 and 2.0, 5.1 and 2.0 or 4.0 and 4.0). Radio stations can provide their listeners live content in both stereo and surround sound quality. The multichannel codec enables users to feed live contributions into large or international broadcast networks via surround routers.

Multi-format audio coding: Suitable for audio broadcast applications like live concerts and studio-to-studio connections, operators can select from audio algorithms, including Dolby Digital (DD or AC-3), Dolby Digital Plus (DD+ or E-AC-3), PCM, E-aptX and AAC.

High compatibility: The IP-8m is compliant with standards such as EBU Tech 3326, AES67, Ravenna, Livewire+ or SMPTE 2110 to ensure compatibility with third party products.

Pay as you grow: All soft- and hardware components are individually combinable. The scalability from one to four audio channels using software licences gives you flexibility in planning your network and reducing your costs.

Transmission robustness: Features like two internal or external power supplies, error correction mechanisms such as Pro-MPEG FEC or SRT Secure Reliable Transport, streaming redundancy by Dual Streaming) and backup by alternative audio sources, ensure 24/7 operation.

Smart management: Users can configure all parameters via a web interface or remotely via SNMP, Ember+, JSON, HTTP, FTP, Telnet or NMS. The Easy2connect SIP phonebook simplifies intercommunication for remote connections by negotiating protocols and codec algorithms with just one click. The protocols for synchronization NTP, PTPv2, or 1PPS allow a synchronized playout down to 1 µs.
