New RAVENNA-enabled products unveiled at IBC 2019

    As the migration to IP workflows continues to gain momentum, the announcement of RAVENNA-enabled product burgeons accordingly. Now the de facto AoIP transport technology for the broadcast industry, RAVENNA is pleased to announce product launches from several RAVENNA partners including Lawo, Qbit, 2wcom, RTW and DirectOut.


    Lawo (8.B50) introduces the PowerCore MAX AES67 mixing engine, a powerful gateway between legacy audio formats and standards-based IP media networks with integrated DSP capabilities in a space-saving 1U chassis. With the ability to support up to four mixing consoles, PowerCore MAX offers 128 dual-redundant MADI channels and 128 RAVENNA/AES67/ST2110-30 channels plus an internal 1920 x 1920 routing matrix. Other features include 80 user-defineable summing busses and 96 channels of DSP plus dual front panel SFP connectors for ST2022-7 Seamless Protection Switching. Eight expansion slots of the rear of the device enable the choice of extra mic, analog, AES3, RAVENNA/AES67 and Dante I/Os as required.


    Also from Lawo comes AES67 Stream Monitor, the world’s first AES67 stream monitoring software. AES67 Stream Monitor displays detailed information for as many as 16 user-definable audio streams, each of which can contain multiple audio channels. The main display presents audio levels and alarm indications at a glance for all monitored streams; selecting an individual stream display allows users to do a “deep dive” to discover detailed stream information. Further functions include the ability to audition AES67 streams using the PC sound card; monitoring of two Ethernet NICs simultaneously for true ST2022-7 compatibility; monitoring of packet drop, jitter and data errors; SDP data access for each monitored stream; LUFS metering including alarms for silence-sensing, under-level or over-level alerts with user-definable thresholds.


    Ross Video (11.C10) launches its NWE-IP, Nielsen Watermark Encoder for IP networks. The solution delivers Nielsen-certified watermarks encoding for SMPTE2110/AES67 streams on COTS Linux computing. The NWE-IP is built upon Ross Video’s latest release of the BACH Virtual SoundCard (VSC), which is one the many products in the family of BACH OEM Developer Solutions. The BACH VSC is a Linux-based SDK that enables audio applications, such as NWE-IP, running on a COTS Linux server to connect with ease to AES67 and SMPTE ST2110 audio senders and receivers using SAP, and RAVENNA open control protocols supporting up to 64 audio channels and 8 low latency bi-directional streams.


    Digital audio transport specialists Qbit (8.E49) debut several new products this year: Firstly, the Q880-STREAM RAVENNA/AES67-compliant multi-channel Internet Radio Streaming Encoder which encodes up to 50 stereo programs and generates up to 280 outgoing streams in Icecast and HLS (HTTP Live Streaming). Qbit’s reliable, embedded technology in a compact, 1U design ensures extremely low encoding delay, in a future-proof format for seamless integration of networked audio into existing infrastructures.


    In the same series, the Q880-DVB RAVENNA/AES67 multi-channel DVB audio encoder with RAVENNA/AES67, Dante and MADI interfaces enables transport of up to 64 stereo programs to the DVB audio encoder via a single standard IP cable. It supports all of the common audio encoding algorithms such as MPEG-1 layer 2, AAC-LC, HE-AAC-v1/v2 and many more.


    The Q822 AES67 interface connects analog or digital (AES3) audio interfaces with AES67 IP audio networks. Incoming audio signals are coded into RAVENNA/AES67 and can then be fed into IP audio networks over redundant IP interfaces.


    Finally, Qbit unveils the QUARION RAVENNA Interface Series which interfaces AES3 and analog audio with RAVENNA/AES67 networks. Easy to use, cost effective and compact, QARION offers straightforward ingress, egress and monitoring of RAVENNA/AES67 streams in audio networks and plug-and-play integration of legacy audio equipment into RAVENNA/AES67 networks.


    QARION is available in four flavours:

    • QARION Analog In: 2x Analog Inputs (XLR-F)
    • QARION Analog Out: 2x Analog out (XLR-M)
    • QARION AES3 In/Out: 1x Digital Stereo Input, 1x Digital Stereo Output (AES3)
    • QARION Headphone: Headphone Output (6,3 mm) + 2x Analog Output (XLR-F/M), LCD + jog wheel


    2wcom (8.E78) reveals its 4audio series of modular, Linux-based IP audio solutions that are available as hardware or software. Products include the IP-4c 4-channel codec, the IP-8e 8-channel IP/MPEG encoder and the MoIN Multimedia-over-IP network server that support studio-to-studio, and studio-to-transmitter links as well as a multitude of cross-media tasks. Maximum compatibility in mixed networks is ensured thanks to support of RAVENNA/AES67/ST2110-30, Livewire+, Dante, EBU N/ACIP or SRT interfaces and cross-protocol conversion as well as SMPTE 2022-7, NMOS and Ember+. All major codecs are also supported including PCM, Opus, AAC profiles (even AAC xHE), enhanced aptX, Ogg Vorbis and more.


    The newest RAVENNA partner, RTW (8.D89) introduces the very latest incarnation of its TouchMonitor range of audio monitoring and loudness metering screens. Following the recent introduction of a DanteTM interface for the TM7 and TM9 units, the latest versions shown for the first time at IBC 2019, offer full AES67 compatibility thanks to the integration of a native RAVENNA interface.


    Last but not least, our friends at DirectOut (8.E85) have launched a powerful new RAVENNA/AES67 OEM module for integration into third party devices. Fully RAVENNA-, SMPTE ST2110-30/31- and AES67-compliant, the module provides 128 x 128 channels in up to 32 network streams. Offering ultra-low latency and a 44.1 to 192 kHz sample rate, it supports all ST 2022-7 classes in a compact, mini-PCI form factor. It has built-in PTP Grandmaster capability and also provides mDNS and SAP stream announcement.
