High Density DSP-based IP Audio Codec32 Channels of Deterministic, Low Latency IP AudioThe Gateway Nexus is a powerful and flexible 32-channel, high-density AoIP codec delivering deterministic, low-latency multichannel audio transport using dedicated and reliable hardware. The Nexus speaks the language of AES67, ST 2110-30, ST 2022-7, RAVENNA, Livewire+, NMOS, Ember+, AES3 and analog I/O as standard. An optional Dante card can also be installed at purchase.OverviewThe Gateway Nexus is ideal for a wide range of deployments and stands out as a compact, powerful and cost-effective alternative to virtualized codec and server-based systems. It can be installed at the broadcast plant, or in hosted data center environments. It is engineered to natively support AES67, ST2110-30, ST2022-7, RAVENNA, Livewire+, NMOS IS-04, IS-05, IS-07 and Ember+. Additionally, a Dante card can be installed at purchase. Compliance with these standards ensures seamless integration into IP-based audio with vendors supporting these protocols.ApplicationsGateway Nexus connects over any IP network and is ideal for:Hosted or data center environments requiring high channel density and low latency connections for live programming and communications applicationsAudio contribution and managing multiple remotesNetwork syndication of programmingMultiple Studio-to-Transmitter LinksMulti-channel links to remote studios (inter-studio links)AoIP OptionsAES67 ReadyNative support out-of-the-box so forget hardware card upgrades, just connect and go!Purchase with an optional Dante card for interoperability with the Dante networksNote: Optional at time of PurchaseNative support lets you connect directly to Livewire+ AES67 networks and exchange audio streams.Native support for RAVENNA, an open technology for stream discovery and advertisement.Supports AMWA NMOS IS-04 and IS-05 for discovery, registration, and control, and NMOS IS-07 Notifications for ST 2110 AoIP streaming, delivering a new level of interoperability and control with networked equipment throughout the broadcast plant.The Ember+ control protocol is supported.ST 2110-30 & ST 2022-7SMPTE ST 2110-30 and ST 2022-7 compliant out-of-the-box.High Density Deployments with Deterministic PerformanceAs the broadcast industry shifts towards centralized and remote production models for live broadcast applications, the codecs DSP-based platform allows broadcasters to upscale infrastructure efficiently. The Nexus is purpose-built for hosted data center deployments, delivering 32 channels of full-duplex high-density AoIP audio. Unlike virtual codec solutions, it provides fully deterministic performance that is predictable, low-latency, and fully hardware-based. The Gateway Nexus will expand your encoding capabilities by providing a centralized hub for all your AoIP streams.Redundancy and Remote ControlMaintain rock solid connections with multiple layers of redundancy and backup including:Dual internal power supplies, dual Ethernet ports and dual AoIP portsSmartStream PLUS hitless packet switchingFuse-IP data aggregationAlternative connection backupAudio file backupIcecast streaming clientFEC and RISTGateway Nexus is fully configurable through an embedded HTML5 Toolbox Web-GUI interface and is also fully controllable using Tielines Cloud Codec Controller. It also supports monitoring and alerts using SNMP and automated alarm notifications using Toolbox software.InteroperabilityAdvanced features and support for a wide range of protocols combine to deliver consistent latency, predictable performance and operational simplicity, making it ideal for state-of-the-art broadcast networks.The Gateway Nexus is interoperable with all Tieline IP codecs and it is also compatible over SIP with all EBU N/ACIP Tech 3326, 3347 and 3368 compliant codecs and devices. The codec is also fully AES67, ST 2110-30, ST 2022-7, Livewire+ and RAVENNA compliant for AoIP streaming. It also supports AES3 and analog I/O as standard. The optional Dante card delivers seamless operation using Dante Controller. It is also AMWA NMOS IS-04, IS-05 and IS-07 compliant for AoIP discovery, registration, connection management, and notifications, simplifying setup and configuration of networked AoIP devices and systems. The Ember+ control protocol is also supported.Flexible Audio DistributionThe Gateway supports 32 mono or 16 stereo full-duplex audio streams. Gateway also supports flexible multi-unicasting and multicasting configurations for audio distribution.Stream up to 32 different multi-unicast audio streams to up to 80 endpoints in total.Stream up to 32 different multicast audio streams to unlimited endpoints over compatible networks.Main Features:Analog, AES3- Support for AES67, plus AES3 (AES/EBU) and analog I/O optionsHTTP Streaming- Support for Icecast or Shoutcast HTTP streamingSIP and IP Intercoms- SIP EBU Tech 3326, 3368, and EBU Tech 3347Dual AoIP Ports- Stream AoIP from dual portsSD card- SD card slot for firmware upgrades, storage and SDIOAlarms- Silence Detection, PSU Failure, Lost connection, Temperature, AES Input, AES Reference, SNMP and moreDual Internal Power Supplies- Dual power supplies provide backup if one failsDual Ethernet Ports- Connect using different Telcos for diversity using SmartStream PLUS redundant streamingModule Compatible*- Module slot for future hardware innovationsMulti-Unicast- Support for multiple simultaneous multi-unicasts over compatible IP networks to up to 80 endpointsSimultaneous Multicast- Support for multiple simultaneous multicasts over compatible IP networks to unlimited endpointsPhase-locked streaming mode- Stream 4, 6 and 8 digital channels in phase-locked mode to deliver live content in both stereo and surround sound formats (LC-AAC only)Internal SSD Storage- Internal Storage supports record, store and forward use cases for network syndication applications*Expanded Backup Options- Multiple levels of power, audio and network redundancy with dual Gigabit Ethernet ports, dual internal power supplies, automated audio silence detection and IP network backup solutionsSpecifications:General- Dimensions: 19 x 1 3/4 x 11 13/16 [482mm (W) x 44.45mm (H) x 300mm (D)] excluding rear connectors- Weight: 4 Kg / 8 lb 13.100 oz- Power: Dual AC 90-240V IEC power inlets;
