The xNode2 lightweight, half-rack, high-performance AoIP interface from Telos Alliance is loaded with advanced features and capabilities. Theyre fanless, which means theyre noiseless too. Versatile mounting options let you deploy two xNode2s in just 1RU of rack space, or on ceilings, walls, and under counters with an available wall-mount kit. xNode2s have studio-grade audio performance specs and offer redundant power options using AC mains and PoE+. Dual 1000MB network interfaces support SMPTE 2022-7 seamless protection switching of RTP datagrams. xNode2s are Livewire+ AES67 compliant, including Livewire advertisement and Session Announcement Protocol (SAP).GPIO xNode2 provides 6 general-purpose logic ports for machine control of studioperipherals audio devices, loudspeaker muting relays, signal lamps, etc. each with 5opto-isolated inputs and 5 outputs. A logic port can be associated with any audio inputor output and routes control data transparently along with the audio.Main Features:Fanless design with cast-aluminum heat sinks is completely silent in-studio. Front-panel heat sinks are cooled by ambient air, not rack air, eliminating overheating worries.xNode2s are universal translators that support that support a huge installed base of Livewire+ hardware as well as audio streams from other AES67-compliant devices.High-resolution front-panel multi-function LCD color display meters inputs and outputs or GPIO status and gives software and other status information.Power-efficient: xNode2s use just 16 Watts each.Exclusive redundant power plan uses AC and Power over Ethernet plus (IEEE802.3at) supplied by compliant Ethernet switches. Two front-panel LED glow when AC mains power is used and when PoE+ is used.SMPTE 2022-7, Seamless Protection Switching of RTP Datagrams: Dual NICs allow you to stream to separate network branches for RTP audio redundancy. Automatic failover to the available RTP stream.Built-in Syslog server with configurable event filter and external logging.Synchronize your AES master clock to a designated xNode2 AES/EBU input to keep all of your AES streams synchronized to the house clock.xNode2s use premium components, including rugged cast aluminum faceplates and heat sinks, high-resolution LCD displays, bulletproof power supplies designed for high availability telecom applications, and studio-quality SRCs with recording-studio specs.I/O connections via industry-standard RJ-45 audio connectors or high-density DB-25 connections, both available prefabricated and ready to attach in seconds.Versatile mounting options: Use freestanding, rack singly or side-by-side in 1 RU, or wall-mount using an optional surface-mount kit.Analog xNode2 inputs can be configured to supply four stereo audio channels or eight true mono channels. Outputs support the same variety of selections, easily selectable in software via the built-in web interface.On the Analog, AES/EBU, Mixed Signal, and Microphone xNode2s, a fully configurable mixing matrix allows for the mixing of both physical and network inputs, stream conversion, and a multitude of other unique solutions.SAP supportSpecifications:Microphone PreamplifiersSource Impedance: 150 OhmsInput Impedance: 4k Ohms minimum, balancedInput type: Line or MicrophoneMicrophone PreAmp Gain: Adjustable, 14 dB to 68 dBPhantom power: +48VDC, switchableAnalog Line InputsInput Impedance: >40k Ohms, balancedNominal Input Range: +4 dBuInput Headroom: 20 dB above nominal inputAnalog Line OutputsOutput Source Impedance: <50 Ohms balancedOutput Load Impedance: 600 Ohms, minimumNominal Output Level: +4 dBuMaximum Output Level: +24 dBuDigital Audio Inputs and OutputsReference Level: +4 dBu (-20 dB FSD)Impedance: 110 Ohm, balancedSignal Format: AES3 (AES/EBU)AES3 Input Compliance: 24-bit with sample rate conversionAES3 Output Compliance: 24-bitDigital Reference: Internal (network timebase) or external reference 48 kHz, +/- 2 ppmInternal Sampling Rate: 48 kHzInput Sample Rate: 32 kHz to 192kHzOutput Sample Rate: 44.1 kHz or 48kHzA/D Conversions: 24-bit, Delta-Sigma, 256x oversamplingD/A Conversions: 24-bit, Delta-Sigma, 256x oversamplingFrequency Response: Any Input to Any Output: +/- 0.5 dB, 20 Hz to 20 kHzLatencyAnalog Input to Analog Output, 4.5ms including network, converters, and mixing processDigital Input to Digital Output, 3.5ms including network mixing engine (ASRC off) Dynamic RangeAnalog Inputs to Analog Outputs 104dB referenced to 0dBFs, 111dB A-weightedAnalog Inputs to Digital Outputs 110dB referenced to 0dBFs, 113dB A-weightedDigital Inputs to Analog Outputs 110dB referenced to 0dBFs, 115dB A-weightedDigital Inputs to Digital Outputs 126dBEquivalent Input NoiseMicrophone Preamp: -130 dBu, 150 Ohm source, reference -50 dBu input level Total Harmonic Distortion + NoiseMic Pre Input to Analog Output: < 0.005%, 1 kHz, -36dBu input, +18dBu outputAnalog Input to Analog Output: < 0.005%, 1 kHz, +18dBu input, +18dBu outputAnalog Input to Digital Output: < 0.004%, 1 kHz, +18dBu input, -6dBFs outputDigital Input to Analog Output: < 0.004%, 1 kHz, -6dBFs input, +18dBu outputDigital Input to Digital Output: < 0.0003%, 1 kHz, 0dBFs Crosstalk Isolation, Stereo Separation and CMRRAnalog Line Stereo Separation: < -90dB, 20Hz to 20kHzAnalog Line Input CMRR: < - 85dB, 20Hz to 20kHzMicrophone Input CMRR: < -70 dB , 20 Hz to 20 kHzPower Supply AC Input: Auto-Ranging Supply, 95VAC to 260 VAC, 50Hz to 60Hz, IEC Receptacle, Power Consumption: 16 WattsOperating Temperatures: 0 degree C to +40 degree C, <90% humidity, no condensationDimensions: 8.5 (22 cm) wide; two may be mounted side-by-side in a standard 1RU rack space; 1.72 (4.4 cm) height, 11.75 (30 cm) depthRegulatoryNorth America: FCC and CE tested and compliant, power supply is UL approved.Europe: Complies with the European Union Directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS), as amended by Commission Decisions 2005/618/EC, 2005/717/ EC, 2005/747/EC (RoHS Directive), and WEEE.Click here to see the GPIO xNode2 manualClick here to see the latest xNode2 release notes
