The Gateway-4 is a powerful DSP-based 1RU IP codec designed for live remote broadcasting applications, as well as STL or SSL links. The Gateway-4 also includes support for AES67, ST 2110-30, AES3 and analog I/O as standard, and an optional WheatNet-IP card.The Gateway-4 supersedes and replaces the popular Merlin and Genie STL audio codecs. It supports 4 full-duplex audio channels in 1RU to expand channel density by one when compared with these codecs. The Gateway-4 provides two stereo connections, or one stereo and two mono connections, or up to 4 mono full duplex connections. The Gateway-4 also supports multiple unicasting to up to 20 endpoints and multicasting. Customers with higher channel requirements will gravitate towards the Gateway-8/16 multi-channel codec.For larger networks, the Gateway-4 is ideal for transmitter sites, remote trucks or rack-mounted remote kits. For affiliates and smaller stations it can be used to transport studio-to-studio links, or a stereo studio-to-transmitter link signal plus another stereo connection, or dual mono connections for remotes.Main Features:Dante CompatibleAnalog, AES3: Support for AES67, plus AES3 (AES/EBU) and analog I/O options.Wi-Fi (USB Dongle): Expand your network options and connect over Wi-Fi networksSIP 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 SDIODual USB ports: Dual USB ports support firmware upgrades, storage and Wi-Fi modems.Dual 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 ISDN network compatibility, and for future hardware innovationsMulti-Unicasting: Support for multi-unicasting to up to 20 endpointsMulticasting: Support for multicasting over compatible IP networks to unlimited endpointsAlarms: Silence Detection, PSU Failure, Lost connection, Temperature, AES Input, AES Reference, SNMP and moreSpecifications:Dimensions: 19 x 1 3/4 x 11 13/16 [482mm (W) x 44.45mm (H) x 300mm (D)] excluding rear connectorsWeight: 4 Kg /8 lb 13.100 ozPower: Dual AC 90-240V IEC power inlets; 2A 50-60 HzOperating temp: 0C to 45C (32F to 113F)Humidity: 20% RH 70% (0 to 35C/32F to 95F), non-condensingALGORITHMS:IP Algorithms: Tieline Music, Tieline MusicPLUS, Opus, G.711, G.722, MPEG Layer 2, MPEG Layer-3 LC-AAC, HE-AAC, HE-AACv.2, AAC-LD, AAC-ELD, 16/24 bit aptX Enhanced algorithm*IP (uncompressed): Linear PCM16/24 bit 32kHz, 44.1kHz, 48kHz, 96kHz sampling
