The LQ-R2W4-4WG4 enables the connection of both partyline and 4-wire with GPIO audio over LAN, WAN or Internet IP infrastructures in a 1RU panel. LQ Series devices can also connect to Eclipse HX frames via the IVC-32-HX interface card over LAN, WAN and Internet. The partyline connections are compatible with Clear-Com and RTS.Main Features: Two, four or eight ports of audio Rugged and lightweight 2-port units Compact box devices or professional 19″ rackmount devices Up to six devices can be linked together Networked Control Events multi-unicast one-to-many routing Power either by 12V DC power supply or PoE (2 port units only) Remote connectivity to Eclipse HX frame via IVC-32-HX card using G.722 codec 2-wire powering, termination and auto-nulling Low native latency OPUS codec All LQ 2-wire ports are both Clear-Com and RTS TW compatible Browser-based configurator on PC, Mac and Tablet Powered by I.V.Core technologySpecifications:Audio: Resolution: 12, 24 bit Sample Rate: 24, 48 KHz Frequency Response: 100 – 12 KHz or 100 – 20 KHz CODEC: OPUS Partyline Audio: Input Gain: -3dB to +3dB Output Gain: -3dB to +3dB 4-Wire with GPIO Audio: Line Level: (0 dB) Input Gain: -12dB to +12dB Output Gain: -12dB to +12dB Mic Level: (-50 dB) Input Gain: -12dB to +12dB Output Gain: -12dB to +12dB Network Setting: Bit Rates: 16, 32, 48, 64, 128Kbps Packet Size: 5, 10, 20, 40, 60ms Jitter Buffers: 0 – 1000ms Connectors: Network/LAN: EtherCON/RJ45 (female) Partyline Audio I/O: 3 Pin XLR (female) 4-wire with GPIO Audio I/O: 9-way D-type (male) Partyline Output Current: Type: Clear-Com & RTS TW Local DC Powered: 250mA per pair of partyline ports (500mA total) Power Supply: In-line supply with sleeve locking connector Input: 100-240V, 50-60Hz, 1.4A MAX Output: DC 12V, 5A, 60W MAX Environmental: Operating Temperature: +32F – +104F (0C – +40C) Storage Temperature: -67F – +158F (-55C – +70C) Humidity: 90%, non-condensing Dimensions: 19 x 1.79 x 8.8 in (WxHxD) (483 x 46 x 224 mm) Weight: 4.29lbs (1.95kg)
