The ClearCom LQ-R4WG8 is a 1RU, 8 Channel, 4-Wire, LQ Series IP Interface with GPIO LQ allows networked interfacing for intercom and audio using standalone devices or linked deployments of multiple decentralized devices over LAN, WAN or Internet infrastructures with audio routing, mixing and transport of specialized control signalling via up to 24 Channels and Direct connections using the Opus codec.
LQ links its channels natively with other LQ interfaces, Gen-IC Virtual Intercom and HelixNet HMS-4X* digital partyline and allows for virtual interfacing using I.V. Direct (/IVC Direct) to Eclipse E-IPA (/IVC32) matrix cards & Arcadia Central Stations or SIP telephone systems over all types of networks.
Architecture
LQ interfaces allow linking up to (6) units into a Link Group which allows non-blocking mixing and routing of Channels and Direct connections over a network using Clear-Com's patented I.V. Core decentralized network mixing technology where all incoming audio is converted into Ethernet streams and intelligently routed to associated interface ports for mixing.
Audio transport
Gen-IC Virtual Intercom interfaces use the low latency Opus codec, supporting interface ports with either 12kHz or 20kHz frequency response, adjustments of data rate, bandwidth, and latency to optimize performance for the quality of service provided by the available network infrastructure.
Link Group
In larger deployments one LQ becomes the Link Group designated leader ensuring the system configuration, channels and assignments are shared by all LQ interfaces in the Link Group and that operation continuous in case of an outage of any Link Group member.
LQ interfaces can link with Gen-IC Premium Virtual Intercom service over the internet providing a way to add a high density of Gen-IC supported Agent-IC and Station-IC Virtual Clients to a dedicated hardware intercom system on-premises or to bridge multiple intercom systems over the internet. LQ interfaces provide 2-Wire, 4-Wire, 4-Wire with GPIO, I.V. Direct (/IVC Direct) and SIP client connectivity to Gen-IC Premium Virtual Intercom.
LQ interfaces can link with HelixNet HMS-4X1 main stations using the HLI-ET2 module over LAN and WAN networks. This allows the main station to use the LQ ports as additional audio input and output to the HelixNet HMS-4X system. LQ device also allows HelixNet users add Agent-IC, Station-IC virtual intercom clients as well as I.V. Direct (/IVC Direct) and SIP1 client interface ports to the HelixNet channels.
