LQ interfaces allow 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.  

Various LQ hardware options are available with 2-wire, 4-wire, and 4-wire GPIO interface in 2-, 4- or 8-port portable or rackmount device.  

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 infrastructure3

Analog Interface Hardware Options 

LQ interfaces are available with factory fitted analog interfaces for connectivity to a variety of 3rd party audio and intercom systems with audio interface ports assignable to any Channel or Direct: 

• 2-Wire Partyline allows interfacing to existing analog partyline intercom system infrastructures or to add partyline user stations or interfaces. 2-Wire ports include software configurable partyline power supply, termination and auto-null. 

• 4-Wire provide the ability to connect analog line-level audio inputs and outputs and include the option to pass through Clear-Com signalling to compatible panels, interfaces, and matrices. 

• 4-Wire with GPIO provides additional isolated Input and Relay Outputs for control events that can be assigned to VOX, Call or to trigger other virtual or physical GPO. 4-Wire with GPIO additionally includes a software configurable pad to allow interfacing to mic level inputs on two-way radios. 

All interface ports include adjustable bandwidth and latency to accommodate a wide variety of network infrastructure quality of service.
