LQ IP interfaces are compact boxes that enable connection of 2-wire partyline and 4-wire audio devices over LAN, WAN or Internet IP infrastructures. LQ is available in 2-wire (LQ-2W2) or 4-wire (LQ-4W2) options. The LQ-2W2 is both Clear-Comand RTS compatible. Two standalone partyline intercom circuits can easily be constructedby connecting two LQ-2W2 interfaces. The LQ-4W2 can interconnect with devices, such as analog ports of any matrix intercom system, analog telephone circuits, two-way radio gate-ways and audio consoles. A maximum of six LQ IP devices can be linked together in any 2- or 4-wire combination.

Audio Assignments
At least two ports must be associated to a channel. When the two or more ports are added to a channel, it becomes a Virtual Partyline (VPL).

Both LQ devices have two Neutrik etherCON series lockable RJ45 chassis connectors for network connectivity. The LQ-2W2 has two 3-pin XLR-F audio port connectors for partyline audio. The LQ-4W2 has two additional Neutrik etherCON audio port connectors for analog 4-wire audio.

The LQ-2W2 can power the partyline, allowing the user to connect a beltpack without the need of a power supply to locally power the line. A total of 5 beltpacks can be locally powered or one beltpack can be powered using PoE.

Network Technology
The LQ devices use the low-latency OPUS codec. The OPUS adjustable audio codec meets various data rate, bandwidth and quality requirements.

Core Configuration Manager (CCM)
CCM is a free browser-based software tool with intuitive menus for quick setup and configuration editing that supports the latest versions of all major browsers on MAC, PC and tablet platforms. LQ devices can be added and removed from the system by editing the configurations via the CCM software.
