Clear-Com LQ Series IP interface

Clear-Com’s HX Digital Matrix, LQ Series of IP interfaces, and Agent-IC mobile app have been critical in enabling seamless communications for remote-production activities during the coronavirus pandemic. Agent-IC has been used extensively to provide an easy-to-implement communication solution between facility-based staff and production teams on location for field reporting, live event production, remote coordination, and other critical tasks. Literally at-home production personnel who have downloaded the app onto their smartphone, tablet, or wearable device can connect to a host Eclipse HX digital matrix or local and remote LQ IP interfaces over 3G, 4G, LTE, and Wi-Fi networks. App users have a fully functional intercom panel that can monitor the intercom system and receive IFB feeds. LQ can extend the capabilities and intercom channels of an Eclipse HX system to one or more remote locations by positioning an LQ device at the destination location and interfacing with Clear-Com devices, including wired beltpacks, SIP clients, or any Agent-IC mobile app user. Local and remote LQ devices can host up to 48 Agent-IC users, where LQ acts as a server for the app. With a host Eclipse HX matrix, many more Agent-IC users can access the production intercom remotely; the number able to access the main intercom can vary depending on the quantity of IP ports on the E-IPA cards. LQ devices can link industry-standard 2-wire intercom and 4-wire audio systems, irrespective of brand and platform. They also work with SIP telephony systems, allowing Clear-Com’s portfolio of intercom systems to seamlessly connect with VoIP phones.

Unity Intercom full-duplex production intercom system connects users from anywhere in the world over wired, Wi-Fi, or cellular links and allows simplified remote broadcast production. The system comprises two parts: the Unity Intercom server software installed on a Mac computer and the remote talk and listen client applications on iOS, Android, Mac, or Windows operating systems. The Unity Intercom Server handles audio routing, channel setup, and user management for all Unity clients. The client applications connect over wired, Wi-Fi, or cellular connections to talk and listen on independent PL channels or point-to-point private communications with individual users. Each client app can communicate with up to 128 PL channels which can be organized into as many as 64 groups. All clients have the ability to receive up to 64 external audio sources on the Unity apps. A common practice is to bring in Dante audio using Dante Virtual Soundcard (DVS) or any external I/O device connected to the Mac Server (Thunderbolt/USB). This allows users to be connected to traditional comms systems or even monitor up to 64 audio feeds remotely. This has been especially crucial for many “at-home” productions this past year. The Unity Max license removes the normal 63-user maximum and allows as many users to be online concurrently as the Mac computer can handle. Some productions have had more than 500 active online users at the same time on a single Mac server.
