The Clear-Com HXII-KB is a 4-gang flush-mountable speaker station designed for HelixNet networked partyline systems hosted by Arcadia or HMS-4X. It provides hands-free and headset operation with backlit keys, dual OLED displays, and assignable keysets that support up to four channels via shift-page access. The unit accommodates dynamic or electret headsets via 4-pin XLR-M and integrates program audio level control for multi-source monitoring.

Dual connectivity options—PoE via RJ45 or powerline terminal block—streamline deployment in permanent installations and broadcast facilities. The swiveling display panel optimizes viewing angles in flush-mount applications, while front-panel configuration enables rapid setup without centralized management tools. Browser-based CCM configuration and central firmware upgrades via host devices reduce lifecycle maintenance overhead.

HXII-KB integrates with up to 24 licensed channels across 64 or 128 HelixNet endpoints, depending on host platform. It supports gooseneck microphones via 3-pin Tuchel connection and offers routing flexibility for four-wire input/output paths. Environmental tolerance spans 32°F to 113°F with 90% relative humidity, suited to control rooms, production suites, and remote truck installations.
