  • Dual-Band RF Support On 1.9 GHz DECT And 2.4 GHz FHSS For Venue Flexibility
  • Make-Before-Break Beltpack Roaming Ensures Uninterrupted Audio During Zone Transitions
  • Four 2-Wire Partyline Ports With Clear-Com And RTS-TW Compatibility
  • Transformer-Balanced 4-Wire Ports With Software-Selectable AES-72 Pinout
  • Dual RJ45 And SFP-Switchable E1 Ports Enable Fiber Transceiver Deployments
  • CCM Browser Configuration Alongside Front Panel Controls For Flexible Management
  • Dedicated Stage Announce Output And Program Audio Input For Broadcast Workflows

The Clear-Com FSII-BASE-II-X5 is a 1RU base station designed for demanding live production, broadcast, and theatrical environments where wireless intercom must integrate cleanly with existing wired infrastructure. It supports up to 25 beltpacks and 10 E1 transceivers operating on 1.9 GHz DECT and 2.4 GHz FHSS, giving production teams the RF flexibility to navigate venue-specific interference without redesigning their system. The client-server architecture offloads all mixing and routing logic to the base station, keeping beltpack operation responsive and reducing on-air latency. Seamless make-before-break roaming ensures beltpack users move freely across transceiver coverage zones without dropout, a critical capability for large stages and multi-room broadcast facilities.

Four 2-wire partyline connections offer compatibility with Clear-Com and RTS-TW analog systems, allowing the FSII-BASE-II-X5 to slot into established party line rigs without forcing a full rip-and-replace. Four transformer-balanced 4-wire line-level ports with software-selectable AES-72 pinout handle matrix and panel integration. A dedicated stage announce output and program audio input add broadcast utility without requiring an external breakout. CCM browser-based configuration alongside front panel controls gives system engineers two independent paths for commissioning and real-time monitoring. The dual RJ45 and SFP-switchable E1 ports support fiber-connected transceiver deployments where copper runs fall short, provided SFP transceivers are sourced per the Clear-Com SFP Compatibility Chart.

For integrators and systems engineers specifying a scalable wireless intercom backbone, the FSII-BASE-II-X5 delivers a breadth of I/O and management capability that positions it above single-protocol wireless intercom solutions. The 12-channel, 12-group, 50-role configuration with point-to-point key assignments gives large productions the granular routing control typically reserved for fully wired matrix systems.
