Frequency Spectrum
- The architecture employs a client-server model where the System Core functions as the central audio engine and configuration server of the system. Beltpacks act as clients, offloading all mixing and routing logic to the Core while providing audio input and output to the system.
- The Beltpack serves as the primary user interface, sending routing and volume commands to the System Core for execution. The Core processes these requests centrally and immediately updates the Beltpack’s local display and tallies to reflect the active system state.
- The system uses the 1.9GHz DECT protocol, employing Time Division Multiplexing, for wireless transmission.
- Devices connect via a pairing mechanism where the Beltpack identifies and joins the system by detecting transceiver beacons that match its stored System ID.
- Roaming is entirely beltpack-driven, with the beltpack autonomously monitoring RF conditions to trigger connection changes. It performs a seamless “make-before-break” handoff, crossfading audio between transceivers before releasing the old link to ensure continuity.
- IP Transceivers bridge the wireless transmission to the network by converting wireless audio into Unicast AES67 streams. These devices rely on Precision Time Protocol (PTP) to synchronize radio transmission timing, ensuring glitch-free handover across the coverage area.

System Beltpack Capacity
FSE-BASE: 16
Arcadia: ≤64
Eclipse: ≤64 per E-IPA / 255 per Frame
Please Note:
Beltpacks use floating ports configured using virtual Roles. Eclipse architecture allows for beltpacks floating between E-IPA cards, staggering transceivers between red and blue networks*, and unattended card redundancy failover.
