Hollyland Syscom 1000T-4BP Full-Duplex Intercom System - Station with 4 Beltpacks and Pro Dynamic Monaural Headsets

The Hollyland Syscom 1000T-4BP Full-Duplex Intercom System is an enterprise-grade, 1U rackmountable wireless communications system engineered for professional television studios, OB (Outside Broadcast) trucks, large live event switchers, and theater crews.

Operating on the protected, license-free 1.9 GHz DECT frequency band, this specific system bundle includes the master rackmount hub optimized with 4 heavy-duty wireless beltpacks and Pro Dynamic Monaural (Single-Ear) Headsets. Because the central base station inherently supports up to 8 concurrent wireless connections, this 4-beltpack variant leaves 4 channels completely open for seamless team expansion in the future.

Core RF & Studio Engineering Features

• Carrier-Grade Voice Isolation: Utilizing a specialized wideband 300 Hz to 4 kHz frequency response explicitly tuned for the human voice, the Syscom 1000T strips out muddiness. The bundled professional over-ear headsets feature high-sensitivity dynamic microphones paired with circumaural acoustic isolating padding to block external sound pressure from concerts, sports venues, or PA arrays.

• Integrated Wireless Tally Routing: Features a dedicated DB25 Tally connection interface on the rear of the rack unit. When linked directly into production hardware switchers (such as Blackmagic ATEM, Datavideo, or Sony systems), the hub transmits live tally signals wirelessly. The beltpack LCD screens dynamically alter their background backlight color (Red for Live/On-Air, Green for Preview) to effortlessly guide camera operators.

• Master System Overrides (Mic Kill): The director or engineer seated at the base station maintains ultimate control over communications. By pressing the front panel Remote Mic Kill key, the master operator can instantly mute all active field microphones across every beltpack to clear up chaotic line chatter during critical transitions.

• Fail-Safe Power Redundancy: Built with a dual-topology internal power grid. The 1U hub accepts standard AC mains wall power (100–240V) while simultaneously featuring a secondary 4-Pin XLR DC input (10–20V). If a venue circuit breaker trips or a generator goes down, the system shifts to your backup V-mount battery line instantaneously without dropping a single word.

💡 Multi-System Facility Chaining Tip: When your production network scales past the native 8-user limitation of the base station, the Syscom 1000T does not require replacement. By outputting through its analog 3-pin XLR Audio or specialized 4-wire data interfaces, you can cascade multiple Syscom hubs together, or interface directly into legacy analog 2-wire platforms (like Clear-Com or RTS), instantly uniting your wireless team with a permanent studio installation.
