Hollyland Mars T1000-4BP Full-Duplex Intercom System, Base Station, 4x Beltpack, Pro Dyn. Monaural Headset, Antenna, Carton Case

The Hollyland Mars T1000-4BP (Carton Case Edition) is a full-duplex wireless intercom system engineered for 5-user crews (1 base station director + 4 mobile field operators).

This version features the exact same core hardware, beltpacks, and dynamic headsets as the standard kit, but ships in a cost-effective, eco-friendly cardboard carton box instead of a heavy-duty, hard plastic flight case. It is a favorite for local production studios, houses of worship, and corporate setups where the system stays permanently installed or is integrated into an existing third-party rack-mount road case.

Core Hardware & Engineering Strengths

• 5-User Synchronous Full-Duplex Ring: Operates like an open telephone conference. The Base Station hosts a dedicated headset interface for the director, connecting them natively to 4 wireless remote beltpacks. Everyone can speak and listen simultaneously without pushing buttons, completely avoiding the word-clipping and latency issues of standard walkie-talkies.

• Pro Dynamic Monaural Headsets: Built specifically to isolate vocals in loud environments. Unlike sensitive consumer electret mics, these high-end headsets feature professional dynamic noise-insulating microphones that ignore venue PA systems and stage rumble to prioritize clear human speech.

• Dual High-Gain Omnidirectional Antennas: The base station utilizes two external, high-efficiency fiberglass stick antennas. This spatial diversity configuration ensures stable signal coverage and prevents dead zones in venues built with heavy steel or concrete framing.

• Milled Aluminum Beltpacks with OLED Telemetry: Each beltpack is constructed from CNC-machined aluminum alloy and incorporates a front-facing screen. Operators can track their signal strength (RSSI), battery level bars, and active communication status (Talk/Mute) at a glance.

Power Infrastructure & Field Lifespan

Each remote beltpack utilizes an internal 1,600mAh Lithium-Polymer battery that recharges directly through a 5V USB-C port, while the base hub offers complete power redundancy for flexible location work:

[ BASE HUB POWER ARCHITECTURE ]
├─ Main Power: AC Wall Adapter (7V to 36V DC locking input)
├─ Field Power: Dual rear-mounted Sony NP-F (L-Series) Battery Plates
└─ Hot-Swap Logic: Swap out an NP-F battery mid-broadcast without killing the crew's audio loop

💡 System Expansion Cascading Potential: If your crew layout eventually outgrows the out-of-the-box 4-beltpack limit, you can scale this ecosystem upward. The base station features an RJ45 network cascade port on its rear layout. By running a standard Ethernet cable into a secondary Mars T1000 Base Station, you can cleanly link the two systems together—instantly doubling your mobile network footprint to support 8 simultaneous wireless beltpacks across the venue.
