#Hollyland Solidcom M1-4BP Full-Duplex Wireless Intercom Solution - Station with 4 Beltpacks and LEMO Headsets (1.9 GHz)

The Hollyland Solidcom M1-4BP Full-Duplex Wireless Intercom Solution is a professional-grade, turn-key communication package engineered for small-to-medium production crews, church broadcast teams, and live event coordinators.

Operating on the license-free 1.9 GHz DECT 6.0 spectrum, this complete kit includes a master Base Station Hub, 4 wireless beltpacks, and 4 professional single-ear LEMO headsets. Because the central hub natively supports up to 8 concurrent wireless connections, this 4-beltpack variant leaves 4 channels wide open, allowing you to scale up your crew's communication framework in the future without buying a new base station.

Core Hardware & Signal Architecture

• Spatial Diversity Dual-Antenna Engineering: Each beltpack is armed with two external custom-tuned antennas. The internal RF chip constantly samples the incoming signal strength on both antennas simultaneously and auto-switches to the strongest line in microseconds. This spatial diversity layout prevents dropped audio packages caused by "body shielding" when a camera operator turns away from the central hub.

• Intelligent Multi-Department Grouping: Out of the box, the base station allows you to partition your 4 crew members into up to 3 distinct operational channels (Group A, B, and C). For example, you can put 2 operators on Group A for Cameras, and 2 on Group B for Stage Management. Crew members can switch groups instantly by hitting the backlit, color-coded buttons on the front face of their beltpack.

• Dual-Topology Hub Transceiver Antennas: The base station features a hybrid antenna system to adapt to any environment. It houses an integrated panel antenna molded right into its front plate, blasting a targeted directional signal up to 1,300 feet (400 meters) out front. For wide 360-degree stadium setups, you can screw on the included high-gain fiberglass omnidirectional antennas to form a 985-foot (300-meter) operational radius.

• Studio-Grade LEMO 8-Pin Headsets: The kit comes standard with Hollyland's premium single-ear headsets utilizing professional lockable Lemo 8-pin connectors. Unlike standard mini-jacks that can easily yank loose mid-show, these metal connectors lock firmly into place and feature an automatic microphone mute when the boom arm is flipped upright.

Pro System Interfacing & Power Management

The master base station's lower panel is engineered to seamlessly bridge your wireless team directly into pre-existing venue infrastructure:

[ BASE HUB SYSTEM INTERFACE ]
├─ 2-Wire Audio Interface (XLR) ──> Integrates directly with analog theater/concert partyline setups
├─ 4-Wire Audio Interface (RJ45) ─> Links with matrix clear-com or RTS studio installations
├─ IP Cascade Ethernet Port ──────> Connects a secondary hub to immediately double user capacity
└─ Local Configuration Web Server ─> Access via local Wi-Fi to adjust individual mic gains and user labels

💡 Expansion Strategy Tip: Because this kit ships with the full-sized 16-slot charging dock and 8 total batteries (double the number of beltpacks in use), your tech table can constantly keep 4 fresh batteries sitting at 100% capacity. If you expand your team later down the line by purchasing standalone expansion beltpacks, your charging base and hub are already fully prepared to handle the extra load up to an 8-user limit.
