Hollyland Solidcom M1 Pro Full-Duplex Wireless Intercom System with 8 Beltpacks & Single-Ear Headsets (1.9 GHz)

The Hollyland Solidcom M1 Pro Full-Duplex Wireless Intercom System with 8 Beltpacks and Single-Ear Headsets operates on the 1.9 GHz band, designed for small- to mid-sized events. It supports up to eight users with professional LEMO headsets, offering clear, interference-free communication over distances up to 400 metres. The system features environmental noise cancellation, removable batteries, and easy app or web-based setup for efficient team coordination.

1.9 GHz Full-Duplex Transmission for Clear Communication

The Solidcom M1 Pro operates on the 1.9 GHz frequency band, which helps avoid interference common in crowded wireless environments. Full-duplex transmission means every user can talk and listen simultaneously, similar to a phone call, allowing for natural, uninterrupted conversations. Auto-frequency-hopping technology further ensures the system automatically finds the clearest channel, maintaining reliable communication even in busy RF areas. With dual-mic environmental noise cancellation and professional electret-condenser microphones, the system filters out background noise, delivering clear, broadcast-quality audio across a wide frequency range of 200 Hz to 7 kHz.

Stable, Long-Range Wireless Coverage

The base station features a built-in panel antenna that supports a wireless range of up to 400 metres in front and 50 metres behind, suitable for many indoor venues. For larger or more complex locations, the two supplied external antennas provide 360-degree coverage with a radius of approximately 300 metres. This combination extends the system’s effective range and ensures stable communication across concert halls, exhibition centres, stadiums, or other event spaces. The extended range and reliable signal help reduce communication dropouts and improve on-site coordination.

Professional LEMO Headsets with Sidetone Function

Each beltpack comes with a single-ear wired LEMO headset, designed for comfort and clear audio monitoring. The microphone boom can be raised or lowered to mute or unmute, giving users quick control without fumbling for buttons. The beltpack also includes a 3.5mm jack for connecting third-party headsets, allowing personal preferences or replacements. The sidetone function lets users hear their own voice through the headset, confirming the microphone is active and the audio level is set correctly. This feature is especially useful when working solo or in noisy environments.

Flexible Grouping and Easy Setup

The system supports up to three separate groups, enabling teams such as lighting, camera, and stage management to communicate independently or together. Grouping is managed via the base station, the Solidcom app, or a private webpage, making it simple to assign beltpacks to different teams with a single tap. Factory-paired beltpacks are ready to use straight out of the box, and additional units can be paired quickly by connecting to the base station via USB. This flexibility streamlines setup and adjustments during fast-paced event environments.

Cascade Connection for Larger Teams

If your event requires more than eight users, the cascade feature allows two Solidcom M1 Pro systems to link together using a standard 100-metre network cable or XLR cable. This expands the system capacity to support up to 24 beltpacks simultaneously, ideal for larger productions. The base station includes multiple interface connectors such as 2-wire XLR, 4-wire RJ45, and PoE/LAN, providing versatile integration options with existing intercom infrastructure.

Durable, Lightweight Belts with Long Battery Life

The beltpacks are built with double-injection moulding and a scratch-resistant matte finish, offering a comfortable grip and durability for demanding event conditions. Weighing just 200 grams, they are unobtrusive and easy to carry. Each unit features an HD LCD screen that clearly displays status information and three ergonomically shaped function buttons designed to prevent accidental presses, even in low-light or high-pressure situations. Two removable lithium-ion batteries power each beltpack, delivering up to six hours of continuous use per battery. Batteries charge independently in 2.5 hours, and the included charging station can recharge all eight beltpacks simultaneously, ensuring your team stays powered throughout the day.

Out-of-Box Convenience and System Configuration

The Solidcom M1 Pro is designed for quick deployment with factory-paired beltpacks and straightforward configuration options. Users can set up and manage the system via the Solidcom app or a dedicated website, offering remote control over grouping, volume, and other settings. The base station supports Power over Ethernet (PoE), allowing for a clean and reliable power supply alongside network connectivity. These features simplify installation and reduce downtime, making the system well suited for both fixed installations and mobile event setups.
