The Hollyland Solidcom M1 Pro Full-Duplex Wireless Intercom System with 4 Beltpacks and Single-Ear Headsets operates on the 1.9 GHz band, offering clear communication for small- to mid-sized events. Supporting up to 8 users with expandable beltpacks, it features noise cancellation, a wireless range of up to 400 metres, and easy app or web-based setup for professional and reliable 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. Its full-duplex capability allows team members to speak and listen simultaneously, much like a telephone conversation, ensuring natural and uninterrupted communication. Auto-frequency-hopping technology automatically selects the clearest channel, maintaining a stable connection even in busy RF conditions.

Advanced Noise Cancellation for Reliable Audio

Equipped with dual-microphone environmental noise cancellation, the system reduces background noise to deliver clear, broadcast-quality audio. The electret-condenser microphones capture a wide frequency range from 200 Hz to 7 kHz at a 16 kHz sampling rate, making it easier to understand speech in noisy venues such as concerts or exhibitions.

Long-Range and Flexible Coverage

The base stations built-in panel antenna supports a wireless range of up to 400 metres in front and 50 metres behind, suitable for many indoor venues. Adding the included external antennas extends 360-degree coverage with a radius of approximately 300 metres, ideal for larger spaces like stadiums or convention centres. This flexibility ensures your team stays connected across complex event layouts.

Professional Headsets with Sidetone Function

Each beltpack comes with a wired single-ear LEMO headset featuring an intuitive microphone boom that mutes when raised. The sidetone function lets users hear their own voice through the headset, confirming the microphone is active and audio levels are correct. A 3.5mm jack on the beltpack also supports third-party headsets, allowing customisation to suit personal preferences or specific job requirements.

Simple Grouping and User Management

Organising your team is straightforward with the ability to create up to three groups via the base station, app, or web interface. Whether coordinating camera operators, lighting technicians, or stage managers, you can assign beltpacks to groups with a single tap, improving communication efficiency and reducing confusion during events.

Cascade Connection for Larger Teams

If your production requires more than four users, the Solidcom M1 Pro supports cascading two base stations together using a network or XLR cable. This expands the system to support up to 24 headsets simultaneously, accommodating larger teams without compromising audio quality or range. Multiple interface connectors provide compatibility with various intercom setups.

Durable, Ergonomic Beltpacks

The beltpacks feature a double-injection moulded body with a scratch-resistant matte finish for durability and grip. Weighing just 200 grams, they are comfortable to wear for extended periods. The HD LCD screen clearly displays status information, and the three ergonomically shaped buttons prevent accidental presses, even in low-light or high-pressure situations.

Removable Batteries for Continuous Operation

Each beltpack includes two removable lithium-ion batteries that charge fully in 2.5 hours and provide up to six hours of runtime each. This allows for hot-swapping batteries during long events to maintain uninterrupted communication. The base station also supports dual NP-F battery plates and Power over Ethernet (PoE), ensuring reliable power supply throughout your production.

Out-of-the-Box Ready with Easy Configuration

The system arrives factory-paired and ready to use, minimising setup time. Additional beltpacks can be paired and grouped quickly via USB connection to the base station. Configuration is accessible through a dedicated app or private webpage, giving users control over settings without needing specialised technical knowledge.
