Hollyland Solidcom M1 Pro Full-Duplex ENC Wireless Intercom System with 4 Beltpacks and Double-Ear Headsets

The Hollyland Solidcom M1 Pro Full-Duplex ENC Wireless Intercom System with 4 Beltpacks and Double-Ear Headsets is designed for small- to mid-sized events, supporting up to 8 users with clear, interference-free communication over a 1.9 GHz full-duplex network. Each user gets a wireless beltpack paired with a professional dual-ear LEMO headset, ideal for concerts, exhibitions, and corporate functions.

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 communication means you and your team can speak and listen simultaneously, much like a phone call, allowing for natural, uninterrupted conversations. Auto-frequency hopping technology further enhances signal stability by automatically selecting the clearest channel available. Combined with advanced dual-mic environmental noise cancellation, a high 16 kHz sampling rate, and a wide frequency response from 200 Hz to 7 kHz, this system delivers broadcast-quality audio even in noisy settings.

Stable, Long-Range Wireless Coverage

The base station features a built-in panel antenna that provides reliable communication up to 400 metres in front of the unit and 50 metres behind it in open spaces. Adding the two external antennas extends this coverage to a full 360 degrees with a radius of approximately 300 metres, ideal for larger venues like stadiums, exhibition centres, or concert halls. This flexibility ensures your team stays connected across various event layouts without worrying about dead zones or signal dropouts.

Professional Dual-Ear Headsets with Sidetone Function

Each beltpack comes with a wired dual-ear LEMO headset designed for comfort and clear audio monitoring. The microphone boom features intuitive on/off control by simply raising or lowering it, reducing accidental muting during busy events. A 3.5mm jack on the beltpack also supports third-party headsets, allowing users to customise their setup. The sidetone feature lets you hear your own voice through the headset, confirming that your microphone is active and your speaking volume is appropriate, which is especially useful when working solo or in noisy environments.

Simple Grouping and User Management

Organising your team is straightforward with the ability to create up to three separate groups, such as lighting, camera, or stage management. Group settings can be configured directly on the base station, through the Solidcom app, or via a private webpage. This single-tap grouping streamlines communication by ensuring messages reach the right team members without confusion or cross-talk.

Cascade Connection for Larger Teams

If your production requires more than four users, the Solidcom M1 Pro supports cascading two base stations via a network or XLR cable up to 100 metres long. This expands the system to support up to 24 headsets simultaneously, ideal for larger crews or multi-zone events. Multiple interface options including 2-wire XLR, 4-wire RJ45, PoE power, and cascade ports provide flexible integration with existing intercom infrastructure.

Ready to Use with Durable, Ergonomic Belts

Beltpacks arrive factory-paired and ready to operate immediately, reducing setup time on site. If you need to add or swap units, pairing is easily done by connecting the beltpack to the base station via USB. The beltpacks feature double-injection moulding with a scratch-resistant matte finish for durability and a secure grip. Weighing just 200 grams, they are comfortable to wear for extended periods. The HD LCD screen displays key information clearly, while three ergonomically shaped buttons prevent accidental presses, even in low-light or high-pressure conditions.

Removable Batteries for Extended Operation

Each beltpack uses two removable lithium-ion batteries that charge independently in approximately 2.5 hours. Each battery delivers up to six hours of continuous use, allowing for all-day operation without interruption. The base station supports dual NP-F battery plates and PoE power input, ensuring the system remains powered throughout your event without downtime.
