Hollyland has introduced the Solidcom M1 Pro, a full-duplex wireless intercom system designed for medium-scale productions such as concerts and exhibition venues. Available in four- and eight-user configurations, the system operates over the 1.9 GHz spectrum and supports cascade expansion up to 24 users, positioning it between small crew headset systems and larger wired broadcast infrastructures. Unlike all-in-one headset systems, the M1 Pro uses beltpacks paired with professional LEMO headsets, aligning it more closely with traditional broadcast-style intercom workflows. Let’s look at what the system offers!

Hollyland has been steadily expanding its lineup, recently introducing products like the Lyra 4K webcam, which we discussed in our November podcast, the VCore smartphone monitoring system and the Pyro 5 all-in-one wireless monitor. With the Solidcom M1 Pro, Hollyland shifts back to crew communication, targeting structured production teams rather than individual content creators. To see details on how it works, have a look at their tutorial:

1.9 GHz transmission and audio structure

The Solidcom M1 Pro operates over the 1.9 GHz spectrum, a band that’s generally less crowded than 2.4 GHz when you’re working in RF-heavy venues. In practical terms, that means fewer surprises when you’re working in venues already packed with wireless microphones, in-ear systems, and Wi-Fi traffic.

The system supports full-duplex communication for up to eight users. Hollyland also integrates automatic frequency hopping to maintain stable transmission if interference is detected.

On the audio side, the M1 Pro uses dual-microphone environmental noise cancellation and electret-condenser microphones. It features a 16 kHz sampling rate and a 200 Hz to 7 kHz frequency response, optimized for speech-focused communication. In practice, that aligns with typical speech-optimized intercom design rather than full-range audio transmission.

Range and antenna configuration

The M1 Pro base station includes a built-in panel antenna designed for directional coverage. According to Hollyland, the panel antenna supports transmission up to 1,300 feet (approximately 396 meters) in front of the base station and 160 feet (about 49 meters) behind it in unobstructed environments.

For broader coverage, the system also ships with two external antennas that provide 360-degree transmission in a radius of up to 985 feet (approximately 300 meters). This configuration is intended for larger rooms or venues where crew members are moving continuously rather than working within a fixed frontal field.

Expansion and integration options

While the M1 Pro launches in four- and eight-user configurations, the system can be expanded further through cascade connection. Two base stations can be linked using a standard network cable up to 328 feet (100 meters) or via XLR, allowing support for up to 24 headsets simultaneously.

The base station includes multiple interface options, including 2-wire XLR and 4-wire RJ45 connections, along with PoE/LAN power input. This allows the M1 Pro to integrate into existing wired intercom infrastructures rather than operate solely as a standalone system.

Grouping can be managed directly from the base station, the Solidcom app, or a private web interface, allowing beltpacks to be assigned to separate teams such as lighting, camera, or production. Up to three groups can be configured within a single system, which should be enough for most mid-sized event workflows.

Beltpack design and power management

The Solidcom M1 Pro uses beltpacks paired with wired headsets rather than an all-in-one design. Each beltpack weighs approximately 7 oz (about 200 g) and features an HD LCD for status and grouping information, along with three ergonomically differentiated function buttons to help prevent accidental presses in low-light conditions.

The beltpacks support both LEMO and standard 3.5 mm headset connections, allowing compatibility with third-party options. A sidetone function is included for quick microphone checks when working solo.

Power comes from two removable lithium-ion batteries per beltpack, each rated for up to six hours of runtime and charging in approximately 2.5 hours. A charging station is included with the four-pack kit, and the base station supports dual NP-F batteries as well as PoE power input (which means longer events can be covered with battery swaps rather than downtime for charging).

Pricing and availability

The Solidcom M1 Pro is available in both four- and eight-user configurations, with the choice of single-ear or dual-ear headsets.

Pricing is set at $4,799 for the four-user single-ear package and $4,999 for the four-user dual-ear version. The eight-user configuration is priced at $7,699 for single-ear headsets and $7,999 for the dual-ear package.

Each kit includes beltpacks, wired headsets, a charging station, and the base station. Cascade capability allows expansion beyond eight users when additional base stations are added.

For teams working in medium-sized venues, does the M1 Pro strike the right balance between flexibility and structure? Would you opt for a scalable 1.9 GHz wireless system like this, or stick with a traditional wired intercom setup for similar productions? Let us know in the comments!
