Hollyland Solidcom M1 Pro-8 Double-Ear Headsets

The Hollyland Solidcom M1 Pro is a full-duplex wireless intercom for stage shows, concerts, houses of worship, sports events and broadcast productions. The kit includes the RRU base station, 8× beltpack and 8× double-ear headset with dual-mic ENC that cuts ambient noise by up to 20 dB. Line-of-sight range reaches 400 m (1,300 ft) on the 1.9 GHz band.

Clear talk even in loud environments. Every crew member gets a beltpack with a headset, presses TALK to speak and releases it to mute. Groups, modes and updates are configured on the base station, in the Hollyvox app or on the device web page.

Intercom that cuts through noise

The supercardioid main mic captures the voice, the omnidirectional second mic samples the surroundings and the beltpack subtracts the noise. Colleagues hear a clean voice even at a concert or in a stadium.

A 200 g beltpack

The matte, double-injection-moulded body grips well and copes better with drops. The antennas are detachable, the A, B and C buttons light up in the group colour and volume has 10 levels.

A charging base for the whole team

The base charges eight beltpacks and eight spare batteries in 2.5 hours. Each beltpack comes with two replaceable Li-Po batteries, each lasting up to 6 hours.

Up to eight beltpacks per base station

Further base stations join by cascading over IP or the 4-wire interface, so the system can grow virtually without limit.

400 m range

The built-in panel antenna reaches up to 400 m in front of the station and 50 m behind it; the external fiberglass antennas cover about 300 m in all directions.

Automatic frequency hopping

The system monitors interference on the 1.9 GHz band and switches to clear channels by itself, keeping the link stable.

2-wire and 4-wire audio

The base station connects to other Hollyland intercoms, to 2-wire and 4-wire audio systems and, via the Hollyland converter, to walkie-talkies.

PoE or NP-F battery

The base station draws power over PoE through a network cable or from an NP-F battery in its own slot on the back.

Eight beltpack preset modes

Each beltpack can be set to one of eight modes to match the user’s role – from normal talk and listen to announce or listen-only. A colour indicator shows the active mode.

Three groups, even in a cascade

Users can be split into groups A, B and C – camera, lighting and directing, for example. Groups are set on the base station or on the web page, where the configuration file can be saved and imported.

Cascading several base stations

Two stations are most easily linked via IP or the 4-wire interface; for three or more, both methods are combined. Keep the stations at least 1.5 m apart.

Uninterrupted power

A beltpack battery lasts up to 6 hours and the charging base refills it in 2.5 hours. The batteries are replaceable, and the base station runs on PoE or an NP-F battery.
