Hollyland Solidcom M1 Pro RRU Base Station

The RRU base station is the heart of the Hollyland Solidcom M1 Pro wireless intercom. It serves up to eight beltpacks in full duplex, offers up to 400 m (1,300 ft) of range on the 1.9 GHz band and cascades with further base stations via IP and 4-wire audio. It is powered over PoE or by an NP-F battery, so it suits the studio as well as the field.

Aluminium body for demanding use. The station has a built-in panel antenna and connectors for two external fiberglass antennas. Groups are set in the station menu using the display and front-panel buttons, or on the device web page or in the Hollyvox app.

The base of the M1 Pro system

The station manages communication for up to eight beltpacks, holds groups A, B and C and links the intercom to further stations and to audio systems.

Connectors along the bottom edge

Power, 4-wire RJ45 audio, USB, 2-wire XLR audio and PoE/LAN sit side by side, keeping the cabling tidy.

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.

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.

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.

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.
