Solidcom M1 PRO

The Solidcom M1 Pro is a full-duplex wireless intercom made up of a base station and beltpacks with headsets. Each beltpack has a supercardioid primary mic and an omnidirectional secondary mic, and an ENC algorithm uses the second mic as a noise reference to remove up to 20 dB of background noise. Users can work in up to three talk groups (A, B, C), and the beltpack stores 8 preset modes with colour indicator lights.

The system works on the 1.9GHz band with automatic frequency hopping. The base station takes either a built-in panel antenna, with a line-of-sight range of up to 400m in front, or external fiberglass antennas for coverage of roughly 300m in all directions. Several base stations can be cascaded over IP or 4-wire links, and the 2-wire and 4-wire interfaces connect to other Hollyland intercoms, wired audio systems and, with a converter, walkie-talkies.

Each beltpack runs on swappable lithium polymer batteries rated for up to 6 hours and has a 3.5mm jack for third-party headsets. The base station is powered by PoE or NP-F batteries. Settings can be changed from the base station, a web page or the Hollyvox app, which also handle upgrades. Kits come with 4 or 8 beltpacks and single-ear or double-ear headsets.
