Hollyland Solidcom M1-4B-DH Full-Duplex Wireless Intercom, 4 Beltpacks, Dual-Ear Headsets

The Solidcom M1 is a full-duplex intercom for larger teams, built around a rack-friendly base station and up to 8 wireless beltpacks. It runs on the 1.9 GHz band and pairs a base-station panel antenna with a set of external antennas for 360-degree coverage, so a 4-person crew can talk and listen at once across a venue. Self-developed noise cancellation and a 200 Hz to 7 kHz response at a 16 kHz sampling rate give it a broadcast-grade voice, and each beltpack drives a dual-ear LEMO headset.

The built-in panel antenna reaches up to 1,300 ft in front of the base and 160 ft behind, while the external antennas hold a roughly 985 ft (300 m) 360-degree radius. Each beltpack takes two removable Li-ion batteries that charge in about 2.5 hours and run roughly 6 hours each, and multiple bases can be cascaded for up to three talk groups. This 4-user kit ships with the base station, 4 beltpacks, 4 dual-ear LEMO headsets, 8 beltpack batteries, a charging base, antennas, a hardshell case, and the PoE, cabling, and mounting accessories.
