If you need a communication solution for a small production team, then the Solidcom M1 Full-Duplex Wireless Intercom Solution from Hollyland is an ideal solution. This wireless intercom setup supports up to 8 team members, providing each of them with a wireless beltpack and professional wired single-ear LEMO headset. Ideal for small- to medium-sized events (approximately 100 to 1000 guests), such as a concert, church function, or exhibition, the Solidcom M1 system works to deliver clear and conversational communication without interference and offers easy app or webpage-based setup.

1.9 GHz Full-Duplex Transmission

To avoid interference with other devices, the M1 intercom system communicates over the 1.9 GHz spectrum and offers full-duplex conversations. With full duplex, you can talk to other team members as you would over the phone, with each party being able to talk and listen simultaneously.

Long-Range Communication

The built-in panel antenna on the M1 base station can provide one-way transmission to beltpacks up 1312' away fronting the panel, and an extra 164' at the back (line-of-sight). Auxiliary external FRP antennas can deliver 360° reception at up to a 984' range.

Sidetone Function

When you're alone at an event and need to ensure that your headset and beltpack are transmitting correctly, you can use the sidetone function to hear yourself through the headset. This helps to ensure that your mic is picking up your voice, that your voice volume is properly set, and more.

Cascade Connection

If you need to expand your coverage and team support, you can utilize the cascade connection feature to join this system to a second Solidcom M1 intercom system, linking both base stations together.
