Hollyland Solidcom M1 Full Duplex Wireless Intercom System (4 Belt Packs)

This wireless intercom setup supports up to 4 team members, providing each of them with a wireless waist pack and a single-ear wired professional 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 provide clear, conversational communication without interference and offers simple setup based on apps or web pages.

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

Long range communication
The integrated panel antenna on the M1 Base Station can provide one-way transmission to belt packs up to 1312' away in front of the panel and another 164' to the rear (line of sight). Auxiliary external FRP antennas can provide 360° reception up to a range of 984'.

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

Cascade connection
If you need to expand your team's coverage and support, you can use the daisy chain feature to join this system to a second Solidcom M1 intercom system, linking both base stations together.
