Full-Duplex Transmission. To prevent interference at events with hundreds of guests, the Hollyland Solidcom M1 Full-Duplex Intercom 4-Beltpack communicates over the 1.9 GHz spectrum. For quicker response time, users can simultaneously talk and listen, just as one would over the phone, thanks to Full-Duplex transmission.

Sidetone Function. The M1’s sidetone function allows you to hear yourself just as someone else would, giving you peace-of-mind that you’re still transmitting, and lets you adjust your audio to ensure clear communication.

Cascade Connection. This kit comes with 4 beltpacks, but if you need more, we carry a version of this kit with 8 beltpacks. If that still isn’t enough, the Solidcom’s Cascade Connection feature can be used to link multiple Base Stations together to support more users at once. Each user can be assigned to different groups, for up to 3 separate channels. Combined with a wireless range of over 1000 feet, and removable batteries to ensure everyone stays connected, the Solidcom M1 is a great solution for larger events with several hundred guests.
