The Hollyland Solidcom C1 Pro Roaming Hub 20S is a complete full-duplex wireless intercom package: one roaming hub plus twenty single-ear headsets with dual-mic ENC, covering up to 500 m (1,600 ft) line of sight. A single hub manages up to 20 users across six intercom groups, and cascading a second hub scales the system to 40 users with seamless roaming and automatic handoff as crew move between coverage areas. It is a fast-deploying comms backbone for OB trucks, multi-stage events, theatres, arenas and rental stock, with USB Audio Class for tying in computers and remote callers.
