Hollyland Solidcom C1 Pro Roaming Hub 20S Full-Duplex Wireless Intercom System with 20 Single-Ear Headsets (G-Mount, 1.9 GHz)

Designed for mobile production teams and featuring dual-mic Environmental Noise Cancellation (ENC) for use in loud environments, the Hollyland Solidcom C1 Pro Roaming Hub 20S is a full-duplex wireless DECT intercom system with hub engineered to provide clear audio and all-day wearing comfort in a true-wireless design with no bodypack required. This configuration includes 20 single-ear headsets, along with 40 rechargeable batteries, three 8-bay charging stations, and accessories.

The system transmits in the 1.9 GHz spectrum and uses proven DECT 6.0 technology to ensure secure and reliable transmission at a line-of-sight range of up to 1600'�making it well suited for a variety of applications, including film/TV production, concerts, and live events.

• This version of the Solidcom C1 Pro Roaming Hub features a G-mount for use with compatible external batteries, allowing you to take the system anywhere the action leads.
• In addition, the Roaming Hub features industry-standard 5/8� and 3/8� mounting holes, which directly enable the attachment of a variety of accessories, such as tripods, light stands, and more, thus assuring hassle-free installation on sites.
• Up to 6 groups are available, making it highly useful for professional scenarios that call for communication among multiple function groups such as productions, camera crews, lighting, and many more. You can also assign roles and customize the number for each type of role for better coordination.

• The single-ear headset design is dust and water resistant and designed to provide a comfortable all-day wearing experience.
• Using the Roaming Hub conveniently eliminates the need for a specific master headset.
• For clear communication in loud environments, engage the dual-mic ENC (Environmental Noise Cancellation) feature.
• The ENC algorithm combines the main directional microphone at the speaker's mouth with a secondary omnidirectional environmental mic on the earcup to cancel out unwanted background noise for more intelligible speech.
• The microphone's wide 150 Hz to 7 kHz frequency response ensures detailed voice capture to keep your team working efficiently.

• The USB Audio Class (UAC) function featured on the Roaming Hub facilitates joining cloud meetings anytime running on Zoom, Skype, or other meeting programs.
• Simply connect your personal computer to the Roaming Hub via its USB interface. This seamlessly brings your on-site and remote teams together, facilitating team interaction and creativity wherever your teams are located�without the need for sound capture cards.

• A built-in Bluetooth module on the Solidcom C1 Pro Roaming Hub shows the remaining battery life in the headsets and provides users with easy access to modify settings directly from their mobile devices via a specially developed app. Bid farewell to long walks to the Roaming Hub just for parameter adjustments.
• Each headset runs on a single rechargeable battery
• Each remote headset will last for up to 10 hours on a single battery charge with the ENC engaged
• Each battery fully recharges in 2.5 hours
• Three 8-bay battery charging stations and three AC adapters are included.

• The C1 Pro Roaming Hub is backward-compatible with the Solidcom C1 system.
• You can easily daisy-chain different systems as needed on site to meet even more complex operational requirements.
