Hollyland Solidcom C1 Pro-Hub4S ENC 5-Person Full-Duplex Wireless Intercom System with Hub (1.9 GHz)

Hollyland Solidcom C1 Pro-Hub4S – Dual‑Mic ENC and 1.9 GHz DECT Full‑Duplex 5‑Person Intercom

The Hollyland Solidcom C1 Pro-Hub4S is a full‑duplex wireless intercom system that combines dual‑microphone Environmental Noise Cancellation (ENC) with reliable 1.9 GHz DECT 6.0 transmission. This Hub-based kit provides one wired single‑ear headset and four wireless single‑ear remotes, plus rechargeable batteries, an 8‑bay charger, and essential accessories for media production, concerts, and live events.

Key Features

• Dual‑mic Environmental Noise Cancellation for improved speech intelligibility in loud environments.
• Proven 1.9 GHz DECT 6.0 technology for secure and stable wireless transmission.
• Includes a hub with a wired headset plus four single‑ear remote headsets.
• Wide frequency response for clear voice reproduction.
• Line‑of‑sight operating range up to 1100' (approximately 350 m).
• Flexible mute options: dedicated Mute/PTT button or rotate the boom to mute.
• Rechargeable batteries with an included 8‑bay charging station and AC adapter.
• Expandable system and backward compatibility with Solidcom C1.

Dual‑Mic Environmental Noise Cancellation (ENC)

Use the dual‑mic ENC when you need clear communication in noisy environments. The system combines a primary directional microphone positioned near the speaker’s mouth with a secondary omnidirectional environmental microphone on the earcup. Together, these mics and the ENC algorithm reduce background noise and echo, making speech more intelligible for the team.

Additionally, the microphone captures a wide frequency response from 150 Hz to 7 kHz to preserve voice detail and support efficient on‑set coordination.

True‑Wireless, Self‑Contained Headsets for Two‑Way Communication

The C1 Pro provides a portable, hands‑free coordinating experience for production crews and event teams. The system supports real‑time two‑way communication at line‑of‑sight distances up to 350 meters (about 1100 feet). The Pro headsets improve portability and durability compared to the original C1, and the single‑ear design is dust and water resistant to suit all‑day wearing needs.

Hub with A/B Grouping and Professional Options

The included Solidcom C1 Pro hub introduces a new interface and a more stable wired headset connection for professional setups. The wired hub headset also uses ENC to minimize background noise and echo for the hub operator.

Use the hub’s A/B grouping to separate communications into distinct groups, reducing the chance of interruptions and improving coordination between teams. The hub also supports multiple power supply options, including NP‑F battery, V‑mount battery, G‑mount battery, and DC power to fit different production power workflows.

UAC for Cloud Meetings and ANNOUNCE Function

The hub supports USB Audio Class (UAC) so you can connect it to a computer and join cloud meetings on Zoom, Skype, or other platforms. This makes it easy to link on‑site teams with remote participants and keep everyone in sync.

In urgent situations, the hub offers an ANNOUNCE button that mutes all remote headsets and lets the wired hub operator deliver direct instructions that the entire team hears without distraction.

Rechargeable Batteries and Charging Station

• Each remote headset runs on a single rechargeable battery.
• Remote headsets provide up to 10 hours of operation with ENC engaged.
• Each battery fully recharges in approximately 2.5 hours.
• An 8‑bay battery charging station and AC adapter are included in the kit for convenient multi‑battery charging.

Expandable System and Backward Compatibility

The C1 Pro system is flexible for growing teams. Without a hub, you can link up to 7 remote headsets to a master headset. With the included C1 Pro HUB base, the system supports up to 8 remote headsets at once.

The C1 Pro is backward compatible with the Solidcom C1 system. The hub can interconnect different systems and offers 2‑ and 4‑wire audio input/output interfaces. In addition, up to three hub‑based systems can be cascaded over an IP network to expand coverage and meet complex on‑site coordination requirements.

What’s Included in this Configuration

• 1 wired single‑ear headset that connects to the hub
• 4 wireless single‑ear remote headsets
• Rechargeable batteries for the headsets
• 8‑bay battery charging station and AC adapter
• Hub unit and accessories

FAQ

Question: Can I connect this hub to a computer for virtual meetings?
Answer: Yes. The hub supports USB Audio Class (UAC), so you can connect it to a PC and use Zoom, Skype, or other meeting software to integrate on‑site and remote participants.

Question: How many headsets can I use with this system at once?
Answer: Without a hub you can link up to 7 remote headsets to a master headset. With the included C1 Pro HUB base, you can use up to 8 remote headsets concurrently. Additionally, you can cascade up to three hub‑based systems via an IP network for larger setups.

Question: Will the system work in noisy environments like concerts or busy sets?
Answer: Yes. The dual‑mic ENC combines a directional mouth microphone with an omnidirectional environmental mic on the earcup and processes noise to improve intelligibility. The microphone covers a wide 150 Hz to 7 kHz frequency response to retain voice detail.

Question: What power options are available for the hub on location?
Answer: The hub supports multiple power solutions including NP‑F batteries, V‑mount batteries, G‑mount batteries, and DC power, enabling flexible deployment in different production environments.

Question: Is the C1 Pro compatible with earlier Solidcom C1 equipment?
Answer: Yes. The C1 Pro is backward compatible with the Solidcom C1 system, allowing you to interconnect systems and expand communications using 2‑ and 4‑wire I/O or cascade multiple hubs over IP.
