Hollyland HL-Solidcom C1 Pro-4S DH Solidcom C1 Pro 4-Person Headset Intercom

Professional Wireless Intercom System for Clear Team Communication
The Hollyland Solidcom C1 Pro-4S-DH is a full-duplex wireless DECT intercom system designed for hands-free communication in high-noise environments. Featuring dual-microphone Environmental Noise Cancellation (ENC), this system ensures clear and uninterrupted two-way voice transmission, making it an ideal choice for live events, film productions, and broadcast operations. With a completely wireless design and no bodypacks required, it provides exceptional mobility and ease of use for teams that need real-time coordination.

Reliable 1.9 GHz DECT Technology with Long-Range Communication
Operating on a secure 1.9 GHz DECT 6.0 frequency, the Solidcom C1 Pro-4S-DH offers reliable communication with minimal interference. It maintains a stable connection at distances of up to 1,100 feet in line-of-sight conditions, allowing teams to stay connected across large production areas. Whether in a studio, on location, or at a live event, this system provides consistent, high-quality audio transmission.

Dual-Microphone Noise Cancellation for Clear Audio in Loud Environments
The dual-mic ENC system significantly reduces background noise by combining a main directional microphone at the user’s mouth with a secondary omnidirectional mic on the earcup. This advanced noise cancellation feature filters out environmental sounds while enhancing speech clarity. With a wide 150 Hz to 7 kHz frequency response, every command and conversation is captured with precision, ensuring efficient and effective communication.

True Wireless Design with Comfortable Dual-Ear Headsets
The Solidcom C1 Pro-4S-DH features a completely wireless setup, eliminating the need for belt packs or external hubs. Each dual-ear headset is lightweight, dustproof, and water-resistant, designed for all-day comfort. The 360° rotating microphone boom allows users to switch between left- or right-ear orientation easily, and the headset can be muted either by flipping the boom up or by pressing the dedicated mute button on the earcup.

Fast Pairing and Simple Operation for Immediate Use
Setting up the system is quick and hassle-free. A long press on the "A" button on the master and remote headsets automatically pairs the devices in approximately 10 seconds. LED indicators show the headset’s status—blue for ENC enabled, green for ENC off, and red for microphone mute. This intuitive interface ensures users can operate the system effortlessly, reducing downtime and improving workflow efficiency.

Long-Lasting Battery Life with Efficient Charging
Each headset is powered by a rechargeable lithium-ion battery, delivering up to five hours of runtime for the master headset and up to 10 hours for remote headsets with ENC enabled. The system includes an eight-bay charging station for convenient battery management, with a full recharge taking approximately 2.5 hours. With eight batteries included, users can swap out power sources as needed to ensure uninterrupted operation.

Expandable and Backward-Compatible for Larger Teams
The Solidcom C1 Pro system allows expansion by linking up to seven remote headsets to the master unit without requiring a hub. For even larger teams, the separately available C1 Pro HUB Base can connect up to eight remote headsets simultaneously. Additionally, the system is backward-compatible with the original Solidcom C1, allowing teams to integrate newer models with their existing setups.
