Hollyland Solidcom C1 Pro Wireless Intercom System with 2 ENC headsets

Hollyland Solidcom C1 Pro – Full-Duplex Wireless Intercom with Dual-Mic ENC

The Hollyland Solidcom C1 Pro is a full-duplex wireless intercom headset system that uses dual-microphone Environmental Noise Cancellation (ENC) technology. It delivers clear team communication in loud production environments. The system stays lightweight and easy to use, and it arrives ready out of the box.

Why choose the Solidcom C1 Pro

The C1 Pro uses DECT 6.0 technology and a wideband audio range to keep speech intelligible. Moreover, it offers reliable line-of-sight (LOS) communication up to 1,100ft (350m). Teams working on sets, live events, or noisy locations will find the ENC and full-duplex operation particularly useful for uninterrupted two-way conversations.

Key Features

• Dual-Mic ENC — Built-in environmental noise cancellation using two microphones for clearer voice pickup.
• PTT Function — Push-to-talk support for controlled transmissions.
• 150Hz–7kHz Wideband Audio — Wide frequency response for natural voice reproduction.
• 1,100ft (350m) Reliable Range — Line-of-sight communication range for typical production layouts.
• DECT 6.0 - Enhanced Stability — Wireless stability suitable for dense RF environments.
• Ultra-long Duration — Designed to run for extended periods during shoots.
• Increased Portability & Durability — Lightweight headsets built for on-location use.
• Ready Out of Box — System ships set up for immediate use.
• Backward Compatibility — Designed to maintain compatibility with previous systems.
• A & B Dual Grouping (Requires HUB) — Grouping options when using a HUB for organized team channels.
• Three-System Cascaded Connection — Ability to connect systems in cascade for larger setups.
• ANNOUNCE Function — Central announcement option for quick, one-to-many communication.

Performance and use

The C1 Pro combines DECT 6.0 modulation and GFSK modulation mode to offer stable wireless links. Its wide frequency response keeps voices natural and intelligible, whether ENC is on or off. Additionally, the system provides a high signal-to-noise ratio and low distortion to maintain clarity on set.

FAQ

Question: What wireless technology and frequency band does the Solidcom C1 Pro use?

Answer: The system uses DECT 6.0 technology on the 1.9 GHz DECT band. Note that the exact frequency allocation can vary by country and region.

Question: How far will the C1 Pro communicate on set?

Answer: The specified line-of-sight (LOS) range is 1,100ft (350m). This is the reliable range under LOS conditions, giving you an idea of typical performance in open environments.

Question: How long do the headsets run, and how long to charge?

Answer: Remote headsets operate for more than 10 hours with ENC on. A master headset runs for more than 5 hours with 5 remote headsets connected and more than 4 hours with 7 remote headsets connected. Charging time is about 2.5 hours.

Question: What noise reduction does the system provide?

Answer: The C1 Pro features dual-mic Environmental Noise Cancellation (ENC) and an ENC value of 20dB±2 to reduce ambient noise and improve voice clarity.

Question: Can I expand teams or group channels?

Answer: Yes. The system supports A & B dual grouping (which requires a HUB) and three-system cascaded connection for larger configurations. It also lists backward compatibility to work with prior systems.

Question: What are the audio quality and technical limits?

Answer: The wideband audio response is 150Hz–7kHz. With ENC off, the fluctuation range is ±6dB; ENC on, it is ±10dB. The system also provides a signal-to-noise ratio of 71±2dB@94dBSPL and distortion below 1% at the specified SPL and frequency range.
