Product description
C-Phone HE4R Communications
The C-Phone HE4R communications system is a rack-mounted diver communication system with an integrated helium speech unscrambler. It is designed for saturation diving and deep diving operations where clear voice communication is essential. As a result, supervisors and divers can communicate accurately, even in helium-rich breathing environments.
Independent Helium Speech Processing
The C-Phone HE4R communications system uses a powerful digital signal processor (DSP) to process four independent speech channels. Unlike systems that combine audio before processing, it treats each channel separately. Consequently, every diver benefits from clearer and more natural speech reproduction.
Each communication channel includes its own unscrambler adjustment. Operators can fine-tune every channel individually to achieve the best possible audio quality throughout the dive.
Flexible Communication Modes
The system supports both 2-wire push-to-talk and 4-wire round robin communication modes. Therefore, dive teams can configure the system to match different operational procedures and project requirements.
A simple user interface allows supervisors to adjust settings quickly during live diving operations. In addition, clearly labelled controls help reduce setup time and simplify day-to-day operation.
Built for Saturation Diving
The C-Phone HE4R communications system includes dual tender inputs and flexible recording outputs. These features support structured dive management while allowing operators to record conversations for training, documentation and post-dive analysis.
Commercial diving companies use the system for saturation diving, offshore construction, hyperbaric operations and deep-water intervention projects. Its rack-mounted design integrates easily into permanent dive control systems while delivering dependable performance in demanding environments.
Whether supporting routine saturation dives or complex offshore campaigns, the C-Phone HE4R communications system provides clear audio, accurate helium speech recovery and reliable communication across all four channels.
