Unique Features
Drone detection
Silynx Drone Detection is an advanced audio enhancement mode designed to help operators hear distant drone activity earlier and more clearly. When activated, the system amplifies the specific frequency ranges produced by drone motors and rotors-making these sounds stand out from the surrounding environment.
This enhanced acoustic awareness allows users to detect drones sooner than they normally would by ear alone, improving readiness during patrols, perimeter security, reconnaissance, or urban operations.
Simple, intuitive, and effective, Drone Detection gives teams an additional layer of awareness exactly when they need it.
Net Monitoring
Net Monitoring gives operators instant clarity and control when working across multiple communication networks. With the FORTIS dual-comms configuration, the system intelligently separates incoming audio-primary radio to one ear, secondary radio to the other-allowing the user to immediately distinguish which network is active without breaking focus.
This natural left/right audio separation enhances situational awareness, reduces confusion during high-traffic communication, and ensures the operator never misses critical information. PTT buttons are independently assigned to each network, enabling rapid, instinctive transmission on the correct channel.
Whisper Mode
Whisper Mode allows operators to communicate clearly in quiet environments by using the environmental microphone on the Protego Pro earpiece. This mic is highly sensitive to low-volume speech, making it ideal when the user needs to speak softly without raising their voice.
When noise levels increase, the operator can instantly switch back to In-Ear Mode, which uses Silynx’s proprietary “talking from the ear” technology. In this mode, the foam earbud seals the ear canal, blocking external noise while still capturing the user’s voice from inside the ear with exceptional clarity.
Whisper Mode gives operators the flexibility to adapt their communication style to any environment-quiet or chaotic-ensuring their voice is always heard.
Leak Test
The Silynx Leak Test ensures operators get maximum protection and performance from their in-ear headsets every time they power up. Activated automatically at startup or manually on demand, the Leak Test checks the seal of each earbud and confirms whether the foam tips are properly fitted in the ear canal.
If the seal is solid, the system quickly clears the user to operate with full hearing protection and optimal audio clarity. If not, the user is notified to adjust the fit for improved performance. This simple yet powerful feature helps maintain consistent protection, clearer communications, and reliable situational awareness in any environment.
With Leak Test, operators step into every mission knowing their gear is seated correctly and performing at its best-right from the first second.
Smartphone & EUD Connectivity
The FORTIS platform delivers advanced digital connectivity, allowing operators to interface seamlessly with smartphones, ruggedized tactical tablets, and modern End User Devices (EUDs). Whether through USB-C, Lightning, EUD smart-radio cables, or encrypted Bluetooth wireless links, Clarus II integrates effortlessly into today’s digital battlefield.
Once connected, users gain intuitive control directly from their Clarus system-answering or ending phone calls, adjusting Bluetooth audio volume, and interacting with device functions without ever reaching for the screen. The system also supports data and video transfer from tactical radios to the EUD, enabling live feeds, mission applications, and situational tools to operate in real time.
For app-based communications, FORTIS is fully compatible with leading smartphone PTT messaging platforms such as ESChat and similar mission-critical apps, allowing operators to stay connected across cellular, Wi-Fi, or hybrid networks.
Fortis Control Box
