The ZN Wired Wireless Amplifier has been fully reengineered to deliver enhanced durability, smarter functionality, and even more reliable performance.

Now certified to IP65, it offers superior protection against dust and moisture—ideal for demanding rally and offroad conditions. A silicone keyboard improves tactile response and longevity, while panel-mounted connectors replace traditional in-line types for increased mechanical strength.

The updated display is 36% larger, ensuring clearer visibility of key information. Full Zero Noise app compatibility enables easy parameter tuning directly from a smartphone or tablet, replicating the on-device experience.

At its core is ClearVoice™, a real-time adaptive noise-cancellation system that filters out unwanted ambient sounds through intelligent algorithms. By continuously adjusting to surrounding noise levels, ClearVoice™ minimizes engine and vibration interference, isolating the user’s voice for optimal clarity and communication quality.

The ZN Amplifier integrates both wired and wireless military-grade communication for secure, instant, and interference-free operation. Unlike Bluetooth, the system ensures stable encrypted connectivity and automatically switches between wired and wireless modes for uninterrupted performance.

It works wirelessly with Bell Mag-10 Rally Carbon WW and HP10 Rally helmets and is also compatible with any helmet fitted with a standard Nexus connector in wired mode, the WW helmets automatically recharge their internal batteries via the amplifier’s power supply, ensuring uninterrupted performance. However, it is important to ensure that the helmets are fully charged before use.

Additional features include an anti-shock, anti-vibration silicone housing, audio input/output for radios and onboard cameras, a Can-bus interface, and a 12V filtered power cable for clean installation.
