The ZN Digital Amplifier has been completely reengineered to deliver superior performance, durability, and user control under the toughest motorsport conditions. Now rated IP65, it ensures high resistance to dust and water—making it a robust choice for rally and offroad applications.

The upgraded design features a 36% larger display for improved readability, and a new silicone keyboard that enhances tactile feedback and reliability, even with gloves. Panel-mounted Nexus connectors have replaced traditional in-line types to increase connection stability and overall system resilience.

At the core of the unit is a high-performance digital processor powered by ClearVoice™ technology. This advanced system uses adaptive algorithms to filter background noise and improve voice clarity in real time. Users can fine-tune noise compression and voice equalisation independently. Full Zero Noise App compatibility allows remote adjustment of all audio parameters via smartphone or tablet.

The ZN Digital Amplifier includes Bluetooth connectivity, audio I/O for radio systems, Can-bus interface, and RCA output for in-car camera integration. Dual volume controls enable individual adjustment for driver and co-driver. The housing is constructed with anti-shock, anti-vibration silicone for operational stability.

A 12V filtered power cable and a quick-mount bracket for roll bar or dashboard installation are included.

Compatibility: All Bell helmets, ZeroNoise Intercoms and headsets, and any helmet using Nexus connectors.
