Description
The ZN Digital Amplifier has been completely reengineered delivering superior performance, durability, and user control. 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-mount connectors replace traditional in-line types increasing connection stability.
At the core of the unit is a high-performance digital processor powered by ClearVoiceâ„¢ 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. Housing constructed with anti-shock, anti-vibration silicone for operational stability.
Compatibility: All Bell helmets, ZeroNoise intercoms and headsets, and any helmet using Nexus connectors.
