Harris Race Radios™ supplies the full Zero Noise (ZeroNoise) range of professional motorsport intercom systems and Bell helmet integration kits across New Zealand and Australia. Developed in partnership with OMP and Bell, ZeroNoise offers communication equipment for rally, circuit racing and endurance competition.
Clear driver–co-driver instructions help crews navigate, coordinate and respond in a noisy cockpit. We generally recommend ZeroNoise over Stilo for rally, particularly when the crew is not using Stilo helmets. ZeroNoise is also a useful choice for jetsprints and off-road applications, with the exact model and installation matched to the vehicle and crew.
Choose your ZeroNoise intercom
Compare the ZeroNoise Fearless Digital Intercom Amplifier and ZeroNoise Fearless ClearVoice Intercom Amplifier. Use each product page for its specifications, price, controls, supplied contents and connection requirements.
Match the helmet, microphone and wiring
ZeroNoise offers Bell helmet integration options. Match the exact helmet kit or headset, microphone, connector wiring and amplifier as one audio system. A matching plug shape does not establish universal compatibility with every Bell helmet, intercom or radio interface. Tell us your equipment models so we can identify the appropriate combination.
An intercom links the occupants inside the vehicle. External team communication needs a compatible two-way radio and the correct interface, programming and aerial installation. For jetsprints and other exposed applications, include mounting and protection from water in the installation plan.
Setup and technical knowledge
Read our motorsport communications services and technical knowledge guide for application-led system advice, helmet matching, radio integration and noise-control explanations. Continue with How to Set Up a Motorsport Intercom System for connection planning, or the NZ/AU off-road intercom guide for vehicle and crew considerations. For a particular ZeroNoise model, start with its product listing above.
ZeroNoise manuals and downloads
Use our ZeroNoise manuals and downloads library for the Fearless WW and Pit-Link user guides, catalogue information and technical background. Select the instructions for your exact model and revision: the Fearless WW guide is specifically for the Wired-Wireless system, not a universal manual for earlier Fearless Digital or other ClearVoice versions. Contact our team if you need help identifying the correct instructions.
