The ZeroNoise Fearless Offroad ClearVoice (part 6100047) is the Fearless ClearVoice without Bluetooth, for crews who want nothing wireless in the car.
It keeps ClearVoice noise processing, the IP65 case with the larger display, the silicone keypad, separate volume controls, the RCA camera output and the ZeroNoise app with over-the-air updates. ZeroNoise’s own guide also shows the radio in and out switched off on this version, so if you run a team radio through the intercom, the standard Fearless ClearVoice is the one to choose.
We supply it with two male leads, two female leads or one of each. Male leads plug straight into a female Nexus socket: every Bell rally intercom helmet, the Sparco Flux RJ-i, Flux RJ-i Carbon and Prime RJ-i Supercarbon, and the OMP J-Rally. Female leads take a male Nexus plug: the ZeroNoise helmet kits, and Stilo WRC-type helmets through the Stilo AC0204.2 lead.
Which helmets does this amplifier work with?
Any helmet or headset with a 4-pin Nexus connection, as long as the lead gender matches. Order male leads for a female Nexus socket: every Bell rally intercom helmet, the Sparco Flux RJ-i, Flux RJ-i Carbon and Prime RJ-i Supercarbon, and the OMP J-Rally. Order female leads for a male Nexus plug: the ZeroNoise helmet kits, and Stilo WRC-type helmets through the Stilo AC0204.2 lead. For a driver and co-driver on different genders, choose the one male, one female option. It does not take the 6.35 mm Valiant headsets.
What do I need for a complete working setup?
An amplifier like this one, a wired kit in each helmet, and the leads that join them. If you are starting from nothing, send us your helmet models and whether you want music, phone, or radio in the mix, and we will quote the full setup rather than leaving you to guess at parts.
Is it loud enough for a race car?
These systems are designed around exactly that problem: a straight-cut gearbox and open exhaust are why sound-deadened headsets and speech-focused amplification exist. Set microphone placement right against the lips and you will hold a conversation at full noise. If your car is unusually loud, ask us about the higher-output units.
