The ZeroNoise 6400011 is a 50 cm coiled lead with a female 4-pin Nexus socket at one end and a 3.5 mm stereo jack at the other.
The female socket takes a male Nexus plug, such as the one on a ZeroNoise helmet kit or a Peltor-style kit, and the jack goes to a phone or other 3.5 mm device.
For a helmet with a female Nexus socket, such as a Bell rally intercom helmet, the 6400010 male Nexus to 3.5 mm lead is the matching version. The 3.5 mm jack does not fit the 6.35 mm sockets on the Valiant amplifier.
What does this lead join?
A male Nexus plug, as on the ZeroNoise helmet kits and Peltor-style kits, to a 3.5 mm device such as a phone. For a female Nexus socket, such as a Bell helmet, the 6400010 is the version you need. Our ZeroNoise intercom compatibility guide shows every pairing.
My intercom crackles or cuts out. Is a new lead the fix?
Often, yes. Leads live a hard life being trodden on and trapped in doors, and a damaged lead is the most common cause of noise or dropouts. If a replacement does not cure it, talk to us before replacing the amplifier, as it may be a connector or helmet-kit fault instead.
