ZeroNoise Pit-Link Microphone Helmet Kit - 4 Pin Nexus, 3.5mm Stereo Earplug

This helmet kit is specifically designed for the ZeroNoise Pit-Link GSM system, utilizing a 4-pin Nexus plug. While some other systems might use Nexus plugs, the 4-pin configuration is tailored for the Pit-Link.

The kit provides the necessary connection for 3.5mm stereo earplug speakers, but the speakers themselves are not included. You will need to provide your own compatible earplug speakers if you wish to use them.

Use the included foam spacing discs to position the microphone correctly. It should be close to your mouth to pick up your voice clearly but not so close that it is directly in the airflow of your breath.

The kit is designed to fit comfortably and securely within full-face helmets.

The helmet kit connects to the amplifier unit via a 4-pin male Nexus plug.

Yes, the kit can be used without separate earplug speakers. The audio from the communication system would typically be managed by the connected amplifier.

Check that the 4-pin Nexus plug is securely connected to the Pit-Link amplifier. Verify the 3.5mm earplug connector (if used) is fully inserted. Ensure the microphone is correctly positioned and not obstructed.

Readjust the microphone position using the foam spacing discs. Ensure the microphone is as close to the mouth as possible without being touched by breath. Check that the helmet fit is snug and not allowing excessive external air to enter around the microphone area.

Inspect the 4-pin Nexus plug for any bent pins or debris. Try a different compatible Pit-Link amplifier if available to rule out amplifier issues.
