David Clark 40666G-01 Headset Adapter

Product Description

Series 3300 Headsets are designed to provide crisp, clear communications and effective hearing protection in highnoise environments. They are engineered to be compatible with David Clark Series 3100, 3400 and 3800 Intercom Systems and Series 3000 Mobile Radio Adapters.

The 40666G-01 is a simple Headset Adapter that allows users of Series 6000 Two-Way Communication Headsets to use their portable radio headset with the Series 3800 Vehicle Intercom System.

It is designed with a mating jack that accepts the U-174/U type plug from a Series 6000 Headset, and routes the connection through a microphone amplifier before terminating through a 3 foot straight cord to a standard ¼” stereo plug for interface to a high-impedance Series 3800 headset station.

With a miniature enclosure, attachment clip and unobtrusive presence, the 40666G-01 provides an economical solution for fire departments wishing to maximize their investment in communication equipment while minimizing operational downtime from otherwise changing headsets for multiple tasks.

Features and Benefits:

  • Crisp, clear communication in demanding environments
  • Miniature enclosure houses all components
  • Internal microphone amplifier converts the unamplified electret microphone from a Series 6000 headset for compatibility with Series 3800 Vehicle Intercom System
  • Protected TJT-120 Headset jack accepts U-174/U plug
  • Attachment clip allows enclosure to be secured on turnout gear or belt/harness
  • 3 foot straight cord terminates in ¼” stereo plug for interface to high-impedance Series 3800 headset stations
