All Details About CB Microphone Wiring

January 3, 2019 By Joe Talbert 3 Comments

Many people asked me about microphone wiring. That’s why we have created this page to help people and make them understand that all microphones wired are not the same. Different manufacturers may use a different way to wire microphone.

For example, Cobra 4 Pin radios are wired 1) Shield 2) Audio 3) Transmit 4) Receive while Midland 4 Pin radios are wired 1) Audio 2) Shield 3) Receive 4) Transmit.

The list below offers some CB microphone wiring information.

    I’m in an office environment using a vehicle CB with a proper, regulated power-supply as a de-facto base-station with a 24′ (24 foot) roof mounted antenna.

    The CB and microphone are too far from the desk, causing a great deal of inconvenience. I would like to create a splitter for the microphone so that I can use two(2) microphones, the CB and original, hand-held microphone would remain where they are and the new microphone, an A-Static desk-top model would have a longer cord and be placed on the desk.

    Ideally, the PTT button on the desk-top microphone should render the hand-held microphone temporarily disabled so that there would only be one microphone able to transmit at a time. Is this possible?

    The existing system consists of a Cobra Vehicle (I have several) CB with a four(4) pin hand-held microphone. The A-Static desk-top microphone is also a four(4) and does work properly on the CB.

    Would you have any suggestions on how to properly wire such a microphone splitter configuration?

    Any help would be greatly appreciated.

    BTW, I have reasonable degree on knowledge on basic DC electricity.
    I also have all the parts and tools I need, since I started to work on this about 2-3 years ago.
    Ie, multi-meter, soldering iron, female four (4) pin connectors, project box, spare wires and spare CBs and micorphones for testing at home, first.

    Thanks much!

    Andy
