Since many years President is producing CB radio’s with electret microphones and a standard 6-Pin connector. Big advantage is that all modern President 6-Pin electret microphones can be used on all President CB radio models.
Electret micro elements need a voltage to function and in the President system this voltage comes direct from the radio. One of the 6-pins brings the power from the CB to the microphone.
That is why you do not need a battery in this NOISE CANCELLING microphone, the DIGIMIKE
The DIGIMIKE is on the market since some time now and the users love the quality. One of them told us that he used the DIGIMIKE in the car with the radio on a good volume. With maximum noise reduction the music from the song on the radio was gone, but some of the voice was still there !
This basicly describes what the microphone is doing: the sound from te surroundings, not being human voice, is filtered away. That makes that your voice is heard a lot better by the other stations listening to you.
EASY TO USE
The DIGIMIKE is user friendly. Unpack the micro and plug it in your President 6-Pin CB radio. Very old models may have a 6-Pin dynamic microphone and in that case the DIGIMIKE makes no sense.
On the top of micro you can change channels up or down and most important you can set the NRC level. NRC stands for Noise Reduction Circuit (same as NOISE CANCELLING). There are 5 levels , test with listeners wat they like best and you are ready to go.
