![]() ![]() True audio compression works by trying to keep ALL audio at a certain level. This is essentially what we call ‘compression’ Since radios have an automatic mic level limiter in them, this means that although you drive the audio harder than needed, the internal circuitry keeps the audio level low enough to prevent over modulation, but when you are quiet, will allow some of the quieter audio to pass through with nearly the same audio levels. Some people over-drive the radio input with their amplified microphones to increase talk power. Still, amplified microphones are popular since are able to keep the mic a comfortable distance away from your mouth and still easily hit 100% or more. As electronics improved and became less expensive, it is difficult to find a radio that will NOT easily hit 100% right out of the box. People added amplified microphones to give the extra talk power they wanted in a lower cost radio. Originally, most price-point CB radios did not have enough microphone amplification to reach 100% modulation levels with normal voice. Power amplified CB microphones have been around almost as long as CB. The following is an independant review of this base microphone, found during a search of the internet: Output A 8 Pin Standard Microphone Plug.Optional foot switch can be plugged into the socket on the rear of the microphone for foot operated PTT. Turn the power switch on ( by selecting ''FM' or ''SSB'' position ), and the level meter indicates the battery condition with power voltage for a few seconds.] Then, the condition returns to receiving mode automatically. Non-Modulation Prevention Circuit built-in.Īfter continuous transmitting for a few minutes, the alarm circuit will be activated with alarm sound for 30 seconds. ![]() The Electret Condenser Microphone ensures clearer voice quality in FM position and better voice quality on SSB.
