Most dynamic microphones are low impedance, however, there are older dynamic microphones that are high impedance, or hi-Z. For example, the Sure 585SA is a hi-Z dynamic microphone. ===Types of Condenser Microphones===There are two types of condenser microphones: a permanently biased condenser, usually called an electret condenser, and an externally biased condenser, usually called a true condenser. #electret condenser#true condenserThe majority of condenser microphones are electret condenser microphone so typically when someone says condenser or electret they are talking about the same thing.==Examples==*Cobra 4-pin hand mic - Dynamic microphone. There's no voltage on the mic element.*Icom SM-6 desk microphone - Electret microphone. There is voltage on the mic element. *D104 original Hi-Z microphone - Dynamic microphone. It is a power mic with its own internal amplifier, however, there is no voltage on the mic element. ==Related==* [[Microphone Impedance for Amateur Radio]]* [[Microphone and Line Input]][[Category:Electronics]][[Category:Consumer Electronics]][[Category:Radio]]
