Whats the difference between a dynamic and a condenser mic?
The two main categories of microphones are dynamic and condenser mics. A dynamic mic is the most rugged type of mic, and requires no external power, since it generates its signal with electromagnet effects. Similar to the way a guitar pickup works, the diaphragm in a dynamic mic moves a magnet or a coil when sound waves hit the diaphragm, and the movement creates a small current. Dynamic mics can handle louder sources (guitar amps, drums, etc.) than condenser mics, which are more sensitive. Condenser mics allow the movement of the diaphragm to be registered by the plates of a capacitor, creating an electrical signal that must then be amplified with a built-in amplifier. This means that the condenser mic must receive external power, usually through Phantom Power or via its own special power supply. Condenser mics are often chosen for their sensitivity, and resulting ability to capture a high level of detail for critical applications like studio vocal recording.
