Their high output impedance matched the high input impedance (typically about 10 MΩ) of the vacuum tube input stage well. They were difficult to match to early transistor equipment and were quickly supplanted by dynamic microphones for a time, and later small electret condenser devices. The high impedance of the crystal microphone made it very ...
Many types of input transducers can be found in a sound reinforcement system, with microphones being the most commonly used input device. Microphones can be classified according to their method of transduction, polar pattern or their functional application. Most microphones used in sound reinforcement are either dynamic or condenser microphones.
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording .
Microphone diaphragms, unlike speaker diaphragms, tend to be thin and flexible, since they need to absorb as much sound as possible. In a condenser microphone, the diaphragm is placed in front of a plate and is charged. [2] In a dynamic microphone, the diaphragm is glued to a magnetic coil, similar to the one in a dynamic loudspeaker.
Sound waves move the diaphragm, changing the capacitance C, which produces a corresponding voltage change across the capacitor of ΔV = Q / ΔC . [1] The electret's constant charge eliminates the need for the polarizing power supply required for non-electret condenser microphones , though a preamplifier is typically incorporated to boost ...
A Crown Audio brand PZM, the "Sound Grabber II". It is shown with adapters to enable it to be connected to different mixers and audio devices. The mic has an internal battery so that it can be used with consumer audio devices that do not supply phantom power. Boundary mics may have XLR or 1/4" TRS jacks. Some use mini-XLR or 1/8" TRS jacks.
