They decided to focus their business on audio products. The company designed a PA system for Notre Dame football coach Knute Rockne. Rockne, who had difficulty being heard at football practices due to health problems that affected his voice, called the new PA system his "electric voice". Rockne's remark inspired the company's name.
In order to take a scientific measurement with a microphone, its precise sensitivity must be known (in volts per pascal). Since this may change over the lifetime of the device, it is necessary to regularly calibrate measurement microphones. This service is offered by some microphone manufacturers and by independent testing laboratories.
A stereo effect is achieved through differences in sound pressure level between two microphones. Due to the lack of differences in time-of-arrival and phase ambiguities, the sonic characteristic of X-Y recordings is generally less spacey and has less depth compared to recordings employing an AB setup.

Lafayette advertised heavily in major U.S. consumer electronics magazines of the 1960s and 1970s, particularly Audio, High Fidelity, Popular Electronics, Popular Mechanics, and Stereo Review. The company offered a free 400-page catalog filled with descriptions of vast quantities of electronic gear, including microphones, speakers, tape ...
Block diagram of the signal-flow for a common feedback loop [1]: 118 . Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
Audio feedback from microphones occurs when a microphone is too near a monitor or main speaker and the sound reinforcement system amplifies itself. Audio feedback through a microphone is almost universally regarded as a negative phenomenon, many electric guitarists use guitar feedback as part of their performance. This type of feedback is ...
Electret microphone capsules This typical electret microphone circuit has a common source configured JFET inside the two-terminal electret capsule. The JFET is externally-powered by the DC voltage V + through a resistor which sets the gain and output impedance. The output audio signal is received though a DC blocking capacitor.
Other microphones introduced by Crown included the PCC-160 directional boundary microphone in 1986, the tiny GLM series and the patented Differoid CM310 in 1987. The SASS stereo microphone was patented in 1989. Garth Brooks was the first performer to wear the Crown CM311A headset microphone in 1993. The CM700 studio condenser was introduced in ...
