Popular microphone connector from 1930s to 1980s, originally manufactured by Amphenol. Amphenol sold this production to WPI Interconnect in early 1980s. The Amphenol 80-MC2M, which mates with the 80-PC2F, microphone connector was popular with American radio manufacturers (1950s to 1970s). The Amphenol 80-PC2F connector, that mates with the 80-MC2M
The Modulator has a similar setup to the Whelen WPS 2700, 2800, 2900, and OmniAlert omnidirectional speaker arrays. The Whelen arrays have single driver cells, [3] while Modulators have multi-driver cells. The American Signal I-Force siren, which uses stacked, elliptical speaker cells that provide omnidirectional sound output, is also similar ...

Founded in a Deep River, Connecticut garage in 1952, [ 1 ] Whelen has become a provider of warning lights, white illumination lighting, sirens, and ...
Provided that the microphones are reciprocal in behaviour, which means the open circuit sensitivity in V/Pa as a receiver is the same as the sensitivity in m 3 /s/A as a transmitter, it can be shown that the product of the transmission factors , , and the acoustical transfer impedance equals the electrical transfer impedance.
A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music.
It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. [1] The diaphragm of the microphone responds to changes in air pressure caused by sound waves. That is why the instrument is sometimes referred to as a ...

When concealing the mic is important, such as with film production, a smaller housing may be desirable. Sanken's CUB-01 boundary microphone has a 32 mm diameter and 12 mm height, which makes it easier to hide in TV and film field shooting and easier to reposition or temporarily mount in locations (e.g. taping it onto the inside ceiling of a car).
