Print version

A microphone is a device that converts sound pressure into an electrical signal and serves as the sensor in a recording chain. A microphone is a sensor of relative (differential) pressure in gases.

All microphones consist of two systems: acoustic-mechanical and mechanoelectric:

1. acoustic-mechanical
2. mechanoelectric.

The properties of an acoustic-mechanical system depend heavily on whether the sound pressure acts upon one side of the diaphragm (pressure microphone) or on both sides, and in the second case on whether the effect is symmetrical (pressure gradient microphone) or whether fluctuations that directly excite one side of the diaphragm are acting upon it while fluctuations that have passed through a mechanical or acoustic impedance or a time delay system (asymmetric pressure gradient microphone) are acting upon the second side.

The mechanoelectric part of a microphone greatly affects its characteristics.

The supplied microphones are of the ICP standard (with integrated electronics). The ICP-standard preamplifiers in the spectrum analyzers allow you to connect microphones directly without using intermediate amplifiers. Diameter of the microphones: 1/2" (0.5 inches) or 1/4" (0.25 inches).
