Introduction

EM-27692-C14 is a kind of professional microphones that can be used in applications where the highest quality sound needs to be achieved. It features a patented capsule technology and has a sensitivity of 9mV/ Pa and a linear frequency response of 20 to 20,000 Hz. It offers exceptional sound quality and extremely low self-noise. It is a small-diaphragm condenser microphone ideal for capturing subtle sounds and accurately reproducing them in studio and live sound.The microphone has a wide range of applications, such as recording instruments and vocals in studio and live sound, live broadcasting, conference recording, podcasting, sound reinforcement, and home recording. It\'s also used for measuring sound pressure levels and training in the field.

Working Principle

EM-27692-C14 microphone is a type of condenser microphone that uses an externally powered impedance converter circuit to convert acoustical energy into an electric signal. The word condenser refers to the two metal plates that form the microphone’s diaphragm, or “capsule”. A membrane separates the two plates, and when it moves in response to sound waves, the plates generate an electric voltage across the membrane. This voltage is then amplified and sent to a mixing console or other sound device.The microphone\'s capsule is a two-stage valve consisting of a diaphragm and a backplate. When sounds reach the capsule, the diaphragm is set into motion. This motion causes a change in the air pressure between the diaphragm and the backplate, which causes an electrical voltage to be generated across the capsule. This voltage is then passed to a pre-amplifier, which amplifies it to line level.

Design and Features

EM-27692-C14is a small-diaphragm condenser microphone with a tightly integrated design and a condenser microphone capsule, where the diaphragm is suspended by a precision machined wire-mesh. This ensures maximum sensitivity and sound accuracy. The microphone has a built-in high-pass filter that helps to reduce low frequencies, such as the rumble of traffic or air-conditioning units, and a pad switch to adjust the sensitivity of the microphone for more robust performance.The EM-27692-C14 microphone has a robust metal housing and can be powered via standard 48V external phantom power or an internal 9V battery. It offers an excellent frequency response from 20Hz to 20kHz and an ultra-low noise floor.

Summary

The EM-27692-C14 microphone is a professional and versatile microphone, designed to capture subtle sounds and accurately reproduce them in studio and live sound. It features a patented capsule technology and has a sensitivity of 9mV/ Pa and a linear frequency response of 20 to 20,000 Hz. It has a built-in high-pass filter and pad switch to adjust sensitivity, and can be powered via 48V external phantom power or an internal 9V battery. It is suitable for recording instruments and vocals in studio and live sound, broadcasting, conference recording, podcasting, sound reinforcement, and home recording.
