Microphones

The TO-30023-000 is a general-purpose microphone which operates in nearly all types of applications. The TO-30023-000 is a low-impedance dynamic microphone, providing robust audio quality and excellent signal-to-noise ratio. It is perfect for speech intelligibility, recorded narration, and presentation.

Application Field

The TO-30023-000 microphone is suitable for a wide variety of applications, including conference recording, telephone calls, video conferencing, digital recording, vocal music, radio station voice-over, and studio recordings. It can be used outdoors as well as indoors. It is an excellent choice for voice amplification in small- to medium-sized spaces. It is especially suitable for run-and-gun documentary recording, as its compact size allows it to be easily transported and setup.

Working Principle

The TO-30023-000 utilizes a capacitor-electret transducer. It is commonly referred to as a dynamic microphone, although it does not employ a magnet and coil (as is the case with most dynamic microphones). Instead, the transducer in the microphone uses a thin metal diaphragm which is electrically charged. When sound waves strike the surface of the diaphragm, the frequency and amplitude of the sound cause the diaphragm to vibrate. This motion is then detected by an internal amplifier, and processed into an electrical signal.

The dynamic nature of the TO-30023-000 microphone ensures excellent noise isolation, and produces less distortion than a condenser microphone, as the frequency response is flatter. The robust construction of the microphone also results in better off-axis sound rejection, as well as superior low-frequency handling.

Conclusion

The TO-30023-000 is a general-purpose microphone which is suitable for a wide variety of applications. It utilizes a capacitor-electret transducer, which produces excellent audio quality and noise isolation, as well as superior low-frequency handling. It is designed to be robust and reliable, making it an excellent choice for any recording and vocal application.
