Microphones

The MP34DT05TR is a unidirectional miniature microphone used mainly in acoustic measurements. It is designed to be used in telecommunication systems, sound reinforcement systems, musical instruments, and other audio equipment where a small-sized microphone is required. This microphone has been specifically made to operate in productions with high noise levels. It is also capable of capturing sound accurately and repetitively.

Application field

The MP34DT05TR is a microphone suitable for use in recording studios, television studios, live music venues, and for stage and sound production. It is designed to be used in conditions that require consistent and accurate sound recordings.When recording in an environment with high noise levels, the microphone’s Directivity Index (DI) of 10 dB provides sound isolation of ambient noise and enhances the signal to noise ratio. The MP34DT05TR also has a frequency response of 15Hz to 20kHz, making it suitable for recording vocals and drums as well as acoustic and classical instruments.

Working principle

The MP34DT05TR is a condenser microphone, which consists of two parts: a diaphragm and a backplate. The microphone functions when sound waves cause the air between the two parts to vibrate. The diaphragm is made of a lightweight material and vibrates similarly to the backplate, while the microphone’s capsule acts as a circuit to convert these vibrations into an electric signal, which can then be amplified.When subject to a sound wave, the diaphragm moves in relation to the backplate, causing changes in capacitance. This difference in capacitance changes the electric current, and this current is then translated into an electrical signal. The microphone also contains some electronic components to provide better audio quality.
In conclusion, the MP34DT05TR is a versatile microphone that can capture sound accurately in noisy environments. It is suitable for applications such as recording studios, television studios, live music venues, and stage and sound production. The microphone operates on a condenser design principle and uses a diaphragm and backplate to convert sound waves into an electrical signal. With its unidirectional design, frequency response of 15Hz to 20kHz, and Directivity Index (DI) of 10 dB, the MP34DT05TR is an excellent choice for producing high-quality recordings.
