MIPRO - Knowledge | Wireless Knowledge

In my opinion, the wireless microphone should be divided into two modules when designed: The front module is the transferring element of the acoustic signal and it transfers the sound into electronic signals. The rear module is the wireless transference system and it transmits the electronic signals of the sound to public-address systems via wireless transmission. The technical theories of these two modules are definitely different, but the principle and goal for the design of them are identical. In order to fulfill the goal of professionals pursuing the original sounds, I decided to choose the ideal condenser capsule as the most important transferring element of the acoustic signal.

Condenser microphones possess superior design features like thin diaphragm, fast transient response, wide dynamic range, low touch noise, miniature and lightweight. They are widely used in communication, audio, sound control, hearing aid and other fields according to different purposes and demands. Although their design and manufacturing technology are more precise and complicated than a dynamic's, they present superior features, especially in professional audio applications. All top end wireless microphone manufacturers supplied with the condenser microphone capsule for world-renowned top singers and performers. Without question, MIPRO wireless microphones are becoming one of the requested choices by sound engineers and audio professionals worldwide for their advanced design, excellent dependability and superior performance.

Converts Sound into Electrical Signal Directly

Condenser microphones adopt a charging / discharging principle of capacitors among conductors using an extremely thin metal or gold-coated plastic diaphragm to pick up sound pressure and convert it directly into an electrical signal. The signal is coupled by high-input-impedance FET to obtain the optimal output impedance and sensitivity. For audio professionals, the reproduction of the "natural sound" is their ultimate goal.

Extremely Wide Frequency Response

Since the diaphragm is the main element to detect sound pressure and convert it into electrical signals, its material and mechanical design has a great influence on the characteristics of its sound quality. Condenser microphones' ultra-light and thin diaphragms are more sensitive to sound pressure. This affects their output audio signal directly, making them capable of an extremely wide frequency response which can easily extend to ultra low frequencies of less than 10Hz and reach ultrasonic frequencies in the tens of KHz.

Thin diaphragm, excellent sensitivity

The diaphragm of a condenser capsule does not have to carry a voice coil, so it can be extremely thin and light, giving it not only superb frequency response, but also excellent sensitivity. The weight of the diaphragm determines its response speed to a sound wave; the lighter the diaphragm gets, the faster this "transient response" will be.

High Sensitivity Gives a Fast Transient Response

The condenser microphone's fast transient response results in an ability to pick up the weakest sound and deliver a clear, bright and precise natural sound. Because the diaphragm is very thin and light, the transient response is fast. The sound pickup is just like a sports car that can accelerate and brake very quickly. Transient response for dynamic is slow due to the much heavier diaphragm and voice coil. Thus, the response to the sound is just like a fully loaded truck that responds slowly when accelerating and braking.

Audio Professionals Appreciate the Extremely Low Handling Noise and Durability The lighter

weight of a condenser microphone has additional benefits. It is more resistant to handling noises which are the bane of many professional audio people, especially in wireless microphones where their pre-amplifier tends to make things worse. When using any microphone, accidental drops and impacts are unavoidable and often cause a malfunction. A condenser microphone is constructed with lightweight plastic parts and metal housing and an even lighter-weight condenser capsule, thus sustaining less damage from impacts.

Condenser Microphone Capsule Features Ideal for Miniature Applications

The condenser microphone's ultra-thin diaphragm with its desirable characteristics of small size, light weight, high sensitivity and superb frequency response is widely used in miniature or ultra-miniature lavalieres.
