Condenser Microphones UC Series
Sound field and sound pressure models
In ordinary measurements, the placement point at the microphone has an impact on sound pressure at the measurement point at high frequencies. Sound field microphones are designed to flatten frequency characteristics by taking that impact into account in advance. They are used for ordinary measurements.
In contrast, sound pressure microphones are designed to have flat frequency response for the sound pressure applied to the diaphragm without taking the impact on the surrounding sound field into account. They are used for measurements in reverberant room or using couplers.
Preamplifiers NH Series
Preamplifier Overview
A preamplifier with high input impedance and low output impedance is required in order to faithfully transfer the voltage converted by the microphone to the subsequent amplifier.
In the preamplifier, the electrical circuit and 7-pin connector have a unified structure and various models are available to ensure the optimal combination for the type of microphone and diameter. A conversion adapter is used when using a microphone with a different diameter.
