Electrostatic ActuatorEA002 is especially designed for testing the frequency response of 1’’ microphones. It can be placed directly on the diaphragm of a microphone. It also could be used for 1/2’’ and 1/4’’ microphones with the corresponding adaptor.

AS002 is the electrostatic actuator power supply. It have built-in signal amplifier of 30 dB. It can take the signal directly from a data acquisition card. AS011 can provide an 800V, 200V and 0V DC bias voltage to drive the electrostatic actuator.

CS012 Calibration Stand CS012 is a platform for easy testing the technical specifications of the microphone in various situations.
