CA414 Microphone Phase CalibratorIntroduction：
CA414 microphone phase calibrator is a multi-channel phase calibrator developed by BSWA TECH. It has built-in low-distortion loudspeaker which can form a uniform and stable plane wave sound field inside with the use of BSWA TECH’s power amplifier. It’s suitable for microphone phase difference measurement, microphone array selection and so on.
CA414 includes sound source, microphone holder (with 4 microphone mounting holes) and a strong sound-absorbing end. It can compare phase of four 1/2-inch or 1/4-inch microphones at the same time.
CA414 is only a sound source and comparison coupler. Therefore, perform phase measurement need additional signal generator, power amplifier and acoustic measurement system.
Phase test frequency range up to 6300Hz
Supports up to 4 microphone calibration
Suitable for standard 1/2-inch and 1/4-inch measurement microphone
Modular design, microphone holder is removable and expandable
The sound-absorbing end is made of BASF sound-absorbing foam
Built-in 4-inch loudspeaker, 8Ω, 15W
Microphone phase difference measurement
Microphone array selection
Sound intensity residual index measurement
