PUI Audio high definition ECM microphones

PUI Audio is excited to expand HD Series microphones in the size range from 4mm to 12mm that uses premium-grade MOSFETs and diaphragms for high sensitivity and superior signal-to-noise ratio. Each microphone features GSM buzz-blocking capacitors. Upgrade the ECM microphone that you use today with a PUI Audio HD series microphone. The HD3 microphones incorporate a three-pin design (drain, source and ground) to reduce self-noise. With wider temperature range, lower noise level, better frequency response and phase control, these new microphones can be used in various high-end applications such as earphone, automotive, voice array as well as extreme fidelity and focused recording of acoustic sources on and off-axis from the microphone. The higher acoustic overload points and tighter tolerances allows these microphones to withstand super-high SPL environments.
